13. Warning!During test drives, secure the tester with a strap on the vehicle's back seat and connect it to the vehicle using the diagnostic cable. A second person must operate the tester from the back seat. Operation from the front seat is too dangerous, e.g. in the event of airbag activation.

Only for VAS 5051:To supply the VAS 5051 with power from the vehicle battery, use only the 3 m diagnostic cable.

14. Warning!Electrical ignition systems carry voltages of up to approx. 30 kV. Observe general safety guidelines for workshops at all times.

15. Warning!If you open the tester or its accessories without authorisation or carry out improper alterations to them, considerable risk to you and to the device may result.

16. Caution! VAS 5051 - changing fuseFor inline current measurements with the VAS 5051, only a replacement fuse of the same type and same amperage may be installed in order to avoid risks of fire and to protect the device. To order original parts, refer to the corresponding chapters of the operating manual.

17. Caution! VAS 5051B workshop trolley - ventilationWhen operating with the VAS 5051B workshop trolley, make sure that there is sufficient ventilation for the table power adapter of the tester and for the printer. Please note that even when the tester is switched off, the battery charging circuit remains in operation and the printer is online (although in energy saving mode).• Completely open the top cover above the printer or the roll-up door during operation

(depending on the existing workshop trolley).• Heat-dissipation of the table power adapter must not be impaired by objects on top

of it (cable, cloth, etc.).• Pull the mains cable of the workshop trolley to switch off the complete device.

1 General Information

1.1 General Notes

The operating manual software contains the information you will need to operate the tester series VAS 505x, as far as use of the ➚operating modes1 via the touch screen is concerned.

All information about the tester/hardware can be be found in /3/.

This documentation is intended to be used by technically qualified persons with the rele-vant knowledge in the field of vehicle diagnosis and test instruments.

For reasons of clarity the operating manual does not include all details of all versions of the operating modes described. In the same way the contents of the ➚masks shown here may differ to a minor extent from the masks shown by the different tester types.

Tester-specific differences are indicated by text and / or symbols. The model designation "VAS 505x" stands for VAS 5051, VAS 5051B, VAS 5052 and VAS 5053.

The symbols of the corresponding testers appear at the top of pages containing informa-tion valid for several models.

1. The glossary arrow ➚ indicates that the term so marked is explained in chapter 11.

VAS 5051B

VAS 5051VAS 5052

1.3.2 Testers with and without Test Instruments

Within the tester series there are models with and without Test Instruments. For the cor-rect use of the function tests with test instruments available in the Guided Fault Finding, so-called "replacement values" (see section 6.11) must be input via a ➚virtual keyboard in the case of testers without Test Instruments. The measurements are carried out using an external test instrument and the measured values then input via the touch screen.

1.3.3 VAS 5053: administration via partner application

Instead of a hard disc, the VAS 5053 is equipped with a flash (memory) card. It does not have a DVD drive either. This means that some Administration functions cannot be carried out on the VAS 5053 directly. They are therefore 'boarded out' and executed from a part-ner application (see /4/). The communication between the partner (VAS 5051B, VAS 5052 or workshop PC) and the VAS 5053 is carried out via a USB connection.

1.4 Other applicable documents

Associated documents are listed after the table of contents. Please note that each tester has its own hardware description. The software description, on the other hand, since it nearly applies to the entire VAS 505x tester series, is provided in a common operating manual.

The operating manuals are located on the ➚base CD and are loaded onto the tester via the CD. You can also view and print the operating manual if you insert the base CD into the CD/DVD drive of a PC. For more detailed information, see section 9.18.

Caution!Only insert the base CD in a PC that has already been switched on, and remove it from the CD/DVD drive again without delay after you have viewed the operating manual. Since the base CD can be booted, the operating system on your PC's hard drive can be destroyed if the base CD is still in the drive the next time the PC is switched on.

5.1 Overview

The Test Instruments operating mode allows you to set the testing unit with the help of parameter masks and then use the unit to perform tests. Measurement results are dis-played numerically and/or graphically on the screen.

The following functions are available in Test Instruments operating mode:

• Multimeter• ➚DSOIn addition, you can also use the buttons on the navigation bar to switch to the

• Vehicle Self-Diagnosis,• Guided Fault Finding and• Guided Functionsoperating modes. You can only do this if you began your diagnostic session in one of these operating modes.

In the Test Instruments operating mode functions you can also have selected measured values from Vehicle Self-Diagnosis displayed in parallel.

5.1.1 Printing measured values

Via the Print button and then selecting "Screen" you can output a copy of the screen to the output medium specified.

NoteThere are no special Test Instruments provided for the VAS 5052 and the VAS 5053. The measurements required for Guided Fault Finding must be obtained using external testing devices. The results of these measurements can be entered as replacement val-ues via a ➚virtual keyboard.

Caution!Use the Test Instruments only on vehicles and vehicle components.

5.2 Starting the Test Instruments

The Test Instruments are accessed from the start mask by pressing the Test Instruments button.

Fig. 5-1 Start mask, activation of Test Instruments

The "Multimeter" mask always appears after it is started.

Free use

Test Instruments can be programmed to carry out a fault search as part of a function test (see section 6.11) - for example, for checking wiring - or be used as desired. In the latter case you can select instruments directly from the start mask via the Test Instruments but-ton or via non-fixed functions on the navigation bar of the other operating modes. If the Test Instruments are currently in use in a function test they will not be available for free use.

You can change between the "Multimeter" and "DSO" masks via the "Go to" menu.

When Test Instruments is started from the start mask, the "Multimeter" mask always opens first but when switched from the ➚application operating modes it will be the mask last used which will open (multim-eter or DSO).

Function blocks

The buttons on screen for selecting the measurement functions of the two function blocks have differently coloured inscriptions.

The selectable measurement functions are divided into two function blocks (see fig. 5-2):

• Function block 1 (measurements via URD measuring lead, yellow inscription)− Voltage URD− Current URD (VAS 5051B) or inline current (VAS 5051)− Resistance URD− Diode test URD− Continuity test URD

• Function block 2 (measurement via current pick-ups, DSO1 measuring lead, pressure / temperature sensor, green inscription )− Voltage DSO1− Pressure T/D− Temperature T/D− Current via current pick-up

Two simultaneous measurements

You can perform one measurement from function block 1 or function block 2 or you can perform one from each of the function blocks simultaneously (for example see fig. 5-9).

Operate both measurement functions the same way as if each of them was the only measurement currently performed.

If there is a second measurement function selected in the function block which is not needed, you can switch it off by selecting it.

If there is a second measurement function selected in the function block which is not needed, you can switch it off by selecting it again.

The bar indicating the measured value and the Min/Max display under the value display are omitted when two measurements are active at the same time.

Overflow / underflow of measurement values

An overflow or underflow of measurement values for measuring the voltage, current and resistance is indicated by "+++++" or "- - - - -" in the display field and the value display of the Min/Max function.

Calibration

An automatic self-calibration feature is built in to the multimeter functions. It is performed the first time the corresponding button is activated. If you switch ➚measurement types, it will also calibrate in the new measurement type.

This calibration will also take place when you return to the Test Instruments operating mode if has been more than an hour since the last switch.

You can also perform the calibration manually if necessary (see Calibrate button, section 5.3.10).

5.3.3 Direct and Alternating Current Measurement via Current Pick-up


Fig. 5-5 "Multimeter" mask: current measurement with the 50 A current pick-up

If the button is pressed without a current pick-up being plugged in, an error message will appear: "Current pick-up not connected". On the other hand, if one of the four current pick-ups (50 A, 100 A, 500 A or 1800 A) is plugged in, it will be detected automatically and displayed in the right-hand information window. Disconnecting the current pick-up will only be detected during measurement. When measurement is restarted after Freeze Frame, the tester detects if the current pick-up was changed and updates the right-hand information window. After a current pick-up is connected or changed, calibration will be carried out before the first measurement is made.The measurement ranges are adapted automatically to the pick-up type which was detected. Press the display box for the measurement range to switch from automatic to manual measurement range selec-tion. You can reactivate automatic measurement selection by pressing on the display box a second time.

NoteIf carrying out measurements with current pick-ups, remember to recalibrate the pick-up when measuring low currents because of possible magnetisation if you have previously used the pick-up to measure currents in a higher range. For example, this would arise when measuring the quiescent current after switching off the ignition.

When it is pressed, the buttons "Auto set-up", "Auto level", "Auto", "Normal", Single" and "Draw mode" appear below the display field.

Fig. 5-14 "DSO" mask: auto level mode, measuring mode

Measured value acquisition is parametrized with the Measuring mode button.

In auto setup mode the amplitudes of channel A and B, the time base and the trigger threshold are set automatically.

Auto setup is performed only once each time it is called. Measuring mode then switches automatically to auto level mode.In auto level mode the set trigger threshold (percentage threshold in the range ±100 % of the signal amplitude) is tracked automatically so that a triggered image is always visible independent of the signal amplitude.In auto mode measured value acquisition starts automatically in free-running operation when a valid trigger event occurs (according to the pre-set trigger level) or when a wait time dependent on the selected time base has elapsed (no freeze frame).

Test Instruments


VAS 5051B

VAS 5051

In normal mode, cyclical measured value acquisition takes place only when a valid trigger event occurs. If the trigger is missing, a prompt appears in the display box at the right.In single mode, a measurement is taken only once after a valid trigger event.

NoteThe Auto Setup and Auto Level functions can only be used if triggered internally (that is, the trigger signal must be selected as a measure channel) or if the trigger pick-up is used.Auto level and auto setup can only function smoothly with periodic signals with low interference.

In draw mode, measured values are acquired without triggering and the curve is plotted continually from left to right. Draw mode is used for displaying low-frequency signals. Long-term measurement is also possible in draw mode. Extreme values cannot be displayed.

5.4.6 Long-term measurement in draw mode

Long-term measurement allows a time interval to be set for the measurement process in "Draw" measurement mode. After recording, the signal curves are compressed to the width of the window and output accordingly. A zoom function allows you to look more closely at selectable parts of the curves.

When the "Draw mode" button is pressed, the "Long-term measurement" button appears (see fig. 5-18).

Fig. 5-18 "DSO" mask with button for setting long-term measurement

NoteSince all measured values are compressed to the width of the window, values from self-diagnosis cannot be displayed or recorded during long-term measurement.

Pressing the "Long-term measurement" button takes you to the mask for setting long-term measurement (see fig. 5-19). The "Freeze frame" function is switched on for this purpose. The "Long-term measurement" button remains hidden during the measure-ment. Touch one of the buttons for hours and minutes to select them for setting with the arrow keys. The previously set time is retained for a repetition of the long-term measurement.

Test Instruments


VAS 5051B

VAS 5051

The maximum duration of a long-term measurement is limited by the sampling rate and the number of channels being recorded since as the sampling rate increases, the quan-tity of data also rises. The maximum recording period at a sampling rate of 5 Hz is 48 h.

Fig. 5-19 "DSO" mask with elements for setting long-term measurement

After pressing the "Long-term measurement" button you next set the time for the meas-urement interval. To start the measurement process, deactivate the Freeze Frame but-ton.

The right-hand button decrements the hour or minute by one unit.

The left-hand button increments the hour or minute by one unit.

After pressing the "Long-term measurement" button and setting the time for the measurement interval, start the measuring process by dis-abling the "Freeze frame" button.

NoteDuring the long-term measurement, no USB cables or USB peripheral devices, such as external storage devices, keyboards etc. may be removed or connected. That could result in the loss of data.

