2.2 Mode of Operation

2.2.1 VAS 5051

You can mobilize the VAS 5051 in your workshop. Connected to a vehicle by measuring leads and sensors, it electronically supports fault finding and localiza-tion.

The core component is the tester, which remains part of the VAS 5051 in work-shop operations but can also be operated separately. You can print results on the integral printer.

1

2



2.2.2 Tester

The tester offers the operating modes "Vehicle Self-Diagnosis", "Test Instru-ments" and "Guided Fault Finding". This allows it to be used as a fault reader, as a test instrument and as an intelligent fault identification system.

The operating system and applications are stored in the tester. It can be operated with 120 to 230 V AC or from the vehicle electrical system. A built-in battery delivers up to 30 minutes of constant power when needed, so the tester does not have to be switched off when it is moved.

The tester reacts to inputs made by pressing your finger (or any other blunt object) directly on the touchscreen. An IrDA interface provides a wireless link to the prin-ter.


The workshop trolley is a mobile unit with mountings for the tester, the measur-ing leads and a printer. It has a separate mains power inlet as well as a power dis-tribution system with permanently fitted cables for connection of the tester and the printer.

With the workshop trolley the VAS 5051 can be moved around the workshop. Dis-plays and controls can be adjusted ergonomically for the user. It also provides storage space for accessories.


The measuring leads and sensors form the test interface between VAS 5051 and the vehicle. They acquire the signals coming from the test object and route them to the VAS 5051 for processing.


The two measuring leads are used for the floating multimeter. Both leads always must be adapted. The button built into the test probe of the U/R/D measuring lead controls the measurement. Depending on the selected software function, you can start or end the measurement (freeze frame) or execute special functions.




The two identical-design DSO1 and DSO2 measuring leads are used for the two- channel digital storage oscilloscope. Both measurement connections must always be adapted for each measuring lead used for measurement. The button in the red positive test probe controls measured value acquisition. Depending on the selected software function, you can start or end the measurement (freeze frame) or execute special functions.

The DSO1 lead can also be used for voltage measurements to ± 400 V (see fig. 6-2).

Current pick-up 50 A and 500 A

The current pick-up can be opened so that it can be clamped around the cable whose current is to be measured. You can adapt cables up to 12 mm (current pick-up 50 A) and 28 mm (current pick-up 500 A) in diameter. The accuracy is heavily dependent on gapless closure of the two prongs of the pick-up. To avoid measure-ment error, such as from dirt contamination of the core surfaces, the current pick-ups 50 A and 500 A each have a closure control mechanism. This signals to the software that the pick-up is closed and a measurement can be taken.

Trigger pick-up The trigger pick-up can be opened and clamped around the ignition cable used for triggering. You can adapt ignition cables up to 11 mm in diameter. The trigger pick-up picks up the start pulse as from which the signal characteristic is to be displayed on the oscilloscope. For example, clamp the trigger pick-up to ignition cable 1 when you want to display a signal as from the firing point of the first cyl-inder.

kV pick-up The kV pick-up records the ignition voltage amplitude and the ignition voltage characteristic in the ignition system. It can be opened so that it can be clamped to an ignition cable on the vehicle. There it works as a capacitive voltage divider. You can adapt ignition cables of between 5 and 9 mm in diameter.


The diagnostic cables and combo diagnostic cables are used to connect the tester to a vehicle. This gives you access to the installed vehicle systems, to the battery voltage monitor on terminal 30, to the ignition status detector on terminal 15 (if fitted), to activation of external devices with the FK-L wire, and to the power supply from the vehicle electrical system.

Diagnostic adapter The diagnostic adapter enables connection of vehicles with a 2x2-pin diagnostic connection to the diagnostic cable or the combo diagnostic cable.

Diagnostic cable LT The diagnostic cable LT allows for connection to a light truck.



2.2.5 Printer

The LED printer is used to print screen masks, test results, etc. It uses DIN A4 paper in the European version and US letter paper in the US version.

LED array The LED array exposes the points on the image drum at which toner is to be absorbed.

Image drum unit The image drum unit (see fig. 2-21) contains the light-sensitive image drum (1), a heated roller coated with an organic semiconductor and the toner cassette (2). An image of the page to be printed is transferred to the heated roller via the LED array. The exposed areas absorb the toner, which is transferred to the paper and fixed there by heat.

Fig. 2-21 Image drum unit

1 2



Display panel The printer display panel shows messages such as the ready status ("ON-LINE"), low toner, load paper, and paper out (see fig. 2-22).

Fig. 2-22 Display panel

The yellow LED ("Ready") next to the display panel indicates the status of the printer. When it lights up, the printer is ready to receive data and to prepare the data for printing. The LED flashes while the data is being received and during printing. The light goes out when the printer is not ready to receive data, such as during manual paper feed or when an error occurs.

IrDA adapter Communication with the tester is effected by way of the IrDA adapter. As long as no print job has been delivered, the LED of the IrDA adapter flashes briefly every three seconds. When a print job is being processed, the LED must "flicker" in rhythm with the data transfer.

4.1 VAS 5051

The general operation of the VAS 5051 is described in the following sections dealing with the individual components: the tester, the workshop trolley, the mea-suring leads and the printer.

Mode-specific operation is described in the relevant chapters.

4.2 Tester

Touchscreen The entire touch-sensitive surface of the screen is designated as the touchscreen. The screen senses touch by a human finger or other object, thereby replacing the conventional function of a mouse or keyboard.

Selecting To select an element (text or button), you must touch it on the screen. It changes color to indicate that it has been selected. Text turns white and is high-lighted by a black selection bar; buttons turn dark gray (see page 4-3). As long as you are touching the screen, you can change the current selection. When you stop touching the screen the selected element is activated.