Test Instruments


VAS 5051B

VAS 5051

While recording is in progress, the right-hand information window shows the reception time. During this period you cannot change the parametrization of long-term measure-ment but you can abort early by pressing the Freeze Frame button again. The measure-ment result is then displayed as if the time up to that point were actually the time which had been set.

Once the time period has finished, long-term measurement ends. The Freeze Frame function switches itself on automatically and all of the data recorded is compressed to the window width and displayed (see fig. 5-20). This presentation is formatted in such a way that the extreme values of the compressed data are displayed.

At the end of long-term measurement you can evaluate the signal curve with the aid of cursors 1 and 2 (see section 5.4.5.2).

Bild 5-20 "DSO" mask with normal display

You can however zoom in on any section you wish.

Select the section you want to magnify either by tapping at a point on the measurement curve or by selecting a section, dragging it over the screen and releasing it. In the mean-time the start and end of the zoom section are marked by cursor 1 and cursor 2.

The Zoom button is only displayed when no cursor function is active.

Press the Zoom button to zoom in on a section of the recorded data. Pressing the Zoom button again switches the zoom function back off.

5.4.7 Tips and Information

Auto setup - Your most valuable button

The DSO is equipped with an auto setup mode which automatically calculates and makes all DSO settings in response to periodic input signals. If channels A and B and the trigger are correctly selected, after a short time you will get an optimally triggered display which continues in "Auto level" mode.

If no curve is displayed, check why in the following order:

1. Are the DSO leads correctly connected to the tester?For most applications connect the DSO leads as follows:DSO1 lead to input DSO1, DSO2 lead to input DSO2

2. Is the correct channel input selected?For most applications set the DSO for "Channel A" or "Channel B" as follows:Channel A to DSO1 (default), channel B to DSO2 (default)

3. Is the correct trigger channel selected? For most applications set the channel in trigger mode as follows:Channel to DSO1 (default)

4. Repeat auto setup.If possible, auto setup mode with switch to auto level mode is always preferable. Auto setup can also be repeated at any time.

No trigger

In normal and single mode: Triggering will work best when you bring the trigger point onto a clear amplitude value. Use the trigger’s fine adjuster. If the trigger is outside the amplitude, the message "No trigger" appears. Depending on the preconditions, no signal characteristic at all or a frozen signal characteristic (no measurement) will then be dis-played.

Now return the trigger manually to the amplitude range until the message disappears.

Test Instruments


VAS 5051B

VAS 5051

Auto level

In auto level mode you can trigger signals independently of their amplitude and zero position, because then the triggering is based on a percentage amplitude value.

After the auto setup is completed the mode changes automatically to auto level and the triggering is set to 0 % of the amplitude value. In trigger mode you can use the slide con-trol to set any unambiguous trigger value between ± 100%; otherwise the DSO triggers in the middle of the measured signal.

Auto

If you have no information about the signal, use auto mode. In this case, the curve is also output even if the trigger is outside the amplitude (untriggered display).

Afterwards move the trigger manually to a value within the amplitude range for a freeze image.

Normal

Use normal mode if you are familiar with operation of the DSO. You will only get an image when the trigger is within the amplitude range of the measured signal. Make sure there is a valid trigger event.

Single

In single mode you can record a one-off event. The signal is measured and displayed immediately as a freeze frame. Make sure there is a valid trigger event.

5.5 Parallel mode with Test Instruments and Vehicle Self-Diagnosis

5.5.1 Overview

As an option you can run Vehicle Self-Diagnosis and Test Instruments in parallel. Here, in the "Multimeter" and "DSO" masks, in addition to the measured values you can also display the following values which Vehicle Self-Diagnosis reads off cyclically in the back-ground (see fig. 5-22):

• Measurement and status values of the "Final control diagnosis" diagnostic function• Measurement and status values of the "Read measured values block" diagnostic

function• Measurement and status values of the "Basic settings" diagnostic function• Measurement and status values of the OBD functions• Measurement and status values of the LT2 functions• Measurement and status values of the LT3 functionsIn each case up to 4 self-diagnosis values can be displayed. If more values are read out, the first four will be displayed.

Fig. 5-22 "Multimeter" mask displaying measured values from the Vehicle Self-Diagnosis

Test Instruments


VAS 5051B

VAS 5051

After you return to a vehicle self-diagnosis mask, a triggerable configured DSO measure-ment is retained - for example, a single-shot measurement for a valve control pulse. In Vehicle Self-Diagnosis you can then perform operations in the usual manner - in other words, you could press the Continue button, for example, to continue with a final control diagnosis. When you return to the "DSO" mask afterwards, it will now also show the curve which was measured in the background.

5.5.2 Operation

Parallel operation of vehicle self-diagnosis and test instruments is be possible if you switched from "Vehicle self-diagnosis" operating mode to "Test instruments". If Test Instruments operating mode is called directly from the start mask, parallel operation will not be available.

With OBD and LT values you can, if applicable, display the corresponding designator by briefly tapping on the value from vehicle self-diagnosis (see fig. 5-23). Tapping once more on the screen outside the measurement value bar causes the designator to disap-pear again.

While parallel operation is active, you can use the Test Instruments and Vehicle Self-Diagnosis buttons to switch back and forth between the operating modes.

NoteSince the two operating modes do not function synchronously, in the display of the measured values phase shifts will occur, these being caused by the time behaviour of the control units and of the tester operating system. With fast dynamic events the val-ues from Vehicle Self-Diagnosis serve only as additional information and should not be linked with the measured values from Test Instruments in a causal temporal relation-ship.

In the "Multimeter" or the "DSO" mask press the "Meas. values Self-Diagnosis" button. It will not be displayed then in the Test Instruments masks unless you switched over to it from Vehicle Self-Diagnosis.

Test Instruments


VAS 5051B

VAS 5051

You can only end parallel operation and self-diagnosis measurements in "Vehicle self-di-agnosis" operating mode.

Press the "Freeze Frame" button to freeze the measured value dis-play. This pauses the cyclical repetition of the measurement and the last display remains on screen without changing.Press the Freeze Frame button again. The cyclic repetition of the measurement is restarted.The cyclic display of the measured values from the vehicle self-diag-nosis is not affected by the "Freeze frame" function.

In the "Multimeter" or the "DSO" mask press the "Meas. values Self-Diagnosis" button again to hide display of parallel mode. Self-diagno-sis measurements here continue in the background.

5.5.3 Values of "Final control diagnosis" diagnostic function

To display values of the "Final control diagnosis" diagnostic function, proceed as follows:

1. Switch from Vehicle Self-Diagnosis operating mode to Test Instruments operating mode, "Multimeter" or "DSO" mask.

2. Press the "Meas. values Self-Diagnosis" button.3. Switch over to Vehicle Self-Diagnosis operating mode.4. Start final control diagnosis.5. Switch back over to the "Multimeter" or the "DSO" mask. Here the value registered by

final control diagnosis will be displayed (see fig. 5-23).

Fig. 5-23 "Multimeter" mask displaying values from the final control diagnosis

While the display is active you can change back to Vehicle Self-Diagnosis and press the Continue button in order to access the next final control diagnosis.

Trigger conditions cannot be set within multimeter mode. Display is solely the values of Vehicle Self-Diagnosis in parallel with the measured values of the multimeter.

NoteDesignators of values are currently available only for OBD values and LT2 control units.

VAS 5051

5.5.4 Values of the "Read measured values block" and "Basic settings" diag-nostic functions

To display values of the "Read measured values block" and "Basic settings" diagnostic functions, proceed as follows:

1. In Vehicle Self-Diagnosis select a block of measured values (see /7/).2. Switch to the "Multimeter" or the "DSO" mask.3. Press the "Meas. values Self-Diagnosis" button. Up to four values registered cyclically

in the background will be displayed (see fig. 5-22).

5.5.5 Values of "OBD" operating mode

Basically the same rules apply as with displaying values of the "Read measured values block" and "Basic settings" diagnostic functions: A maximum of four values is displayed. In addition the following restrictions apply:

• When more than four OBD values are measured - six PIDs, for example - only the first four values are displayed.

• Only numerical values are displayed.• Only actual values are displayed - that is, no setpoint values are shown (such as min

/ max values).

Guided Fault Finding


VAS 5052

VAS 5051B

VAS 5051

6 Guided Fault Finding

6.1 Overview

This operating mode is not available to the VAS 5053.

The ➚"Guided Fault Finding" operating mode "guides" you from the vehicle identification and detecting a vehicle malfunction (➚fault symptoms) to locating the cause of the fault and finally to eliminating that cause. All the vehicle information (fittings, symptoms, functions and components, documents and function tests) is automatically compiled and made available for this purpose.

All functions from the operating modes "Vehicle self-diagnosis" and "Test instruments" (only VAS 5051 / VAS 5051B) are available in the "Guided Fault Finding" application and are integrated in function tests there.

The fault symptoms are made available to the Guided Fault Finding application from three different sources:

• Fault memory contents (from vehicle systems)• Complaint reports (from user input)• ➚Experience rules (field findings stored in the system)In addition, you have the option of selecting functions or components yourself and incorporating them into the ➚test plan or displaying the documents assigned to them.

The sequence of operations for Guided Fault Finding can be seen in fig. 6-1; this diagram will also direct you to the sections in which the individual areas are explained in detail.

NoteYou can only use the Guided Fault Finding operating mode if at least one brand CD has been installed on the VAS 505x. For information on installing brand CDs, see section 2.5 and section 9.4.3.

NoteGuided Fault Finding only provides limited testing possibilities for old vehicles: the vehi-cle system test for reading the fault memory and also a few customer service functions via the function / component selection. Special fault-finding programs are not provided here.



VAS 5052

VAS 5051B

VAS 5051

(1) Start mask

Guided Fault Finding is initiated from the start mask (for further information, see section 6.2).

(2) Vehicle identification, ➚gateway installation list, ➚basic features

Guided Fault Finding begins with vehicle identification. This can occur either automati-cally, by means of a gateway installation list, or manually, via input of the basic features, or via a mixture of the two (automatic and manual). In some cases, questions can be pre-sented e.g. concerning the national variants. The diagnostic cable must be connected and the ignition must be switched on for automatic and mixed vehicle identification (for further information, see section 6.4).

(3) Vehicle identification, vehicle system test, read fault memory

The vehicle-system test follows once the basic features have been determined and / or input. All the electronic vehicle systems that can be present, given the basic features of the vehicle specified, will be represented in a mask. Vehicle communication will be used to check which vehicle systems and variants are built into the connected vehicle. In addi-tion, their fault memories are be read and their contents displayed once the ➚start mod-ule has finished (for more information, see section 6.6).

(4) Execute start module

Depending on the nature of the diagnostic data, a ➚start module may be run after the vehicle system test. One or more function tests can be started in it, for example, to read out the vehicle identification number (VIN) (for more information, see section 6.6.3).

(5) Fault memory contents

Here the fault memory contents read from the vehicle systems and the associated texts sorted by default by control unit number and fault code are displayed in a mask. If the corresponding ambient conditions are present, they can also be sorted by these (for more information, see section 6.7).

From this mask on you can use the Go to button to switch to function / component selec-tion, where you can select a component yourself, and either enter it in the test plan or display its associated documents.



VAS 5052

VAS 5051B

VAS 5051

(6) Fault memory entries available?

If there are fault memory entries available, the run sequence proceeds to the test plan; if this is not the case, it goes to the "Complaint Report" mask.

(7) Test plan

In the test plan, an automatic test plan is compiled from the fault symptoms that were available and that were entered. The component with the highest degree of suspicion is placed at the very top and is preselected for processing. The results of each function test lead to a re-evaluation of the test plan with a suggestion for the next processing sequence, so the order of function tests suggested can change or others can be added (for further information, see section 6.10).

(8) Function test

A ➚function test starts a function test (test program) that consists of a sequence of ➚test steps, with which it can localise a fault down to the level of an individual component, lead and plug or control unit. The function test's operation is dialog-controlled and uses the full Vehicle Self-Diagnosis functionality e.g. "Read Data Block", "Adaption" etc. With VAS 5051, the internal Test Instruments (multimeter, oscilloscope) are utilised for the function test, e.g. for lead and signal tests.

With VAS 5052, these measurements must be made using external testing devices. The function test dialog boxes allow replacement values to be entered, i.e. you use an external device to take measurements at the measuring points specified and then enter the measured value via a virtual keyboard (for further information, see section 6.11).

(9) Leaving the Guided Fault Finding application

You leave Guided Fault Finding via the "Go to" function. You can "Interrupt" the diagnosis session, "Cancel" it or "Exit" it.

Interrupt

This function permits you to interrupt the diagnosis session briefly (to pause it) or to save the diagnostic session in order to resume it later (for further information, see section 6.12.1).



VAS 5052

VAS 5051B

VAS 5051

Exit

At exit all vehicle systems are checked once again and with faults set the fault memory is cleared and then read again. If there are still faults present, Guided Fault Finding can be continued or be definitively terminated (for further information, see section 6.12.3).

With OBD vehicles when the readiness code is deleted or faulty it can still be generated again via an inquiry.

Cancel

Cancel is like Exit, except here the program goes back to the first Guided Fault Finding mask instead of the start mask.

(10) Executing end module

Depending on the nature of the diagnostic data, an end module may be started before leaving the Guided Fault Finding application. One or more function tests can be started in the stop module, which can be used e.g. for feedback to the vehicle manufacturer (for more information, see section 6.15).

(11) Complaints

If no fault is recognised in the vehicle system test, the Guided Fault Finding application automatically takes you to the "Complaint report" mask. Information about "Technical problem solutions" is available here. In addition, you can enter the complaint lodged by the customer or your own observations. Several symptoms can be registered, in order to establish the ➚fault characteristics as precisely as possible. The tester evaluates the symptoms using the expert knowledge contained on its hard drive (for further informa-tion, see section 6.8).

You can also reach the dialog for entering complaints using the Go to button from the "Test plan" mask (seesection 6.10). This enables you to give the tester additional infor-mation for its fault memory entries.

(12) Function/Component selection

Here, you can directly enter functions or components that, according to your experience, could possibly be the sources of the fault(s). The functions and/or components selected are entered in the test plan (➚User Test Plan) (for further information, see section 6.9). However, you can also select Display Documents via the Go to button and display the documents belonging to the selected component.

If you have problems during a function test, you can use the "Go to" function to save the previous process to a external storage device (for more information, see section 6.3) and pass the information on.

On-line feedback log

An ➚on-line feedback log is available at the end of the diagnosis session for sending feedback to the manufacturer (for further information, see section 6.16).

Operating mode button in the navigation bar

In Guided Fault Finding, you can use the Operating mode button to switch over to the operating modes Test Instruments (VAS 5051 only), Vehicle Self-Diagnosis or Guided Functions, to e.g. carry out a measurement there or a diagnosis function outside of Guided Fault Finding. Functions from Test Instruments or Vehicle Self-Diagnosis that are presently being used by Guided Fault Finding will disappear.

Switching back to the Guided Fault Finding operating mode always takes you back to the mask from which the switchover occurred. Processing of the operating mode can con-tinue unrestricted from that point.

Go to button on the navigation bar

You can use the "Go to" function to interrupt Guided Fault Finding, cancel it, exit it, read ➚ECU identification data, generate the problem log, or switch over to other Guided Fault Finding functions that have already been run (see section 3.3.6 and section 6.3).

Print button in the navigation bar

The following options are also displayed for selection if you have reached the "Test plan" mask:

• Diagnostic log: From the test plan, you can print out a log of all previously run func-tion tests or save it to the removable storage device.

• Function test log: From the test plan, you can print out a log of the last function test run or save it to the removable storage device.

Guided Fault Finding is launched from the start mask. It begins with selection of the brand and the subsequent vehicle identification.

Fig. 6-2 Start of Guided Fault Finding



VAS 5052

VAS 5051B

VAS 5051

6.3 "Go to" destination menu

In the Go to Destination menu ("Go to" button), you are given various options for leaving the Guided Fault Finding application (see section 6.12.) and some administration func-tions (see section 3.3.6).

Using the "Go to" menu, you can however access other functions and masks of the Guided Fault Finding application. It contains the titles of the Guided Fault Finding masks which have already been run, for example, "Vehicle system test", "Fault memory con-tents", "Test plan," and the titles of the test steps already processed in the function test. User-guided masks such as "Complaint report", "Function / component selection", and "Documents" are also contained in the list (for an example, see fig. 6-34). You can return to any of these masks via the "Go to" menu in order to resume Guided Fault Finding at that point.

Under "ECU identification data" you can obtain information about all vehicle systems which have been read as part of vehicle identification.

Example:

019 - Databus OBD Interface4E0910468B 4E0907468Gateway H10 0080Long codingDealership number 12345

01 - Engine electronics4F0910560C 8E0907560 *E5F8C60 H10 ---XE09Coding 5711Dealership number 12345

"Documents" displays only the documents of the last component selected in Function/Component Selection.

If you use a Go to destination (or, where applicable, the "Back" button) to return to a pre-vious test step, you can browse through and have another look at the course of the test up to that point e.g. using the "Continue" button. Existing results and decisions made in test dialogs will be displayed to you. As you go through, you can also repeat and correct measurements and test dialogs. However, from this point on, you must run through the rest of function test as new, since new results and decisions could produce a different program run sequence.



VAS 5052

VAS 5051B

VAS 5051

The "Export problem log" item is another function in the "Go to" menu. If a fault occurs during a function test, you can use this function to save to a removable storage device the run sequence up to that point. Before you save the log you will need to provide via the virtual keyboard a job code for the diagnostic session under which the job can later be found and reloaded. The saved run sequence will show all masks run through in the course of the diagnostic session, and provides additional feedback for the manufacturer. The Guided Fault Finding Light program (not included in the current package) can be used by the manufacturer to import and examine the data.

A removable storage device can hold several diagnosis sessions and screenshots.

You can switch over to other tester operating modes such as "Vehicle Self-diagnosis" and "Guided Functions" via the "Operating mode" button on the navigation bar.

6.4 Vehicle identification

The vehicle identification is for the clear identification of the vehicle by means of basic features (type, model year, variant, engine code) and its control unit equipment as well as other data, such as e.g. the vehicle identification number (VIN).

The basic features can be determined manually via a selection list provided on the tester or automatically. Vehicles with gateway and CAN diagnostics support the identification process, since the gateway provides an installation and status list containing important data for the vehicle identification. In this respect, an identification process for a vehicle with gateway and CAN diagnostics differs from that for a vehicle without gateway and CAN diagnostics.

The following description therefore distinguishes between:

• Vehicle without CAN diagnostics• Vehicle with CAN diagnostics



VAS 5052

VAS 5051B

VAS 5051

6.4.1 Vehicle without CAN diagnostics

After selecting the brand, the basic features are selected and entered manually. The sequence is as follows:

1. Type,2. Model year,3. Variant,4. Engine code.A request to confirm the vehicle identification follows. If there is no connection yet be-tween tester and vehicle, the next picture is displayed and the request to establish the connection (section 6.5). Then, the vehicle system test is performed (section 6.6).

6.4.2 Vehicle with gateway and CAN diagnostics

Provided that communication with the gateway is possible (also see section 6.4.2.2), a message appears:

Communication setup with vehicle systems

The tester reads the installation list and its status information from the gateway control unit and saves it for further evaluation. The installation list indicates e.g. whether a con-trol unit is registered in the gateway (coded) and/or its fault memory is set.

If a non-coded control unit is registered, It can be coded without delay (see section 6.4.2.1). The fault status is used during the vehicle system test, thus allowing the interrogation of the fault memory to be restricted to the indexed control units.

Depending on the brand and the type, an identification test can already take place before selecting the first basic feature (type) that builds on the gateway data already read and further data can be identified, such as e.g. basic features, national variants (about ques-tions) and the vehicle identification number (VIN). In the best case, all basic features can be determined, so that the identification process takes place fully automatically.

If the automatic identification of the basic features is not given, the tester offers the man-ual input of the the non-identified values:

• Type,• Model year,• Variant and• Engine code.The confirmation of the vehicle identification follows the specification of the basic features (see section 6.5).



VAS 5052

VAS 5051B

VAS 5051

6.4.2.1 Gateway not registered

If individual control units are detected as being "not coded" (not registered) when the installation list is evaluated, you will have to recode these control units. Guided Fault Finding automatically activates the "Reading / writing long coding" self-diagnosis function for this purpose.

Fig. 6-3 "Select vehicle systems for coding " mask

Proceed as follows to code:

1. Select all entries marked as "not coded". They change to the "coded" status (registered).

2. Press the Continue button to start coding. Coding is executed in the gateway.The installation list of the gateway is read again and checked for control units that are not coded.

If the coding is once again incorrect, a fault report to that effect will appear. After this you can repeat the coding or press "Continue" to begin manual vehicle identification. You can repeat coding or press the "Continue" button to begin vehicle identification. In this case, the subsequent vehicle system test generates an malfunction message since the gateway was not coded correctly or could not be read. For this purpose,a special communication test, adapted to the gateway, can be presented.



VAS 5052

VAS 5051B

VAS 5051

6.4.2.2 No communication with gateway

If the tester was unable to set up communication with a gateway control unit, it will present you with the manual vehicle identification option. Here, select the vehicle's basic features one after the other from selection lists that you are shown. The previously selected basic features will appear in the right-hand information window of the following masks, for verification of the selection made.

After selecting the fourth basic feature, the "Check vehicle identification" mask appears. At any time, you can switch back to the previous screen using the "Back" button to make a different selection there. The next mask shows the next picture (see section 6.5). If you now press the "Continue" button, the tester attempts to establish communication with the gateway again. If this does not work again, the following note appears:

Fig. 6-4 Note: "No CAN communication possible"



VAS 5052

VAS 5051B

VAS 5051

6.5 Confirming vehicle identification, diagnostic connection

The following mask concludes vehicle identification. The basic features specified are shown in the right-hand information window. Check carefully whether the vehicle to be diagnosed matches the entries exactly. With manual vehicle identification, you can press the "Back" button to switch back to the previous masks to make changes there if neces-sary.

Fig. 6-5 "Confirm vehicle identification" mask

When you press the "Continue" button, the diagnostic data for the specified vehicle is loaded from the hard drive into the working memory and communication with the vehicle is established.

If you have not yet connected the diagnostic cable with the vehicle, you will be prompted to connect it after confirmation of the vehicle identification. To do so you will be shown a document displaying the fitting location of the diagnostic connection.



VAS 5052

VAS 5051B

VAS 5051

If you press the "Continue" button, the tester attempts to establish communication with the vehicle again. You can repeat the communication setup any number of times or can-cel it if you are unsuccessful continuously. In either case, the tester switches to the vehi-cle system test.

If communication could not be established during CAN diagnosis, the tester sets a special communication test in the test plan without previous vehicle system test (see section 6.4.2.2).