.

The screen reacts to all touching. When using the tester, make sure it cannot be touched unintentionally by equipment or people.

When you touch the slide bar to the left or right of the control, the value increases or decreases by 1.

4.2.2 Using the Virtual Keyboard

The VAS 5051 tester does not have a conventional keyboard. If text entries are necessary, a so-called "virtual keyboard" appears on the touchscreen, which you can operate via the individual buttons.

The virtual keyboard consists of an input box offering various buttons and a dis-play box above the input box in which the text you enter is displayed.

The tester has two kinds of keyboard: an alphanumeric keyboard (fig. 4-4 and fig. 4-5) and a numeric keyboard (fig. 4-6).

.

The tester cannot be operated with an externally connected keyboard. The PS/2 keyboard port (see fig. 2-4) is used only for servicing by the vendors.


Operation

Alphanumeric keyboard

When the alphanumeric keyboard appears on the screen you can enter numbers, special characters and letters. You can read the entry in the gray box above the keyboard.

To enter text or a number sequence, press the desired keys one after the other.

Fig. 4-4 Alphanumeric keyboard (lowercase)

Fig. 4-5 Alphanumeric keyboard (uppercase)

.

A sound will signal if the text or number sequence is too long.

Operation


Special keys The alphanumeric keyboard has special keys that are recognizable by their lighter background. They have the following functions.

You can use this button to clear and correct your input. If you choose "C" for "Clear", the last entered character is deleted. If you use this button repeatedly, the characters are cleared backwards as long as there are still characters left to clear.

The "Q" button signifies Quit. Use this button to confirm and terminate your input.

The "SH" (Shift) button corresponds to the Shift key on your keyboard. When you press the button, the virtual keyboard display switches from uppercase letters with special characters to lowercase letters with numbers or vice versa (see fig. 4-4, fig. 4-5). This button appears only in the alphanumeric keyboard.

The button with the label "CR" (Carriage Return) corresponds to the return key on a normal keyboard. It appears only when you choose "SH" on the alphanu-meric keyboard. By choosing "CR" you can enter more text on a second line. The information window at the left shows the possible number of lines.

This button is needed to insert a blank space between words or letters.


Operation

Numeric keyboard Enter the desired value by touching the numbers. The entered numbers are dis-played in the gray field above.

Fig. 4-6 Numeric keyboard

Special keys The numeric keyboard contains the special keys "C" and "Q". Their functions correspond to those on the alphanumeric keyboard.

Operation


4.3 Workshop Trolley

Mobility The workshop trolley allows for mobile use of the tester in the workshop. It has four wheels so that it can be easily moved around the work environment.

To fix the workshop trolley in place, the two front wheels have brakes. Use the brakes in order to avoid movement of the workshop trolley during use.

If you want to move the workshop trolley, release the brakes. You can push or pull the trolley with its all-round handle bar (ram protection bar), then reset the brakes.

If you need to move location, you can disconnect the power cord from the tester while it is still on (the tester temporarily switches to battery backup) and recon-nect the mains power at the new work location.

To remove the tester from the workshop trolley:

1. Disconnect the power to the workshop trolley (also while still switched on).

2. Unplug the power connection and remove all measuring leads.

3. With one hand raise the retainer, and with the other lift the tester out of its position.

Re-install the tester in reverse order.

Storage You can place the measuring leads and sensors on both sides of the workshop trolley on the holders provided. You can roll up longer cables, such as the 5 m diagnostic cables, on the cable reels on the sides.

During operation you can fold the dust protection cover for the VAS 5051 and store it in the drawer. The drawer also provides room for the operating manual and up to 3 CDs.

.

When the VAS 5051 is not in use, the dust protection cover should be always be placed over the workshop trolley.


Operation

Tester mounting When shipped, the tester is in its installation position and is held in place by a spring catch on its top.

You can change the tilt angle of the tester on its mounting by holding onto it at the top and bottom and swiveling it in the vertical. In this way you can work ergonomically with the VAS 5051 in varying positions.

Using the tester wit-hout the work-shop trolley

The tester is designed to be used on the workshop trolley with which it is shipped. If the tester needs be used on test drives, the following points should be noted:

Direct power con-nection of the tester

Place the separate power cable in the power socket of the tester (see fig. 2-4) and connect it to your workshop power source.

+

Attach the tester securely on the vehicle’s back seat with a strap and connect it to the vehicle by the 3 meter diagnostic cable or the 3 meter combo diagnostic cable. A second person must sit on the back seat to operate the tester.

.

The tester can be powered from the vehicle’s electrical system only via the 3 meter diagnostic cable and the 3 meter combo diagnostic cable.

Vehicle Self-Diagnosis


5 Vehicle Self-Diagnosis

5.1 Overview

In the "Vehicle Self-Diagnosis" operating mode you can communicate with the vehicle systems on the diagnostic bus when the connected diagnostic cable is connected and the ignition on. You can select the desired vehicle system from dialog masks. From the masks you can start the possible diagnostic functions for the vehicle system concerned and, for example, retrieve test results or execute a final control diagnosis, etc.

To work with vehicle self-diagnosis you need the relevant Workshop Manual.

If you select a vehicle system that is not fitted in the connected vehicle you receive the following message:

Vehicle system not available.

You also receive a message if you select a diagnostic function that is unknown to the vehicle system or if the function cannot currently be executed:

Function not recognized or not currently executable.

Switch You can switch to the following operating modes in the vehicle self-diagnosis masks using the buttons on the navigation bar:

• Test Instruments and

• Guided fault finding (only if you previously switched from guided fault fin-ding to vehicle self-diagnosis).