6.6 Vehicle system test

The vehicle system test checks whether electronic vehicle systems are present in vehi-cle and whether they have any saved fault entries. If automatic vehicle identification was possible via a gateway control unit, the list of possibly installed systems is compared with the coding of the gateway control unit as follows:

• Systems shown in the gateway control unit as installed and which have no fault status are accepted without further checking.

• The fault memories of systems shown with a fault status are read out and the contents saved in the tester.

• Systems entered in the gateway control unit as not being installed are nonetheless checked to see if they are present and whether they have a fault status.

In vehicles without a gateway, checks will be carried out generally for the presence and fault status of all possible systems and their variants.

In the "Vehicle system test" mask (see fig. 6-8) the vehicle systems that may be installed in the identified vehicle are classified in the following groups:

• Powertrain (gateway, engine, gearbox)• Suspension (brakes, distance control, self-levelling system, ...)• Body (dash panel insert, immobiliser, heating, ventilation,

air conditioning, ...)To make the layout clearer, the systems in the individual groups are set apart from one another in the mask by different background colours and a separating line.

You can observe the progress of the vehicle system test on the touch screen. The system currently being interrogated is marked with an arrow on the right in the work window. Identified vehicle systems are marked with a black bar and the colour of the let-tering is inverted. The status of the vehicle system is entered in the column on the right (see table 6-1).

The vehicle system test works through the vehicle systems from top to bottom. Vehicle systems are skipped if they are mutually exclusive with one that has already been identified.

If a control unit contained in the selection list was not identified, e.g. because it was defective, you should select it manually (see section 6.6.1.2 and section 6.6.1.3). Its cor-responding diagnostic data for "Guided Fault Finding" is only made available if this is done. For vehicle systems safely installed in the vehicle (standard fittings for the series), a corresponding message appears stating that the system could not be identified. For vehicle systems "definitely installed" in the vehicle (standard fittings for the series), a cor-responding message will appear saying that the system could not be identified.

After the test has been carried out, the following message will appear in the information field on the left of the mask:

Control units have been interrogated

6.6.1 Possible problems

6.6.1.1 Diagnostic bus faulty

This message (fig. 6-7) appears in the following cases:

• The diagnostic cable is not connected either to the tester or to the vehicle, or the con-nection has come loose at the vehicle end.

• The battery voltage from the vehicle is in a range critical for the tester (see /3/, section entitled "Technical data"). In this case, start the engine or use a battery charger. You can then repeat the communication attempt.

• The diagnostic bus or cable is defective. Perform the self-test (see section 9.6).

If you press Cancel, the vehicle system test will be ended.



VAS 5052

VAS 5051B

VAS 5051

6.6.1.2 Definitely installed control unit not recognised

If communication is not possible with a definitely installed control unit, its entry in the list will not be marked and the following message will then appear:

Communication withdefinitely installed control unitis not possible!

Repeat Cancel

If communication is not possible after "Repeat", select Cancel.

You will be given the following message:

Cannot recognise control unit.

To enter it as installed anyway,press "OK".

Select "OK" so that the data applicable to that definitely installed control unit (➚diagnosis objects) will be available.

6.6.1.3 Optionally installed control unit not recognised

If an optionally installed control unit could not be identified, its entry in the list will also not be marked. No message will appear to indicate a non-recognised system.

Check whether optional vehicle systems are installed in the vehicle to be diagnosed and select them as required manually. That is the only way to guarantee that you will be shown the diagnostic data applicable to the vehicle in later masks, in particular in Function/Component Selection.

NoteIf all control units have been interrogated, you must manually select the "Definitely installed control units" afterwards in the "Vehicle system test" mask. Only this ensures that the corresponding diagnostic objects are visible in the functions / components selection.

While the vehicle system test is running, all buttons on the navigation bar will disappear except the "Help" and "Warnings / notes" button.

After the vehicle system test has been carried out, you can navigate using the "Continue" or Go to buttons.

Pressing the Continue button will take you into the start module if it is available, or to the "Fault memory contents" mask (see fig. 6-9).

The Go to button in this mask makes it possible to access the "Function/component selection" mask for the first time (see section 6.9).

6.6.3 Start module

The start module can run automatically in Guided Fault Finding after vehicle identification and before the fault memory entries are displayed. It can contain one or more function tests running separately to the test plan and not entered in the test plan. In this way, it reads e.g. the vehicle identification number (VIN) or checks the software status (flash status) of control units. In some cases, the start module can also request this data from you.

After the start module is closed, processing continues with the "Fault memory contents" mask. Function tests in the start module are listed in the diagnosis log.

6.7 Fault memory contents

The "Fault memory contents" mask informs you of faults with possible ambient conditions in the electronic vehicle systems. If no fault was detected, the following text will appear in the information window on the left:

no fault recognised

If faults have been detected, they will be sorted by vehicle system and fault code in ascending order ("Standard" sorting).

If a fault (fig. 6-9, fig. 6-10) has been displayed, you are taken to the "Test plan" mask when you press the "Continue" button (see fig. 6-25), otherwise you are taken to the "Complaint report" mask (see section 6.8).

Fault memory contents and their correlations

Fig. 6-9 "Fault memory contents" mask: "Standard" sorting

The scope and structure of the displayed data depends on the build status of the control unit. One by one:

• Number of faultsThe number of fault memory entries read appears at the top in the right-hand informa-tion window.

• Fault codeExample:19461 P3005 035 001 NoteThis is a five-digit fault code followed by an SAE-standard code number, fault type 1, fault type 2 and the possible indicator "Note". Not all blocks are output with every fault code.



VAS 5052

VAS 5051B

VAS 5051

• Fault code / fault locationThe five-digit fault code indicates the location of the fault - for example "Relay for high heating output - J360".

• SAE numberA code number according to the SAE standard can be assigned to the fault code.

• Fault type 1The three-digit fault type 1 describes the fault symptom more closely - for example, "Short circuit to earth", "Implausible signal", "Lower limit fallen short of", etc.

• Fault type 2Fault type 2 describes how the fault manifested itself - for example, "statically" or "spo-radically". If the mask does not show an entry for fault type 2, this means the fault type is "static".

• NoteThis fault memory entry does not indicate a fault but rather a note.

You can change the fault code sequence by pressing the corresponding sorting buttons. With all types of sorting faults without a sorting criterion will appear at the end of the list, sorted by control unit and marked by a violet background.

There is one special feature to note when sorting is on the basis of the time stamp. Faults which follow another fault within a particular prespecified time span (1 minute, for example) are grouped together and shown with a light blue background. This aims at showing faults and their consequent faults in context. Notwithstanding this, all faults will still be sorted in ascending time order.

Fig. 6-10 "Fault memory contents" mask: "Time" sorting



VAS 5052

VAS 5051B

VAS 5051

If you press the Ambient conditions button the fault memory entries will be displayed indi-vidually with their corresponding ambient conditions. Depending on the vehicle system these could be standard values and expanded ambient conditions in the form of mea-sured values.

Fig. 6-11 "Fault memory contents" mask: "Standard" sorting (without measured values)

The following ambient conditions can be output:• Standard values (when provided)

The following ambient requirements are grouped under this:− Date, time: Time stamp at the time when the fault was detected.− Odometer reading (mileage): Shows at what odometer reading the fault was de-

tected.− Priority: The priority can have a value between 0 and 15:

0 - 5: fault ID with descending priority; 5 = fault with lowest priority6 - 8: note, no fault.

− Malfunction occurrence counter: The counter can have a value between 0 and 254. Every time the fault occurs (through all driving cycles) the counter is incre-mented by 1.

− Unlearning counter / driving cycle: Indicates the current counter status of the ➚unlearning counter. When a fault occurs, the unlearning counter is set to a con-trol-unit- and fault-code-specific value - for example, 40. If the fault does not occur during the next driving cycle it is marked as "sporadic". Every subsequent driving cycle without a fault decrements the unlearning counter by 1.



VAS 5052

VAS 5051B

VAS 5051

• Measured values (when provided, additional ambient conditions)Measured values can also be displayed exclusively or additionally for the individual fault codes. The ambient conditions (which may number up to eight) can in each case consist of a default value and up to seven measured values, or up to eight measured values without a default value.

You can control the display via the buttons on the right-hand part of the work window:• Position

The first fault in the list displayed together with its ambient conditions takes the 1st position. You can navigate between the faults by means of the two arrow keys.

• SortingWhen the mask opens, the setting is always "Standard". With the displayed buttons you can however switch sorting over to different criteria:

Sorting by standard:When you press the "Standard" button the faults are sorted in ascend-ing order by:• Fault code• Time• Odometer reading• Priority• Frequency of occurrenceSorting by odometer reading:When you press the "Kilometer" button the faults are sorted by the odometer reading, starting with the lowest. Fault codes without kilo-metre indication appear at the end of the list in the order in which they were read from the fault memory.Sorting by static / sporadic:When you press this button, first the static faults are displayed sorted and then the sporadic faults.In the static faults group, the tester sorts by the change frequency of the malfunction occurrence counter starting with the lowest value (fault hardly changed to sporadic - in other words, behaves virtually statically). With sporadic faults sorting begins with the highest value.Faults which appear in the malfunction occurrence counter are fol-lowed by faults not in the counter or with a value of "0".Sorting by time:If you press the "Time" button the faults are sorted by the time stamp, starting with the earliest. Fault codes without a complete time stamp (date, time) will appear at the end of the list in the order in which they were read from the fault memory.

Note about ➚➚➚➚ASAM-ODX control unitsThe previous examples apply to control units with ➚KW1281/2000/6000 protocol. Under ASAM-ODX there is only the 2nd fault type. Appropriate contents of fault type 1 are already included in the fault code / fault location. Usually, only the SAE code is displayed as fault code on the tester.The ambient requirements displayed may also differ here.

6.8 Complaint report

The "Fault memory contents" mask (see fig. 6-9) is automatically displayed if no faults were recognised in the vehicle systems and you then pressed the Continue button. Entering complaints is another option for entering fault symptoms.

The "Complaint report" masks contain predefined lists of terms from which you can select the complaints reported by the customer or observed by you yourself. You can input several complaints from each of the two groups, "Technical problem solution" and "Repair group". The groups differ in the following way:

• Technical problem solution: Here the complaints are sorted by solutions to the prob-lem behaviour as currently known (function, fault number, and so on).

• Repair groups: Here the complaints are sorted by vehicle structure and the symptoms you have noticed (drive, engine, performance, and so on).

You should enter as many of the known fault symptoms as possible in order to describe the complaints. You can also enter complaints if there are already entries in the fault memory. You can reach the input screen for complaints by selecting the "Complaint report" item in the "Go to" menu.

You can select one element from the lists of terms on each mask. As each term is selected, it is immediately accepted and the screen switches to the next mask. You can use the Back button to jump back to the previous mask at any time and change the selection on that mask. The steps selected are displayed one after the other in the infor-mation window on the right-hand side of the masks.

If the "Overall selection display" mask appears, you can accept the new selection and select the already existing one for deletion. Only complaints appropriate to the vehicle will be presented for selection.

You do not always have to specify something at all levels of a given complaint. As soon as the Continue button appears, you can switch over to the "Overall selection display" mask (see fig. 6-14). In this case all of the syptoms coming under the step last reached will be included in the test plan.

By pressing the Continue button, you will leave the "Complaint report" function and switch over to the "Test plan" mask. As you switch over, the tester will prepare the test suggestion that matches the symptom and will enter it in the test plan.

If suspect components have already been entered in the test plan, a Yes/No question will appear to ask whether you want to replace the current system test plan with a new one. Select "Yes" to enter the suspect component that matches the complaint into the test plan.