Go to An operating mode can be cancelled or terminated with the Go to function.

Print When you select the "Print" button, you can choose various printout options from a pull-up menu:

• Screen: A screen print that outputs what you see on-screen to the printer.

• Save result: The tester saves the current result in the self-diagnosis log. If the log already contains data, the first time you execute "Save result" after prin-ting out the self-diagnosis log a query appears asking whether you want to de-lete the saved data. Press the "Erase" button to overwrite the old data; press "Do not erase" to append the new data to the old. The self-diagnosis log is retained when the tester is switched off, unless it is explicitly erased.

• Self-diagnosis log: This selection is only displayed if results have been saved beforehand. The tester outputs the saved results to a connected printer.



5.2 Start Vehicle Self-Diagnosis

The "Vehicle Self-Diagnosis" operating mode is activated from the start mask by choosing the "Vehicle Self-Diagnosis" button (see fig. 5-1).

Fig. 5-1 Start mask, activating "Vehicle Self-Diagnosis"

When you choose this button in the start mask, the tester offers a list of all known vehicle systems (see fig. 5-2), whether or not they are fitted in the vehicle being diagnosed.

Vehicle-self-diagnosis is designed for KW1281, KW2000, OBDII and LT vehi-cles. KW1281 and KW2000 use largely identical masks. The VAS 5051 automat-ically detects whether a control unit is working to KW1281 or KW2000.

The number of faults found in the memory is shown in the left-side information window. All saved items of fault information are displayed in the work window. The information consists of a five-part fault ID number and the associated text. If the fault occurs sporadically, this will be indicated on an extra line.

If the memory contains more faults than the screen can display, the tester offers a scroll bar at the far right side with which you can move the list up or down.

For KW2000 you can click on the "Continue" button to view the ambient conditi-ons under which the fault occurred.

5.4.2 "Final Control Diagnosis" Diagnostic Function

When you select the "03 - Final control diagnosis" function in the "Select diag-nostic function" mask (see fig. 5-4), the tester activates the initial final control element. In the lower left-side information window, the note "1st final control being tested" appears.

In some cases, the process can be observed visually (e.g. indicator lamps) or acoustically (e.g. relays).

Switching from vehicle self-diagnosis into the test instruments allows you to monitor the activated final control element and its results with the multimeter or oscilloscope, for example.

Fig. 5-6 "Final control diagnosis" mask

You can call up and display the next final control element by choosing the "Con-tinue" button. Final control diagnosis is canceled with the "Back" button.

5.4.3 "Erase Fault Memory" Diagnostic Function

The "05 - Erase fault memory" job deletes the fault memories of the selected vehicle system. When you call up the function, the tester shows a dialog box with the following prompt:

Execute function?Note: Data will be deleted.

Press the "Cancel" button if you mistakenly activated the function or the "OK" button to irretrievably delete the data.

The job is confirmed in the left-side information window:

Fault memory erased

The "Erase fault memory" function automatically follows the "Interrogate fault memory" function. This means that if the fault has not been rectified in the vehi-cle, causing the fault code still to be detected and stored in the vehicle system, the contents of the fault memory are again displayed by the tester. The left-side infor-mation window then shows:

Fault memory erased1 fault(s) detected

The fault information is additionally displayed in the workspace.

5.4.4 End Output

When you want to exit vehicle self-diagnosis for the selected vehicle system, select the "06 - End output" function in the "Select diagnostic function" mask (see fig. 5-4) or choose the "Back" button.

The program returns to the "Select vehicle system" mask. There you can terminate "Vehicle Self-Diagnosis" mode by selecting "Exit" from the menu and you will re-turn to the start mask.

.

You can erase the fault memory only if you previously read it via the "Interro-gate fault memory" function (see section 5.4.1). This prevents important infor-mation on faults being lost.



5.4.5 "Read Data Block" Diagnostic Function

When you select "08 - Read data block" in the "Select diagnostic function" mask (see fig. 5-4), you can read and cyclically display a data block from the vehicle system. Enter the desired display group ("Display group No." in the Workshop Manual) to get the relevant measured values.

Erase learnt values By selecting the channel number "0", you can erase all learned values saved in the vehicle system. The tester responds in the left-side information field with the query:

Channel 0Erase learnt values?

Choose the "Continue" button to erase the saved values or the "Back" button to cancel the function and return to the "Select diagnostic function" (fig. 5-4) mask. When the values have been deleted the tester confirms the fact in the left-side in-formation window.

5.4.7 "Update Programming" Function

With the "Update programming" diagnostic function (fig. 5-4) you can update the vehicle system’s program status with the VAS 5051.

Select diagnostic function

This diagnostic function option appears only if update programming can be per-formed with this vehicle system and there is a more up-to-date version of the pro-gram in the tester. When you have successfully completed update programming for a vehicle system, the diagnostic function for it is no longer offered.

You can start the diagnostic function by choosing "Update programming". If the necessary conditions are not met in the vehicle system, a warning appears. Estab-lish the necessary conditions indicated and restart update programming.

The process is dialog-guided, across several different masks:

• An information text showing the new version number appears. Follow the prompt it gives.

• The new update program is loaded into the vehicle system. This operation takes several minutes. Its progress is shown continuously by a progress bar; on completion the programming log information appears on-screen.

• Switch the ignition off and back on again.

• The fault memories of all vehicle systems are erased.

If a fault occurs in the process, the vehicle system is no longer ready for service. The fault is displayed, and the diagnostic functions selection (fig. 5-4) shows only the "Update programming" function. Repeat update pro-gramming.



Self-diagnosis log During the operation you can record the results in the self-diagnosis log. Of spe-cial interest is the programming log information showing the vehicle version before and after update programming and the programming status.

Help Once you have selected the diagnostic function you can get more assistance by choosing the "Help" function.

On the screen the buttons which can be used to select the measurement functions in the two function blocks are shown in differing font colors.

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 exam-ple see fig. 6-9).

Each of the measurements is run as if it were the only measurement being per-formed.

In order to display both sets of measured values, the display box is split in two. The first measured value is displayed on the left, the second on the right parallel to it. Both are displayed cyclically.

Bar display The measured value bar and the min/max display are not shown as long as two measurements are being performed at the same time.

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" mode if has been more than an hour since the last switch.

You can also perform the calibration manually if necessary (see "Calibrate" but-ton, section 6.3.8).

You should always perform a manual calibration after switching the DSO mea-suring leads or moving the current pick-ups to a different position, or if you have not used the VAS 5051 for a lengthy period of time, especially if it has been exposed to extreme temperature variations.

Perform the calibration manually to compensate for additional contact resistances through to the measured object in resistance tests. Short the connections to the measured object and perform the calibration manually. The calibration will then cover not only the measuring lead but also the connections to the measured object.

The "Measuring mode" button is used to set parameters for recording measured values.

After you press this button, the buttons "Auto Setup", "Auto Level", "Auto", "Normal", "Single" and "Draw mode" are displayed under the display box.

Fig. 6-13 "DSO" mask, Auto Level mode, Measuring mode

In auto setup mode the amplitudes of channel A and B, the time base and the trig-ger 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).

In normal mode, cyclical data collection takes place only when a valid trigger event occurs. If the trigger is missing, a prompt appears in the display box at the right.

6.4.5 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 opti-mally 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 fol-lows: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" modes: The triggering is only optimum if you adjust the trigger point to an unambiguous 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 be displayed.

Now return the trigger manually to the amplitude range until the message disap-pears.


Test Instruments

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.

When you move out of auto setup mode triggering is set automatically to 0 % of the amplitude value. In trigger mode you can use the slide control 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. You will then get a signal curve even if the trigger is outside the amplitude.

Now adjust the trigger manually to an unambiguous value in the amplitude range.

Normal Use normal mode if you are familiar with operation of the DSO. You will only get a triggered image when the trigger is within the amplitude range of the mea-sured signal.

Single In single mode you can record a one-off event. The signal is measured and dis-played immediately as a freeze frame. Note that a valid trigger event must have occurred.

Guided Fault Finding


7 Guided Fault Finding

7.1 Overview

The "Guided Fault Finding" operating mode "guides" you from detecting a vehi-cle malfunction (fault symptoms) to finding the fault origin and solution. All vehicle information (equipment, symptoms, functions and components, docu-ments, and test programs) is compiled automatically.

All functions in the "Vehicle Self-Diagnosis" and "Test Instruments" operating modes are available for "Guided Fault Finding".

The fault symptoms are delivered to guided fault finding from two different sources:

• Fault memory contents

• Complaint reports

In addition, you have the option of selecting and executing function tests of sus-pect functions or components.

The guided fault finding process is shown in fig. 7-1.

Vehicleidentification

Guided fault finding begins with vehicle identification. You can choose the vehi-cles and basic characteristics from selection menus un a sequence of five masks. At this point, the tester does not need to be connected to the vehicle.

Vehicle system test After the vehicle identification, the vehicle system test is performed with the diagnostic cable connected and the ignition on. All electronic vehicle systems that could occur in the identified vehicle are displayed in a list. The vehicle com-munication checks which vehicle systems are available, and their fault memories are read.

.

On devices with marque separation you can only use "Guided fault finding" mode if at least one marque-specific CD is installed on the VAS 5051. For details of installation of marque-specific CDs refer to section 9.4.



Complaints If no fault is detected in the vehicle system test, the guided fault finding automat-ically branches to input of complaints. You can enter the customer’s complaints as well as your own observations. Several symptoms can be formulated to arrive at precise fault characteristics. The tester analyzes the symptoms with the expert knowledge held on the hard drive.

Function andcomponent selection

Here you can enter functions or components that, based on your experience, could be possible sources of the fault. The selected functions and/or components are entered in the test plan (Own test plan).

Test plan From the test plan, the function test or tests is/are processed one after the other. The results lead to a re-evaluation of the test plan so the sequence of suggested function tests may change, function tests may be removed or others may be added.

Function test A function test is a sequence of test steps that check a vehicle’s functioning, a component group or a component based on fixed requirements. The test program delivers an indication of the status of the tested vehicle functions, component groups or components, e.g.: "OK", "Not OK", "Don't know", etc. The function test is dialog-guided, uses the test instruments options (multimeter, oscilloscope), and communicates with the vehicle systems.

Exit guidedfault finding

When you exit from the guided fault finding, the fault memories of the electronic vehicle systems are erased automatically and then read out. If faults still occur, the guided fault finding can be continued or canceled based on the user's deci-sion.

Switch In guided fault finding, you can switch to the "Test Instruments" or "Vehicle Self-Diagnosis" operating modes via buttons on the navigation bar. Then you can exe-cute a measurement or diagnostic function, for example. "Test Instruments" and "Vehicle Self-Diagnosis" functions currently in use by guided fault finding are hidden.

Switching back to "Guided Fault Finding" mode always exits the mask in which the "Switch" button was clikked. There processing of the mode can be resumed without limitations.

7.2 Start Guided Fault Finding

"Guided Fault Finding" is called up from the start mask by choosing the button with the same name. The start is followed immediately by the vehicle identifica-tion function.

.