6.9 Function/Component selection

The "Function/Component selection" function gives you the option of applying your own personal expert knowledge in the context of Guided Fault Finding. Here, in contrast to the evaluation of fault memories (see section 6.7) or complaint reports (see section 6.8), you directly select functions or components that seem suspect for testing.

In addition to function tests, other functions, documents (see section 6.9.1) and informa-tion may also be stored here, which do not belong to the fault finding, such as e.g.:

• Customer service functions (coding, reading measured values, ...)• Information / documents on testing equipment, tools• Information on fuse / relay configuration

After the functions and/or components are selected, the tester automatically allocates the relevant function tests to them. In this way, you compile your own "User test plan". The names of the selected functions or components appear in the "Test plan" mask under "User test plan" (see section 6.10), if there are already system-guided test sug-gestions available. This is presumed for the example which follows.

The "Function/Component selection" mask is accessed from the "Vehicle system test" mask by pressing the Go to button. Function, repair group, component group and com-ponent are selected from lists displayed over several masks, similar to the procedure for the complaint report (see section 6.8).

When selecting functions and components, the screen layout develops in the form of lev-els, with each level distinguished by an indent to the right when compared with the previ-ous item selected. If a row is proceeded by the "+" symbol, this indicates further options for selection. Example:

+ Powertrain+ ADR engine

+ 01 - Systems capable of self-diagnosis

+ Electrical componentsetc.

NoteThe only functions and components definitely displayed are those for vehicle systems marked in the "Vehicle system test" mask (fig. 6-8), i.e. those that were automatically identified or manually selected.

+ Motronic engine management system



VAS 5052

VAS 5051B

VAS 5051

Each indent signifies a selection in a mask. If you want to jump back one level, select a higher level (not the Back button since this takes you directly back to the test plan!). Example:

+ Powertrain+ ADR engine

+ Motronic engine management system

Example of a "Function/Component selection" mask sequence:

Fig. 6-18 "Select function or component" mask, 1st level

Select "+ Drive", for example. The next mask will be shown automatically when the selection is made. Specify the function or component in more detail in the masks which follow. If you want to change your selection, touch the preceding selection.

6.9.1 Documents

Available documents, such as installation locations, pin assignments and so on, can be selected and displayed in the "Function / component selection" mask. For this purpose, select the relevant function / component and then the Go to destination "Documents". After the first selection, the Go to destination "Documents" is available for selection per-manently in the Go to Destination menu.

Documents (graphics, text) are displayed in the work window. If they are larger than the work window, they will be provided with a vertical scroll bar.

Documents are also found in the function test masks. There they are made available directly via a row of up to six numbered and correspondingly labelled buttons (see section 6.11.1).

Example of a mask sequence arising from "Function/Component selection":

Fig. 6-22 Function/Component selection, "Documents" selected as "Go to" destination

You can activate the "Select document" dialog box for a selected function or a component via the "Go to" destination menu.

NoteIf you selected a diagnosis object in function/component selection, you can also access its documents directly by selecting "Documents" from the "Go to" menu during the ongo-ing function test. The documents presented here do not form part of the current function test, but rather the last selected function/component selection.

6.10 Test plan

When the transition is made to the "Test plan" mask, the results of the previously run "Fault memory contents", "Complaint report" and "Function/Component selection" masks are evaluated, and a test suggestion is created from that and shown as a list (see fig. 6-25). The priority of the tests is expressed in their sequence. In the actual example, the contents of the fault memory lead to a test suggestion that is entered in the test plan and preselected there. Pressing the Continue button will begin the marked function test.

Fig. 6-25 System test plan and user test plan with several suspect components

The test plan shows one or several symptoms (blue font) above the suspect module or function (diagnostic object). The diagnostic object is preceded by a status (see table 6-2). If you select it and press "Continue", an appropriately linked function test is started. Afterwards, the status of the diagnostic object is updated. In addition, the function test can enter new diagnostic objects in the test plan or set existing ones to "OK". Diagnostic objects entered in the test plan by a function test, appear directly under the previously selected diagnostic object - slightly to the right.

You do not always have to adhere to the suggested sequence of the function tests. Rather, you can deviate from it at any time and select a different test in the automatic or user test plans (included via the functions / components selection, see section 6.9) as the next function test.

VAS 5052

VAS 5051B

VAS 5051

The "static" or "sporadic" (fault no longer present at the moment) fault type plays a role for the sequence of the diagnostic objects. If only sporadic faults are assigned to a diag-nostic object, they are placed at the end of the test plan. When you start the function test of such a diagnostic object, the following message may appear:

Sporadic faults occurred.(possibly additional text)

Would you like to see the details?

If you confirm with "Yes", the corresponding fault memory entry is displayed along with the ambient requirements (if available).

When all the function tests for the diagnostic objects entered have been performed, the test plan is considered to have been processed. You can also repeat function tests by reselecting the diagnostic object and pressing "Continue".

The status preceding the diagnostic object corresponds to the current status of the func-tion test or the result of the linked function test.

"OK" means, for example: the function test was performed without any faults; the diag-nostic object (module or function) is OK.

Table 6-2 Meaning of symbols for the status of the diagnostic objects

Symbol Meaning: function test

- Not yet carried out

OK OK

OK! This status is a special case: A function test may end with the status "Diagnosis generated and component repaired". In this case, the tester does not go back to the test plan after completing the function test, but asks the question:

Repeat test after repair is completed?

If you answer with "No", the status "OK" (already repaired, result not checked) is entered in the test plan in front of the diagnostic object. If you answer with "Yes" instead, the function test is repeated in verifica-tion mode (examination of the repair). However, this concept requires appropriate program components in the function test, e.g. a short test. If these program components are not available, the entire function test is repeated and the reaction is the same as during the initial activation.You can also start the verification of a function test from the test plan by the repeated selection and start the "Test" selection.

OK? Probably OK.It is not possible to make a statement with 100 % certainty about the result of a particular function test, since e.g. not all the results are testable.

6.11 Function test

A defined function test has been assigned in the test plan to every vehicle function, every component group and every component (diagnostic object that could indicate a fault). Its task is to test the requirements defined for each. It yields the results "OK", "Not OK" or "Test result unknown".

A mask from a function test is shown in fig. 6-26. Every function test consists of a num-ber of self-contained test steps which can also be repeated via the "Go to" menu after they have been executed. The information window on the left contains the title of the function test, while the name of the test step currently being processed is displayed as a heading in the work window.

A function test can include the tester's communication via the diagnostic bus, as well as measuring instructions. You become actively involved in the process at this point, e.g. to connect measuring leads, to make decisions or to enter values. For this purpose, the tester will provide you with up to two rows of appropriately labelled buttons in the work window, for example. The left row contains the buttons for further processing of the test dialogs (see section 6.11.1); the right row contains up to six numbered buttons for displaying documents.

After the function test is finished, the tester will return to the "Test plan" mask. There, you can select the next diagnostic object and start its function test or access alternative diagnostic procedures via the Go to Destination menu (such as complaints or function/component selection).

NoteSince, unlike the VAS 5051 / VAS 5051B, the VAS 5052 does not have any internal test-ing devices (e.g. multimeter, oscilloscope) external testing devices must be used and measurement results transferred to the function test via replacement value input.



VAS 5052

VAS 5051B

VAS 5051

In this example of a function test, a question appears after starting:

Fig. 6-26 Function test, question to the user

Different masks appear later in the course of the function test depending on the actual tests done, e.g. a message with the Done button:

VAS 5051

Select the "1. Fitting location" button, for example. You are immediately shown the matching image document (see fig. 6-28).

Fig. 6-28 Document display, "Fitting location" example

Use the Back button to switch back to the previous mask, and use the Done button to continue the test there after dealing with the message.

One element of the function test shown in the example is a resistance measurement. The corresponding mask (see fig. 6-29) contains instructions as to which measuring points the measuring lead should be connected to. Press the "Measure" button to start the cyclic measurement on the VAS 5051 / VAS 5051B. If you press the "Measure" but-ton again, the value last measured is retained. Press "Continue" to continue the function test. You can also use this button to cancel an active cyclic measurement directly and continue the function test with the value last measured.

NoteThe button on the probe tip triggers the same function as the "Measure" button on the screen. It is recommended to use it if the tester screen is not visible or accessible from your working position on the vehicle.

Replacement value input

If no measurement is possible or if an external testing device must be used for the meas-urement (VAS 5052), you can enter the value manually. To do so, touch the results field (fig. 6-29). A numeric keyboard will appear for entering replacement values. On the VAS 5052, the virtual keyboard also appears after the Measure button is pressed.

Fig. 6-30 Virtual keyboard for entering measured values

Enter the measured value. The "Q" button is for applying the value you entered.

6.11.1 Test dialogs

In the function test, you will find the following types of user/test dialogs:

• Messages to the user with the Done button for continuing with the program.• Questions to be answered with the buttons "Yes", "No" or the additional button

"Unknown".• Decisions with up to eight buttons for branching off on separate program paths.• Measuring instruction with the Measure button for starting and/or stopping the cyclical

display for the measured value.• Displays of results from a control unit with the Read button for starting and/or stopping

the cyclical output of those results.• Displays without a special button for cyclical program runs (loops) and for any cyclical

output of texts or values. A cyclical loop is interrupted either by the test program or by pressing a button.

• Input instructions for entering a numerical value or text via a keyboard that appears on the screen.

All test dialog steps are only concluded when a button appropriate to the activity is pressed, e.g. "Done", "Yes", "No" etc.

All test dialog steps can include buttons for displayable image documents. They are dis-played by pressing the corresponding button, switching to the document display and then back to the test dialog step.

6.11.2 Measuring instruction (multimeter)

The work area of the "Function test, G62 - Sender for coolant temperature" mask (see fig. 6-29) contains a display of the type of measurement ("Resistance measurement"), the instruction for connecting the measuring lead, an optional description of the mea-surement ("Resistance measurement on sender for coolant temperature (G62)"), and the specification of the target value and the measured value as a bar display and as a numerical output.

The bar display contains a numbered scale. A rectangle indicates the range of tolerance for the measured value. The measured value appears as a coloured horizontal bar on the numbered scale. If the value is OK (green), the bar will jut into the tolerance window. A red bar indicates an incorrect measured value; the display "+++++" indicates an over-load.

The numerical display also includes the physical unit of measurement.

Measurements of numerical values are triggered by pressing the Measure button after the specified connections have been set up.

The measurement is repeated several times in a cycle, as long as the "Measure" button is pressed; the last value measured is accepted after the "Continue" button is pressed. Pressing the Measure button again stops the continuous measurement, and the last value displayed will be kept.

The Measure button can alternatively be activated via the switch in the red probe tip.

If the internal testing device is defective or if you prefer a testing device of your own, you can enter the measured value thus determined via a keyboard on the screen. The key-board appears automatically when the results field is touched or if the internal Test Instruments are malfunctioning. It will disappear again after entries have been made when the buttons Q or Continue are pressed, or, if a genuine measurement is carried out, by pressing the Measure button. The physical unit for the entry (e.g.: V, mV) is pre-set automatically.

VAS 5052:

Here, a numerical keyboard appears when the Measure button is pressed, for entering a measured value.

6.11.3 Measuring instruction for vehicle systems

The vehicle systems supply a wide variety of measured values relevant to diagnosis which can be interrogated and evaluated in a function test by so-called "measuring instructions". In some cases measuring results are displayed in a message (fig. 6-31) or directly from the measuring instruction.

Measuring instructions to vehicle systems require functioning communication with the ve-hicle system in question.