You can save time by starting guided fault finding immediately with a connected diagnostic cable and the vehicle’s ignition on. Then, after the vehicle identifica-tion the VAS 5051 automatically interrogates the fault memory contents of the definitely installed vehicle systems.

The destination menu contains the titles of the fault finding masks that have been accessed, e.g. "Vehicle system test", "Fault memory contents", "Test plan" and sub-masks of the function test. User-guided masks such as "Complaint report", "Function/Component Selection" as well as "Documents" also are contained in the menu (for example see fig. 7-30).

Since the "Test Instruments" and "Vehicle self-diagnosis" operating modes can be activated directly with buttons on the navigation bar, they are not included in the "Go to" destination menu.



7.4 Vehicle Identification

The vehicle identification function serves to provide a unique identification of the vehicle and its equipment, and subsequently delivers the associated test data.

In vehicle identification, you select the basic characteristics of the vehicle from a series of selection lists. Basic characteristics are:

• marque,

• type,

• model year,

• body version and

• engine code letters

The selected characteristics are shown in the right-side information window so you can check the selection.

You can switch to the previous mask at any time with the "Back" button in order to make a different selection.

7.6 Vehicle System Test

The vehicle system test is used to check the electronic systems installed in the vehicle. Communication with the control unit of the corresponding vehicle sys-tem is checked, and the fault memory read out, individually in succession.

All possible vehicle systems and their variants for the identified vehicle are shown in the "Vehicle system test" mask (see fig. 7-6). They are compiled in a list in the following groups:

• Drive unit and power transmission

• Running gear

• Body / Heating, cooling, air conditioning / Electrical system

For the sake of clarity, the lines for each group are distinguished by different background colors.

The vehicle system test is performed

• when the diagnostic cable is already connected, by choosing the "Continue" button in the "Confirm vehicle identification" mask (see fig. 7-4) or

• by connecting the diagnostic cable subsequently and then choosing the "Con-tinue" button in the "Connect vehicle to VAS 5051" mask (see fig. 7-5).

Observe vehicle system test

In the vehicle system test the possibly installed control units are addressed via the diagnostic lead connected to the vehicle, and their fault memories are read. If the communication link is successfully set up, in the "Vehicle system test" mask the relevant list entry, e.g. " Motronic engine management system", is highlighted (control unit successfully identified with or without fault).

If a control unit included in the selection list has not been identified, it should be manually selected from the mask by the user. Only then will the associated diag-nostic data be delivered in the function/component selection .

The rest of the vehicle system test can be observed on the touchscreen. The desig-nation of the tested vehicle system is shown in the left-side information box, e.g.:

Motronic engine management system

During the "Read fault memory" process the associated line is flagged by an arrow symbol: "<==".

Identified vehicle systems are highlighted with a black bar; the text is inverted. Vehicle systems that are ruled out by an already identified system are skipped.

For vehicle systems that cannot be unambiguously identified, a prompt appears when necessary to clarify the actually installed equipment.

Systems whose fault memories are not empty show the status "Fault" in the line at the right.



After an executed test, the information box in the mask shows the message:

Control units interrogated

The vehicle system test requires a functioning diagnostic connection to the vehi-cle, otherwise the following message appears during communication with the first control unit:

Diagnostic bus faulty

No voltage or voltage too lowon diagnostic bus

Vehicle battery voltage too low?Diagnostic connector connectedto vehicle?

Fault number: 200.17

First check whether the ignition is on and confirm the message with "Repeat". If the message appears again, your further decisions should take account of whether the vehicle system is definitely installed or not. All entries for vehicle systems highlighted with a black bar in the "Vehicle system test" mask are definitely installed.

Definitely installed control unitnot detected

If communication with a definitely installed control unit is not possible, no mark is made in the list and the following prompt appears:

Communication withdefinitely installed control unitnot possible.

Retry Cancel

If no communication is possible after "Retry", select "Cancel".

The following prompt appears:

Control unit not recognized.

To enter it anyway,choose "OK".

Choose "OK" so that the data relating to the definitely installed control unit (diagnostic objects) are available.

.

If all control units have been interrogated, you must select the "definitely instal-led control units" in the "Vehicle system test" mask manually.



Optional vehicle system not recognized

If an optionally installed vehicle system could not be identified, its entry in the list is not marked. The same prompt as for "definitely installed" control units appears.

Click "OK" if you are sure that the vehicle system is installed.

Observe vehicle system test

Fig. 7-6 "Vehicle system test" mask, test finished

During the vehicle system test, all the buttons on the navigation bar except "Help" are hidden.

After the vehicle system test is finished, you can navigate with the "Continue" or "Go to" buttons.

Pressing the "Continue" button always leads you to the "Fault memory contents" mask (see fig. 7-7).

You can use the "Go to" button in this mask to enter the "Function/component selection" mask (see section 7.11).

7.9 Function Test

A function test is assigned to each vehicle function, component group and com-ponent. Its task is to test the set requirements. The result is either "OK", "Not OK" or "Test result unknown".

A function test mask is shown in fig. 7-9. Each function test consists of self-con-tained steps that can be repeated after processing via the Go to menu. The desig-nation of the current test step being run through is shown in the mask in the left-side information window.

A function test can use the full measurement functionality of the tester over the diagnostic bus, as well as the multimeter and the oscilloscope. Also, you are actively involved in the process for connecting measuring leads, making deci-sions and entering values, for example. The corresponding image documents are also offered for display in the function test.

After completing the function test, you switch back to the "Test plan" mask. There you can access alternative diagnostic procedures via the "Go to" menu (complaints, function/component selection).

When a function test is started, in this example a general note on the test first appears:

7.9.1 Test Dialogs

The following types of user/test dialogs occur within the function test:

• Yes/no questions with two buttons to answer

• Measurement instruction with one button to start or stop cyclical measured value display

• Prompts to the user with one button for messages

• Menus with selection options up to eight buttons

• Result displays with one button to start or stop cyclical measured value dis-play

• Displays without button for cyclical output of texts or values. A cyclical out-put can be interrupted either by program control from the test program or by pressing a button.

Input instructions to enter a number value or text by way of an on-screen key-board.

Each test dialog step is activated only by pressing a corresponding button, e.g. "Ready/Finished", "Yes", "No", etc.

Every test dialog step can contain buttons for displayable image documents. The images are displayed by choosing the appropriate button, switching into the doc-ument display and then returning to the test dialog step.

Yes/No question The "Yes/No question" mask is used to check test prerequisites. The mask may contain additional buttons to activate help texts or documents.

The "Yes/No question" is confirmed with the "Yes" or "No" button. Then the "Continue" button is active.

Dialog boxes with Yes/No questions, menus or prompts are continued automati-cally with the "Yes" button.



Measurement instruction

The workspace of the "Function test, Voltage measurement" mask (see fig. 7-12) contains a description of the measurement ("Test voltage to driver’s side central locking"), an indication of the measurement type ("Voltage measure-ment"), the instructions for connection of the measuring lead, and the specified target and measured values, with analog and numeric output.

The analog measured value display contains a numerically labeled scale. A rect-angle indicates the tolerance range for the measured value. The measured value appears as a horizontal, colored bar in the labeled scale. If the measured value is OK (green), the bar protrudes into the tolerance window.

The numeric display also contains the physical measured unit.

Measurements of numeric values must be triggered separately after setting up the specified connections and choosing the "Measure" button. The measurement is repeated cyclically several times, for as long as the button is pressed; the last measured value after pressing the "Continue" button is accepted. When you press the "Measure" button again, the continuous measurement is stopped and the last displayed value is maintained. For measurements that are triggered by a certain trigger condition (events), the "Measure" button releases the trigger. The mea-surement is triggered automatically when the trigger event occurs.

Alternatively, the "Measure" button can be remotely triggered via the button in the red test probe.

Default values,using own measu-ring equipment

If the internal measurement device is defective, or if you prefer your own mea-surement device, you can enter the determined test value via an on-screen key-board. The keyboard automatically appears when you touch the input box or if the internal test instruments are faulty. Remove the keyboard from view after ending input by choosing "Q" or "Continue" or by triggering a genuine measure-ment with the "Measure" button. The physical unit for the input (e.g.: V, mV) is set automatically.



Default value input in communication with vehicle systems

If communication with vehicle systems is not possible, a "Fault signal" dialog box appears. When you confirm the dialog box with the "Cancel" button, a fur-ther dialog box appears with the query:

Continue with default values?

If you answer the question with "yes", a keyboard for entry of data is displayed.

Using theon-screenkeyboard

A numeric keyboard is displayed in the test dialog window for input of default va-lues. Enter the values by pressing the buttons. The values you enter appear in the one-line display box of the test dialog window. You can erase entries backward character by character with the "C" button and then retype them. You can enter a maximum of 64 characters. Terminate input with the "Q" button or the "Continue" button. The keyboard is then hidden from view. You can display the keyboard again by clicking on the display box.

7.9.2 Working with the Digital Storage Oscilloscope (DSO)

Graphicalcurves

Graphical curves are measured and displayed cyclically by the DSO with the pa-rameters set by the function test. Choose the "Freeze frame" button to stop cyclical repetition of the measurement. The last display remains static. Choose the "Freeze frame" button again to restart cyclical repetition of the measurement. The "Freeze frame" button can also be activated with the button in the red test probe.

7.9.3 Exit Test Step

You can exit the "Function test" mask to switch to the "Test plan" only when all user inputs have properly terminated and an unambiguous test status has been re-ached. Missing information or user actions still needed are indicated by prompts.

.

Input of default values for measurement values from vehicle systems requires special knowledge about the system.



7.9.4 Returning to the "Function Test" Mask

You can switch to a previous mask by choosing the "Back" button or via the "Go to" menu

7.9.5 Exit Guided Fault Finding

You always quit guided fault finding by choosing "Exit" from the "Go to" menu. This action erases the fault memories of the vehicle systems are erased and reads them out again to display any still existing faults. If a fault memory is still set, the following message appears:

All fault memories have been erased,but relevant faults have remained recordedor have been recorded again.

To restart from the "Fault memory contents"mask, press "OK".

To cancel and exit, press "Cancel".



7.10 Complaint Report

The "Select complaint" mask is displayed automatically if no vehicle systems faults were detected in the "Fault memory contents" mask (see fig. 7-7) and you chose the "Continue" button there. The input of complaints is an extra option for input of fault symptoms.

The "Complaint report" masks contain lists of terms with which you can enter the complaints reported by the customer or those that you detect. A complaint can relate to a repair group or to perceptions, and is described by one or more fault symptoms.

You can select one element per mask from the lists of terms. Each selection is accepted immediately and an automatic switch is made to the next mask. You can go to the previous mask at any time with the "Back" button and change your selection. The selected complaints are displayed one after the other in the right-side information window of the masks.

You do not have to indicate all levels of a certain complaint. As soon as the "Con-tinue" button appears, you can switch to the "Display all selections" mask (see fig. 7-18).

7.11 Function/Component Selection

You can use your personal expert knowledge with the help of the "Function/com-ponent selection" function in the course of guided fault finding. In contrast to the evaluation of fault memories (see section 7.7) or complaint reports (see section 7.10), here you can directly select suspect functions or components.