6.11.3.1 Measuring instruction results in a message

As a rule measurement results are displayed in messages. Here the measuring instruc-tion itself runs invisibly in the background.

Fig. 6-31 Function test, message with measurement from vehicle system

fig. 6-31 shows a message which is incorporated in a loop in the function test. Every time the loop runs, the measured value is read from the vehicle system and updated in the mask. It is not possible to input a replacement value here.



VAS 5052

VAS 5051B

VAS 5051

6.11.3.2 Measuring instruction with direct output

In some special cases measuring instructions with vehicle systems are also programmed as direct output. The display is similar to the measuring instructions for multimeter appli-cations (see fig. 6-29), but with the following differences:

• Since it only uses internal measurements of the vehicle systems, it can also be ac-cessed on the VAS 5052 without restrictions.

• Instead of the Measure button a Read button is displayed. If vehicle communication is possible, while it is activated the selected measured value is displayed cyclically in the result field.

If vehicle communication is not working, you can input a replacement value manually. Touch the result field (see fig. 6-29) to access the virtual numerical keyboard and input the replacement value. Next press "Continue". The Read button is not used in replacement value input.

6.11.3.3 Measured values table

This provides another way of displaying measurements from vehicle systems. The func-tion test can present you with a measured value list for selecting measured values or a preselected selection of measured values for displaying the results.

Selecting measured values from a measured values table

This display allows you to select the desired measured values yourself from a measured values table. The display groups are given different coloured backgrounds to make it easier to differentiate them. Each entry consists of a group number, the number of the display field (not with ASAM-ODX) and the measured value name.

The measured values of different control units are given different colours to make it eas-ier to differentiate them.

After selecting at least one measured value, press the "Ready" button which takes you to the next mask where you can perform the measurement.

Carrying out measurement

You can go to this mask directly from the function test or via the selection list of the measured values table (fig. 6-32). There can be any number of measured values. The "Result" column initially is empty. Press the Read button to read the measured values cyclically from the vehicle system(s) (fig. 6-33).

Selecting individual measurements

You can select a single line. With this, the name of the measured value and the result are displayed again in the long information bar in the lower part of the work window. At the same time, a "Message text" button and/or a "Test program" button may appear on the right (not illustrated).

• Message text: Information about the measured value is provided here.• Test program: If a result is outside the specified value and you select the relevant

measured value, a function test for finding faults may be offered when you press the "Test program" button. If you press this button, the function test is entered in the test plan; an appropriate message is displayed. You can activate this test after the current test.



VAS 5052

VAS 5051B

VAS 5051

Press the "Go to" button to jump back to the selection list "Measured values:Read meas-ured values"where you can make another measured-value selection. Press the Continue button to continue with the function test. In some cases the measured values table is quit automatically - such as when, for example, all values are OK.

Fig. 6-33 Function test, measurement in progress

NoteThe display frequency of the results corresponds to that in Vehicle Self-Diagnosis if the measured values to be displayed belong to a display group. Displaying measured val-ues from different display groups and control devices will have a negative effect on time behaviour and synchronization.

6.11.4 Digital Storage Oscilloscope (DSO) measuring instruction

VAS 5051 / VAS 5051B:

The DSO measures graphical curved lines cyclically using parameters preset by the function test and displays them. Press the Freeze Frame button to pause the cyclical repetition of the measurement. The last display will freeze on the screen. Press the Freeze Frame button again to start the cyclical repetition of the measurement up again. The "Freeze frame" button can also be operated by activating the switch in the red probe tip of the measurement cable.

With measurements that are triggered by a particular condition (i.e. events), the Measure button is used to enable triggering. The measurement is then automatically initiated when the trigger event occurs.

The measurement instruction is followed by a question regarding the evaluation of the signal curve.

VAS 5052:

A DSO measurement must be carried out using an external device.

6.11.5 Cancel function test

Normally, you can only move from the "Function test" mask to the "Test plan" if all operator entries have been properly concluded and a clear test status has been achieved. Missing information or operator actions that are still outstanding are displayed via messages.

Nonetheless, you can cancel an ongoing function test in the following way:

1. Use the "Go to" destination menu to switch over to the "Test plan" mask.2. There, select the ongoing function test and press the Continue button.3. In the dialog which appears, press the "Abort function test" button. Note that the status

6.12.1.3 Load diagnosis job

You can reload saved diagnosis jobs in the masks of the basic features (type, model year, body version, motor). To do so, select the "Diagnosis job" function in the "Go to" destination menu. Choose the desired job and select "Edit". An instruction follows with the job name and the corresponding vehicle that must be connected. When you acknowl-edge the instruction with "OK", the "Test plan" mask will follow. It shows the status achieved for the interrupted diagnosis job when it was saved.

After the saved diagnosis job is loaded, the saved item will be deleted. Therefore, you should save the diagnosis job again if you need to, in which case it will be stored again under the same name.

Example for a "Load diagnosis job" mask sequence:

Select "Diagnosis job" as "Go to" destination:

6.12.2 Cancel

The Cancel function corresponds to the Exit function with the difference that you return to the basic "Select brand" mask of Guided Fault Finding. In other words, you remain in the Guided Fault Finding operating mode. With Exit, the Guided Fault Finding operating mode is exited and you go to the start mask.

6.12.3 Exit

You can leave Guided Fault Finding using the Exit destination in the "Go to" destination menu. A question appears with information for exiting and the answer options "Do not exit", "Diagnosis log" and "Exit".

Select "Do not exit" if you want to continue working instead. Select "Exit" to initiate the return to the start mask. All operating modes will be closed.

Before returning to the start mask, all vehicle systems identified will be tested again by a system test. If there are faults set, the fault memories will be erased and then read out again, to display any static faults that may be present.

If there is still a fault memory set, the following message appears:

All fault memories have been erasedHowever, relevant faults are still set or have been set again.

Therefore, if you want to restart the "Fault memory contents" mask,press "OK".

If you still want to cancel or exit,press "Cancel".

You now have the option of continuing with Guided Fault Finding or of exiting the pro-gram. Before you really do quit, a stop module (if present) will also be started (see section 6.15) and you will be asked if you wish to print the diagnostic log.

OBD vehicles

In the case of OBD vehicles the readiness code will be checked after the system test or before the stop module runs. If this code is deleted or incorrect, how next to proceed is dealt with in the case examples:

Example 1: Faults were set in the engine control unit

When the fault memory was erased, the engine control unit's readiness code was also erased. The following message then appears, with a Yes/No question:

The readiness code has been erased. Do you want to generate the readiness code again now?

If the answer is "No", the readiness code remains erased. If you select "Yes", the function test for generating the readiness code will be started.

After the function test has ended, it will be entered with a status symbol in the "User test plan", which will then be displayed. You now have the option of continuing with Guided Fault Finding or of cancelling it again via "Go to/Exit".

The readiness code query will only be shown if there is a corresponding function test available for generating the code.

Example 2: No fault set in the engine control unit

When diagnosis is exited, the engine control unit's readiness code is interrogated. If it is not OK, a note appears with the question:

The readiness code is not OK. Do you want to generate the readiness code again now?

If the answer is "No", the readiness code remains unchanged. If you select "Yes", the function test as per Example 1 for generating the readiness code will be started.

NoteCurrently, the readiness code is only evaluated for an engine control unit.

6.13 Diagnosis log

If you have accessed the "Test plan" mask at least once, you can use the "Print/diagnosis protocol" function to print out a Guided Fault Finding protocol or save it to an external storage device. In the latter case, you must enter the vehicle ID number and the license plate number in the print menu, provided the data is not already known from the diagnostic procedure. For printing, refer also to (see section 3.5).

Prior to the actual output, you are asked whether you would like to output the diagnostic protocol in short or in complete form.

The "Diagnostic protocol" function is also offered after the end of the stop module by means of a dialog box.

The complete diagnostic protocol contains the following information:

• Workshop code, dealership identifier• Version of the currently installed software system (base CD, brand data and vehicle

project name / version of the ODX run-time data for ASAM-ODX control units)• Licence plate number and vehicle ID number, if available• Vehicle brand and identification characteristics (➚basic features)• Time required for diagnosis in VW units of time (➚time record for the diagnosis ses-

sion, derived from the sum of fixed values and actual time required)• Event memory: List of the detected vehicle systems, their identification data and fault

status. If there is a fault, also their fault memory contents with possible ambient re-quirements

• Work steps performed (list of the main actions in running order), such as:beginning of diagnosis, vehicle identification, vehicle system test (selection), vehicle system test (performance), event memory (fault memory contents), test plan, function tests1 including start and stop modules, beginning and end of an interruption (saving and loading of a diagnosis session)

• Numbered test plans corresponding to the work steps, each subdivided into system test plan and user test plan (where these exist)

• Function tests that have been carried out, numbered according to the work steps listed. The title of a test according to the test plan can be taken from the work steps. All test steps run will be logged, with message output, results and dialog decisions. The communication jobs with control units and their results will be listed under "Diagnosis". The sections "Beginning sub-function: …" and "End sub-function: …" show subprograms loaded during the function test.At the end of a function test, the full results will be displayed according to the test plan, e.g.: "Function test OK".

VAS 5052

VAS 5051B

VAS 5051

• Malfunction messages of the run-time system are listed together at the end of the pro-tocol. Messages that were generated during the processing of the test plan are listed under "Diagnosis job".

Short form

The short diagnostic protocol does not contain any list of the test plans and function tests.

6.14 Function test log

The "Print/function test protocol" function corresponds to a different short version of the "diagnostic protocol". The list of work steps and test plans is left out and only the last func-tion test carried out is logged.

6.15 Stop modul

The stop module is automatically started when you quit the Guided Fault Finding applica-tion and can contain one or more function tests (also see section 6.1).

Once the stop module has finished and before the diagnostic session finally terminates you will be asked whether the diagnostic log should be output. The diagnostic log thus out-put also includes the progress of the stop module function test.

VAS 5051B

VAS 5051

6.16 On-line feedback log

During a function test or in the stop module of the Guided Fault Finding application and depending on the vehicle and manufacturer, a diagnostic protocol or a fault protocol may be sent to the vehicle manufacturer. The tester must be connected to your workshop net-work for this function.

The online feedback protocol can contain data such as the number of the vehicle (VIN), the number of the tester (equipment no.), the dealership identifier and the fault memory contents read out for all control units. Questions may also be displayed, e.g.: "Was the repair successful?"

If the tester is not connected via the VW workshop network, you need to enter the login for the online connection.

Aborted or unsent online feedback protocols are kept on the tester for up to forty days. On starting, the tester checks whether protocols have been saved and whether there is a net-work connection. If that is the case, the tester offers to send the saved protocols now.

7 Guided Functions

7.1 Overview

Some function tests correspond to vehicle-specific, customer-service-oriented tasks, such as adaptations, coding, and so on. The Guided Functions operating mode allows you to access these tests directly, after vehicle identification (without always having to run the vehicle system test). Fault-finding programs are not provided here, start and stop modules do not run.

These tasks can also be accessed in Guided Fault Finding after the vehicle-system test and selection of function / component selection.

The run sequence described in the following is depicted in fig. 7-1.

(1) Start mask

Guided Functions is launched from the start mask (for further information, see section 7.2).

(2) Vehicle identification, ➚gateway installation list, ➚basic features

After activating the Guided Functions, you must enter the brand and the vehicle identifi-cation (type, year of manufacture, variant and engine code (basic features)) as in the Guided Fault Finding, and confirm them. Depending on the type of vehicle, automatic or mixed vehicle identification of the basic features may be possible.

(3) Display vehicle systems

The vehicle systems for which Guided Functions are available will be displayed.

(4) Select vehicle systems or function

Select the desired vehicle system or function.

Guided Functions


VAS 5053

VAS 5051B

VAS 5051VAS 5052

(5) Identify vehicle system, interrogate fault memory

When you select a function, only the control unit that relates directly to it is control unit identified automatically and its fault memory read. Questions to help clarify possible vari-ants could be displayed as well. Press the "Vehicle system test" button to display the control unit which has been identified. A complete vehicle system test will not be carried out here but it can still be launched with the "Start system test" button in the "Vehicle sys-tem test" menu. In the case of non-automatic identification of control units, here too it is possible to make a manual selection of individual control units.

(6) Fault memory entries available?

If a fault is detected when the control unit is interrogated, this message will appear:

Malfunctions were detected, the troubleshooting for this can be performed by switching to GFF!

When you acknowledge the message, function selection will continue. However, switching to Guided Fault Finding to locate the faults is recommended.

You can see which faults occurred by pressing the "Vehicle system test" button and then "Continue". You then return to continuing your function selection by pressing "Continue" once again.

(7) Display vehicle systems, selection of further functions

Further function selection is handled the same way as function / component selection in Guided Fault Finding. You can go back to a higher level of function selection by select-ing the corresponding level on the same mask.

You can use the operating mode button to switch to the operating modes Test Instru-ments (VAS 5051 / VAS 5051B only), Vehicle Self-Diagnosis or Guided Fault Finding. Here, quitting and returning to the start mask is only possible from Guided Functions (from the original operating mode).

(8) Enter functions in test plan, function test

After a function is selected, it is entered in the test plan. The procedure from that point on is identical to that in Guided Fault Finding (see section 6.10).

(9) Perform function test

Carry out the function test. The function appears with its status in the test plan. From there, you can use the Back button to switch back to the "Select function" mask.

Guided Functions


VAS 5053

Switching operating mode

When you switch to the Guided Fault Finding operating mode, the identification that has already been carried out will be noted and utilised. The same applies when you switch between the operating modes "Guided Fault Finding" and "Guided Functions".

The protocols are continued when you change the operating mode. The same protocols apply to both operating modes.

Print functions

The following print functions are available:

• Screen (see chapter 3.5)• Diagnosis log (see chapter 3.5, section 6.13)• Function test log (chapter 3.5, section 6.14)The print functions correspond to those of Guided Fault Finding.

9.4 Install update

You can use this function to install ➚base, ➚brand and ➚flash CDs. When installing, we distinguish between:

• InstallationInstallation of a complete version.

• Install updateUpdate of a version already loaded. An update is currently only applied for a base CD. An update base CD is equivalent to a fully updated base CD, however without Win-dows operating system. The hard drive is not formatted during installation. No data is lost. However, if a different language is loaded or if there is a new compatibility number, incompatible brand data cannot be displayed.

• IncrementAn increment (addition) is possible for all software installations (base, brand and flash CDs). Increments can only be loaded by means of a network update (see section 9.5).

When installing, you must check the language and compatibility between base and brand CDs. The version of the data of the base CD appears in the start mask, for example (fig. 2-1).

The version code can be deciphered by referring to fig. 9-3. It applies to all version IDs. The following conditions apply to the use of CDs:

1. The first version block corresponds to the compatibility number, which is defined by the base CD that was loaded. All brand CDs that you want to load on the tester must have the same compatibility number. The compatibility number is not evaluated for flash CDs.

2. Version block 2 indicates the continuative version of the software (base, brand and flash CDs). This block can vary between the base CD and CDs loaded thereafter.

Note on the base software installationWith every type of installation, the following data is placed in temporary storage and therefore retained:

− the workshop code, the dealership identifier, − the settings for the online connection of your tester.

With an update / increment base CD, the following is also retained:− brand CDs, loaded flash data, installed printers and the ELSA installation.

Saved jobs (see Interruption under section 6.12.1) need to be processed prior to a base installation. If necessary, reset your print format after installation of a base CD (see section 9.13).

3. Version block 3 shows "incremental" updates, which are continuously numbered and are loaded via network updates only (section 9.5). Incremental updates only consist of changes to a complete version.

Fig. 9-3 Deciphering the version code

9.4.1 Base CD

The complete base CD (in the following simply referred to as "base CD") is bootable and in addition to the complete Windows operating system contains the run-time systems for the individual operating modes. Once the base CD has been loaded you can use all operating modes apart from Guided Fault Finding and Guided functions. The use of the latter requires a loaded brand CD (see section 9.4.3).

Loaded brand CDs, user-installed printers and diagnosis jobs saved under Guide Fault Finding (see section 6.12.1.3) are lost.

NoteThe CD update/installation of a base CD will also start automatically if you insert the CD in the CD/DVD drive and switch the tester off and on. In this way, you can also carry out a CD update/installation if the tester has become inoperable, e.g. because the calibra-tion of the touch screen has been greatly offset. In the case of the VAS 5051B a calibra-tion run is started automatically when a base CD is loaded.

9.4.1.1 Loading a base CD

You can use the "Install update" function to load the contents of a newly supplied base CD onto the tester.

1. Insert the desired CD in the CD/DVD drive. To avoid read errors, the tester should not be tilted more than 15°.

2. In Administration select the "Install update" function.3. Confirm the security query regarding the update or installation of the inserted CD.4. The contents of the CD are now copied on to the hard drive. The tester must not be

turned off during this process. After the software has been loaded, the following mes-sage appears:

Remove the bootable CD-ROM and switch the power off and on to start the new system.

5. Remove the CD from the drive and restart the system. To do so, switch the tester off and back on again. The copied data is now being installed. As soon as the start-up is complete, the start mask will appear (see fig. 2-8) following confirmation of information regarding the station name and general safety instructions.

9.4.2 Update base CD

The update base CD is solely for updating program components which form part of the base CD.

9.4.2.1 Loading an update base CD

An update base CD is loaded in the same way as the installation of a complete base CD but with these differences:

• There is no message as mentioned under section 9.4.1.1, 4 and no restart. It suffices to remove the CD once installation has finished.

• You cannot install the update base CD by switching the tester off and back on again.

9.4.3 Brand CD

You can install new or additional brand CDs on the tester.

1. Insert the desired brand CD in the CD/DVD drive. To avoid read errors, the tester should not be tilted more than 15°.

2. In Administration select the "Install update" function.3. Confirm the security query regarding the installation of the inserted brand CD.4. The contents of the brand CD are now installed on the tester. As soon as the nstalla-

tion is complete, the tester switches from Administration operating mode back to the start mask (see fig. 9-1).

5. Remove the CD from the drive.Install additional brand CDs if necessary by repeating steps 1 through 5.

9.4.4 Flash CD

A flash CD is installed in exactly the same way as a brand CD.

NoteYou can only ever load brand CDs whose compatibility number and language match the base CD; refer here to the description supplied with the CD.

When a brand CD is installed, saved diagnosis jobs of the relevant brand are lost (see section 6.12.1). For this reason you should first complete any jobs that may have been saved.

Several brand CDs for different brands can be installed on the tester (VW, Audi, and so on).

When a new brand CD is installed, it overwrites any previous installation of the same brand.

NoteIf the flash CD cannot be installed, the data for update programming of the control unit are loaded directly from the CD inserted in the drive. Please refer to the description accompanying the CD to find out what kind of flash CD it is.

9.5 Net-update

When this menu item is carried out, the tester searches via the active LAN connection for a software update under the relevant URL address "➚Mirror server" (see section 9.25.4). This can be data otherwise located on a base, brand or flash CD.

Automatic network update on startup

If a LAN connection exists, updates are searched for each time the tester is switched on and started up. If updates are found, a query appears asking whether you want to install the data. The tester should therefore be connected to the LAN network once each day when it is switched on. If the tester is not regularly connected to the LAN network, you should start the "Net-update" function manually.

You can use the "Net-update/Deactivating network update after restart" function to deac-tivate this automatic search for updates, if desired (see section 9.25.13).

Network update run sequence

If you select the "Net-update" function, the tester attempts to connect via its LAN connection to the local dealership mirror server.

If it is not possible to set up a connection, the following fault report appears:

The contacted HTTP server could not befound.Please check the connection infrastructureand the login URL (Administration)

If the tester is able to establish the connection, it will compare the version levels (of base, brand and flash data). If an update is found, a dialog box appears with a query as to whether this update should be installed. If not, a message is displayed, informing you that no new updates are available.

The data from the mirror server are initially stored temporarily on the tester and are then installed. When the base CD is updated, a message will appear telling you that the tester must be restarted.

If the network connection is interrupted during communication, the tester will attempt to restore the connection. If this does not succeed, a question will appear asking whether further attempts should be made to establish the connection, or whether communication should be cancelled.

Base system

The base system can be replaced completely up to the Windows operating system via a network update, or can be replaced in part. Complete replacement with the Windows system can only be done by installing a CD.

Network updates for the base system will not delete any brand and flash data that have been loaded. They will remain available after the update.

Brand data

An update can make changes here up to and including complete replacement of all data. A brand can only be updated on the tester if it is already there on the tester (it must have been installed at least once previously from a CD).

Flash data

During an update, the tester is informed of the flash data present on the mirror server with-out them being loaded. Any flash data required will only be loaded onto the tester when needed, via online connection.

If your tester is connected to your local LAN, the expert must have previously discussed with your system administrator the procedure for dialling into your local net-work. The necessary access authorizations have been given, the station name and IP address are known or will be provided by yourself. The expert is now able to set up a connection to your tester.

4. The expert starts its program at its expert workstation. Then a query appears asking you to accept or reject the link (see fig. 9-12). Select "Accept".

5. Now the expert sees the same mask that your tester is showing and can send control commands from there. You can see that telediagnosis is active from the remotely con-trolled movements of the pointer or from the fact that your tester does not react to op-erating functions (if the expert has set this option).

6. Via telephone, you discuss further steps to take for operating the tester and the appli-cation.

7. When telediagnosis is finished, end the connection by selecting the "Deactivate tele-diagnosis" function.

NoteDo not deactivate telediagnosis during ongoing communication, since fault reports will otherwise be received.

NoteYou yourself cannot set up a connection independently from the tester to the expert workstation.

9.20 ELSA installation

You can use this function to install the run-time system for the "Elektronische Service-Auskunftssystem" (electronic service information system) or carry out an update. Insert the ELSA installation CD and start the "ELSA installation" function.

The tester supports the operation of ELSA version 3.0 and later with the operating modes:

• Client-server mode - ELSA data written to a workshop server• Stand-alone mode - ELSA data written to the testerThe ELSA installation initially only installs ELSA's run-time system on the tester. After this you will need to load the ELSA data onto your server or tester, depending on the operating mode you want. In the latter case, insert the corresponding DVD or CD no. 1 into your tester drive and select "ELSA installation" again. If you are using ELSA data via a server, the tester must be connected via a LAN cable to your workshop network.

For further information on using ELSA and "ELSA administration", please refer to the documentation for ELSA.

After ELSA has been installed, the ELSA Win button will appear in the start mask and can be used to start this application. You can also access it from the tester operating modes via the Go to button. The "ELSA administration" function also appears in the Administration.

The program is operated via the virtual keyboard as described in section 3.3.8.5 or via a connected USB keyboard.

9.21 ELSA administration

This function calls the ELSA administration service and you will be asked to log in. In ad-ministration you can, for example, set up a new user.