After selection of the functions or components, the tester automatically assigns the appropriate function tests. In this way, you set up your "own test plan". The designations of the functions or components appear in the "Test plan" mask under "Own test plan" if system-guided test proposals are already present. In the remainder of the example this is assumed to be the case.

You enter the "Function/component selection" mask from the "Vehicle system test" mask with the "Go to" button. Selection of function, repair group, compo-nent group and component from the displayed lists is spread over several masks, similarly to the complaint report (see section 7.10).

When selecting functions and components, the list display builds in the form of levels identified by indents to the right of the previous selection. Example:

Drive unit ADR Engine 01 - Systems capable of self-diagnosis

Electrical componentsetc.

Each indent indicates a selection in a mask. To jump back one level, select the previous level. Example:

Drive unit ADR Engine

9.1 Overview

The "Administration" operating mode provides no functions for fault finding on vehicles. Rather, it is used for internal management of the tester. In this operating mode, you can adapt the settings to your requirements.

The following functions are available:

• Installation of updates

• Self-test of test instruments and diagnostic bus

• Input of the workshop code or change of dealership identifier

• Setting and selection of the signal tone, date and time, output language and initial graphic

• Information on an inserted CD

Input of workshop code

During initial startup, "Administration" is the only operating mode that can be activated after the tester starts. You must enter your workshop code to access the other VAS 5051 operating modes (see chapter 3 and section 9.6). After entering the workshop code once, only the dealership identifier can be changed with this function.

.

Later changes or deletions of an entered workshop code can be made only by specially authorized personnel who have access to the "Expanded functions" function (see section 9.9). Therefore, make sure to enter the correct code.

Troubleshooting



A function test of the U/R/D measuring lead and the COM measuring lead is per-formed as follows. If the test results do not conform to the required values, there is a fault in the lead concerned. In this case, send a fault report as shown in section 11.4.

1. Connect the measuring leads to the tester.

2. Activate the "Resistance U/R/D" button in the "Multimeter" mask in "Test Instruments" mode. Select automatic measurement range selection (see section 6.3).

3. If the test probes of the two measuring leads are not contacting, the following result should be displayed:

+++++ MΩ.

4. Now short the connection between the two test probes. The displayed result must be ≤ 10 Ω. If it is not, at least one of the measuring leads is probably defective.

Measure the line resistance to determine which of the measuring leads is defec-tive:

1. Disconnect the COM measuring lead from the "COM" socket.

2. On the screen, manually select the measurement range "0 .. 10 Ohm" (see section 6.3). The following prompt appears in a dialog box:

To calibrate connect U/R/D and COM test probes together.

3. Plug the test probe of the U/R/D measuring lead into the "COM" socket and press the OK button. The displayed measured value must be ≤ 0.03 Ω.

4. Check the freeze frame selection by pressing the button on the test probe. The measured value is frozen, the on-screen "Freeze frame" button must appear pressed.

5. Remove the U/R/D measuring lead and reconnect the COM measuring lead again. Plug the safety test probe into the "U/R/D" socket. The displayed mea-sured value must be ≤0.03 Ω.


Troubleshooting

DSO measuring leads

A function test of the DSO measuring leads is performed as follows. If the test results do not conform to the required values, there is a fault in the DSO measur-ing lead concerned. In this case, send a fault report as shown in section 11.4.

1. Connect a DSO measuring lead to the DSO1 socket.

2. Touch the "Voltage DSO1" button in the "Multimeter" mask in "Test Instru-ments" mode. Select the "Direct voltage" measurement type and automatic measurement range selection (see section 6.3).

3. Connect the test probes of the DSO measuring lead to a charged auto battery. The displayed measured value must correspond to the battery voltage (bet-ween 11 and 14 V).

4. Check the freeze frame selection by pressing the button on the test probe. The measured value is frozen, the on-screen "Freeze frame" button must appear pressed.

Now perform a comparative test between U/R/D and DSO:

1. Unfreeze the freeze frame by touching the button again to resume the measu-rements.

2. Also connect the U/R/D measuring lead and the COM measuring lead to the tester and the auto battery. You should first check the proper function capa-bility of both measuring leads.

3. Touch the "Voltage U/R/D" button. Select the "Direct voltage" measurement type and automatic measurement range selection (see section 6.3).

4. The difference between the measured values should be ≤ 0.2 V in both the displayed measurement functions (DSO1 and U/R/D).

Repeat the function test with the second DSO measuring lead.

.

Both the DSO measuring leads are identical and can be interchanged for testing.

Troubleshooting


Current pick-up 50 A A function test of the current pick-up 50 A is performed as follows: If the test results do not conform to the required values, there is a fault in the current pick-up. In this case, send a fault report as shown in section 11.4.

1. Connect the current pick-up 50 A to the tester.

2. Touch the "Current 50A current pick-up" button in the "Multimeter" mask in "Test Instruments" mode. Select the "Direct current" measurement type and automatic measurement range selection (see section 6.3).

3. Open and close the current pick-up several times without connecting it to a live electrical cable. The measured value must change significantly between the two conditions. When the pick-up is open, this message appears in the display window at the top right:

Current pick-up not closed.

Check the calibration of the current pick-up:

1. Press the "Calibrate" button on the screen. Ignore the message in the dialog box which appears, and press the "OK" button to close it. The measured value displayed must now be ≤ 0.05 A.

2. Connect the current pick-up to a battery cable or another cable of a power consumer in a vehicle. All consumers and the vehicle ignition should be off initially. The displayed measurement result must be ≤ 1 A.