Caution!Do not confuse the "ELSA Installation" function with the "ESIS Installation or Update" function! If you activate the wrong function after inserting an ELSA CD, you will no longer be able to operate the tester and it may have to be restarted.

NoteThe "ELSA Win" application is retained even after installation of a base CD.

9.23 Installation applications

You can use this function to install external applications. An appropriate installation CD must have first been installed in the tester's CD/DVD drive.

There are two types of applications, started in different ways:

• Applications that are entered under the Applications operating mode after installation, and which can be started from there (see chapter 8).

• Applications for which an extra button is added to the start mask after installation, which you can use to start them, e.g. the partner application VAS 5053 (see section 9.34). You can install up to five applications on the tester in this way.

Applications with their own start button

An application that has a start button can only be started in the start mask or the Go to Destination menu and runs independently on the tester (does not apply to the partner application). After exiting the application, the tester returns to the initial mask from which the application was started.

An operating bar may be displayed to operate the application (see section 3.3.8.5). It can also be used to go back to the tester software.

9.24 Dimension pressure / temperature

In the independent Test Instruments (see section 5.3.8 and section 5.3.9), you use this function to set the units used in your country for pressure (bar or lb/in2) and temperature measurement (°C or °F).

The following mask will appear when you select "Network settings" in the Administration mask (see fig. 9-2).

Fig. 9-17 Network settings

Setting the IP address

The tester is set so that it will automatically adopt an address from a ➚DHCP server in the workshop network. A manual input is not possible. If there is a connection, you can use "Display network settings" to have the assigned IP address displayed (see section 9.25.1).

NoteThe functions described in the following are used for connecting the tester online to the VW database server and enable the exchange of data with that server. Normally online operation takes place via the workshop network that is enabled for the database server. Independent workshops need to activate the secure client for this purpose (see section 9.25.5) and enter an appropriate login with password prior to connection setup.

The password cannot be changed directly on the tester. The following message will appear:

Please change the password centrally in ACC (dealership system user administra-tion), or ask your administrator to change it.

9.25.3 Adjustusting station name

To connect the tester to the local workshop network, it will require a unique station name. In the factory all testers are given the station name "VAS505x" (x=1, 1B, 2 or 3). It is absolutely essential to change this station name. Every time the tester is started and each time you switch to the start mask you will be reminded of this by the following mes-sage:

"VAK0200WNo network communication is possible with the current station name.

Please change the station name viathe menu item Administration / Network settings"

As long as you leave the factory-set station name unchanged you will not be able to use the following functions which need the network connection:

• Automatic network update on tester start-up• Administration / Network update• Administration / Activate telediagnosis• Administration / Network settings / GeKo test• Administration / Network settings / On-line connection• ELSA client version• Test program instruction with network access• Sending online protocols in the Guide Fault Finding application• Sending temporarily stored on-line logs at start-up

You can use this function to manage the access rights for the VW database server. The activation of the secure client can remain switched on permanently, regardless of a con-nection that actually exists.

Once the "Activate online connection via the Internet (Secure Client)" function has been successfully activated, it switches to "Deactivate online connection via the Internet (Secure Client)".

9.25.6 Proxy settings

Online access to the VW database server can be streamlined via proxy servers. You must enter the relevant proxy server address that is to be used for online connection. You can use a virtual keyboard to enter proxy addresses with up to 80 characters. If there is no entry no proxy is used for addressing.

The following address entries are available:

• HTTP proxyfor entering a normal proxy address.

• HTTPS proxyfor entering an address for secure data transmission. Data will be encrypted for trans-mission.

Select the corresponding characters for entering an address either in the form <url>:<port> or as an IP address. You can enter the URL address as IP address or as alias name. Press the "Back" button or the "Q" button to accept the proxy addresses entered.

Enter the address required e.g. the one stipulated by your IS administrator. Both address entries can exist simultaneously, apart from with the VAS 5053.

The proxy entry is retained even when a base CD is installed.

NoteThis function is only required in independent workshops, since they use the tester via the Internet, i.e. without VW workshop network.Do not switch it on if your tester is connected to the normal VW workshop network, since the online connection would no longer work in such a case.

9.31 Battery service

Battery service is offered for all testers, except the VAS 5051, and should be performed at specific intervals to maintain the battery's capacity and to adapt it to the charging cir-cuit (also see /3/). During battery service, the integrated battery is discharged to a large extent (but no total discharge!) and can then be recharged again without delay. Depend-ing on the current state of charge, this may take a few hours; the tester cannot be oper-ated during this time. That is why it is ideal to perform battery service at night or during a long stationary phase. In urgent cases, you can switch the tester off and back on again during battery service to cancel it.

VAS 5051B and VAS 5053 sequence:

The batteries of the VAS 5051B and the VAS 5053 automatically detect whether a main-tenance cycle needs to be performed. On starting up and with each change back to the start mask, the tester displays a query asking whether to start a maintenance cycle. If you confirm it with "Yes", the "Battery service" function starts automatically. If you answer with "No", you can continue to work with your tester as usual.

When you start battery service, the tester asks you to secure the power supply. This is necessary so that it can charge the battery completely first and then recharge it again after discharge. If it does not detect the power supply, it cannot start battery service. When you have confirmed the message, a security query appears again, giving you the last opportunity to cancel the maintenance cycle. If you confirm it with "Yes", the tester finally starts the maintenance cycle. No operation is possible during this time.

The tester is not switched off during the service process and can be used in the normal manner when a battery charge of approx. 30 % is reached. An appropriate message appears.

With the VAS 5053, you can only start battery service if it is really necessary, i.e. when the tester prompts you to do this. Otherwise, the function is canceled after being acti-vated.

VAS 5052 sequence:

With the VAS 5052, battery service can only be started manually. It is recommended to do this every two to three months. It is is applied too frequently, this reduces the service life of the battery, since it can only perform a limited number of charge/discharge cycles. You also start this maintenance when the battery's capacity has been reduced noticea-bly.

Administration


VAS 5053

VAS 5051B

VAS 5051VAS 5052

Disconnect the tester from the power supply when you are asked to do so by pulling the mains plug on the docking station. When you start battery service by pressing "Con-tinue", the tester starts the maintenance cycle without delay and without security query. No operation is possible during this time.

The tester discharges the battery almost completely and shuts down. Reestablish the power supply and charge the battery completely.

9.32 Display battery charging

You can use this function on the VAS 5051B and the VAS 5052 to check the current sta-tus of charge of the integrated battery. A bar display indicates the current charge.

Fig. 9-20 Battery display (example: VAS 5051B)

On the VAS 5052, the "Display battery charging" function rounds the current charge to values of 25%, 50%, 75% and 100%. It does not display any intermediate values.

The VAS 5051B gives you a graphical and a numerical percentage display (see fig. 9-20).

If the battery charge falls to 25% (VAS 5052) or below 20% (VAS 5051B), the indicator bar turns red.

You can use this function to activate and deactivate the display of ➚erWin documents. After activation, the "erWin" button appears in the start mask, which you can use to read the erWin information from a CD that is inserted. The erWin CD must always be inserted for this.

If you select this function in administration, your display switches to "Switch off erWin doc-uments". This activation hides the "erWin" button on the start mask.

9.34 Partner application (VAS 5053)

The VAS 5053 does not have a hard disk nor a DVD drive. For this reason not all Admin-istration functions can be carried out directly from the VAS 5053.

Basically these are the following functions:

• Loading new software (base CD, brand CD, flash data)• Display of the user documentation• On-line updating of software from a workshop server

These and other functions can be executed via a "partner application" from a communi-cation partner (VAS 5051B, VAS 5052 or a workshop PC).

The VAS 5053 is here connected to the partner device via the USB cable supplied. The software for the partner is included on the VAS 5053 base CD.

appears for entering the identification number of the VAS 5054 (you are given this number along with the tester). The entered PIN is stored on the tester until you acti-vate another VAS 5054 or the PIN no longer matches the VAS 5054 connected.A correct connection setup is displayed at the top, in the work window. The "Config-ure" button appears next to it. This button can be used e.g. to change the PIN.

• When you switch to the "Guided Fault Finding" and "Guided Functions" operating modes, the radio connection to the VAS 5054 is checked. A warning appears if there is no connection

The "external" connection is maintained until it is switched to "internal" or the tester is switched off.

If a connection to the VAS 5054 cannot be established correctly, disconnect it from the vehicle once and reestablish the connection.

Term Explanation

Acoustic signal A beeping or whistling tone created by the tester when, for example, the voltage of the battery reaches a limit value in buffer mode.

Adaptation This service permits interactive modification of parameters of the control system addressed and can save these new values (such as correction values for idling speed) in the control units, even perma-nently.

The user has the possibility of changing the value and transferring it to the control unit RAM for checking. The control unit now applies the new value to its outputs and the user can check the reaction of the system. If the right correction value has been found, the tester has the control unit transfer the value and the workshop code to the writeable EEPROM.

In contrast to the ➚basic setting, the control loop in question is in a closed state. With adaptation, system-specific parameters are determined and saved in the vehicle system.

Adaption values Setting values stored in the ➚control unit which can be adapted to the vehicle within a fixed range.

Administration An ➚operating mode of the VAS 505x. It is used for management of the tester.

Alphanumeric keyboard

Test plan In Guided Fault Finding and Guided Functions the ➚diagnostic objects are added to the test plan during the diagnosis session and managed. Particularly in the case of multiple suspicious diagnostic objects the test plan allows the user to keep an overview of things.Each diagnostic object is preceded by a status symbol. The diag-nostic objects are added to the test plan via read-out fault memory entries, selected observations, or the function and component selection. In addition, new diagnostic objects can be added to the test plan even from a function test or existing ones set to OK.

Test step A single, complete stage in a ➚function test.

Time record The time taken for the diagnosis session is calculated. This occurs in part by recording times which have actually elapsed, and through standard times for particular actions. In the individual phases of the ➚Guided Fault Finding, the time is calculated, added up and written into the diagnosis log in temporal units.

Time stamp Control units of the new generation will provide ➚ambient conditions as well as fault memory entries. These include the time stamp. It contains the date and time at which the corresponding fault occurred.

Touch screen A screen which has a touch-sensitive surface.

Unlearning counter

Should an error occur during a driving cycle (terminal 15 on until terminal 15 off) it is first entered as "static" in the fault memory. If it is not detected during the next driving cycle, the designation is changed to "sporadic" and an unlearning counter with an output value of, for example, 40 is decremented by 1. This is repeated during each driving cycle free of the fault, until the unlearning counter reaches 0 and the fault is thus automatically cleared. How-ever, if the registered fault should reoccur during a later driving cycle, then the unlearning cycle is set to its output value and the error provisionally set back to "static" again.

Update Software modification package for updating an existing program to a later version.1. New version of the ➚run-time system which is downloaded from

➚CD.2. New program version of a ➚vehicle system which is imported by

the tester.

Variant,variant rule

This term is used with reference to the ➚vehicle system fittings. Some fittings, for example an airbag, may be available in various variants for an identified vehicle. The most important task of the vehicle system test is to find out which variant is actually installed. If the variants cannot be determined automatically, Yes/No questions on the fitting will follow, e.g. "Automatic gearbox?". The mechanisms used to determine the variants are known as variant rules. Their results determine which diagnosis data should be made available, amongst other things.

Vehicle identifi-cation

Vehicle identification is defined by the vehicle's ➚basic feature components (type, model year, body version, engine code) that can be determined automatically or partly automatically in an existing gateway. These data are used to check a list of all possibly installed electronic control units/devices and their installation in the ➚vehicle system test.