Perform a comparative test:

1. Switch on a < 50 A consumer, such as the parking lights. The current con-sumption should be as exactly known as possible. Use this as an empirical va-lue. The measured value must match the empirical value.

2. Disconnect the current pick-up from the live cable, rotate it through 180 degrees and reconnect it. The difference in measured values must be ≤ 0.5 A, but the preceding sign must be inverted.


Troubleshooting

Current pick-up 500 A

A function test of the current pick-up 500 A is performed as follows: If the test results do not conform to the required values, there is a fault in the current pick-up. In this case, send a fault report as shown in section 11.4.

1. Connect the current pick-up 500 A to the tester.

2. Touch the "Current 500A current pick-up" button in the "Multimeter" mask in "Test Instruments" mode. Select the "Direct current" measurement type and automatic measurement range selection (see section 6.3).

3. Open and close the current pick-up several times without connecting it to a live electrical cable. The measured value must change as the condition chan-ges.

Check the calibration of the current pick-up:

1. Press the "Calibrate" button on the screen. Ignore the message in the dialog box which appears, and press the "OK" button to close it. The measured value displayed must now be ≤ 0.5 A.

2. Connect the current pick-up to a battery cable or another cable of a power consumer in a vehicle. All consumers and the vehicle ignition should be off initially. The displayed measurement result must be ≤ 5 A.

Perform a comparative test:

1. Switch on a heavy power consumer, such as the lights and the heated rear window. The current consumption should be as exactly known as possible. Use this as an empirical value. The measured value must match the empirical value.

2. Disconnect the current pick-up from the live cable, rotate it through 180 de-grees and reconnect it. The difference in measured values must be ≤ 5 A, but the preceding sign must be inverted.

Troubleshooting


Trigger pick-up and kV pick-up

The only way to check these two pick-ups is together. The function test is per-formed as follows: If the test results do not conform to the required values, there is a fault in one of the pick-ups. In this case, send a fault report as shown in section 11.4.

1. Connect the trigger pick-up and the kV pick-up to the tester.

2. Call up the "DSO" mask in "Test Instruments" mode (see section 6.4).

3. Connect both pick-ups to a vehicle with a 4- or 6-cylinder engine by the same ignition cable (secondary side of the ignition coil).

4. Press the "Default measurement" button in the "DSO" mask. Select the "Ca-ble test kV TZ" curve in the selection box that appears, then press the "Dis-play" button to confirm. The "DSO" mask appears with the target curve in the background. At the same time all of the DSO settings are performed automa-tically.

5. Start the vehicle’s engine. The typical ignition signal similar to the target cur-ve must be dynamically displayed – that is, the mask is refreshed once or twice per second if the kV pick-up and the trigger pick-up are fault-free.

If the trigger pick-up is defective, this message appears in the box at the top right:

No trigger.

If the kV pick-up is defective, you may see only a horizontal line or a measure-ment curve with a much too low amplitude.

.

Depending on the vehicle, the amplitude of the ignition signal can fluctuate between 4 and 40 kV. The sparking voltage is typically between 600 and 1200 V, the combustion period may be between 2 and 6 ms. The shape of the curve may vary depending on ignition coil manufacturer.


Troubleshooting

3 meter, 5 meter dia-gnostic cable

The function test of a diagnostic cable is performed as follows:

If the test results do not conform to the required values, there is a fault in the diagnostic cable. If this is the case, you should send a fault report as shown in section 11.4.

1. Connect the tester to a vehicle by the diagnostic cable.

2. Switch to "Vehicle self-diagnosis" mode and select the "Engine electronics" vehicle system (see section 5.3).

3. Switch the ignition on. If the connections are working data on the vehicle sy-stem variant will be displayed on the right side of the mask after a few secon-ds. If there is a break in the K-wire or the L-wire, the following message appears in the top left corner of the mask.

Vehicle not available.

If there is a break in the supply wire in a 3 meter diagnostic cable, this message appears:

No voltage or voltage too low on diagnostic bus.

.

The diagnostic cable and diagnostic adapter function tests described below may only be performed on fault-free vehicles, to ensure that tests return logical results.

.

When testing the 3 meter diagnostic cable, the tester should always be powered by way of the diagnostic cable from the vehicle electrical system (no mains power connection to the tester) so that the supply leads to the tester can also be tested. If the top LED on the tester is lit up in green, the connection is OK. If the LED is lit up or flashing yellow, the cable is defective.

Troubleshooting


Diagnostic adapter A diagnostic adapter function test is performed as follows:

If the test results do not conform to the required values, there is a fault in the diagnostic adapter. If this is the case, you should send in a fault report as shown in section 11.4.

1. Connect the tester to a vehicle via a fault-free 3 meter diagnostic cable and the diagnostic adapter.

2. Switch to "Vehicle self-diagnosis" mode and select the "Engine electronics" vehicle system (see section 5.3).



If there is a break in the supply wire in the diagnostic adapter, this message appears:



Troubleshooting

Diagnostic cable LT A diagnostic cable LT function test is performed as follows:

1. Connect the tester to a vehicle via the diagnostic cable LT.

2. Switch to "Vehicle Self-Diagnosis" mode and select the "Engine electronics" vehicle system (see section 5.3).



If there is a break in the supply wire in the LT diagnostic cable, this message appears:

Care and Maintenance


12 Care and Maintenance

12.1 Visual Check of the VAS 5051

You should carry out a visual check of the VAS 5051 on a regular basis. Check all parts for damage (e.g. fractures) and dirt contamination.

Check the touchscreen carefully for damage or dirt. Clean as shown in section 12.2.1 as necessary.

Regularly check all cables for damage.

12.2 Tester

If the casing is dirty, clean it with a non-fluffing damp (not wet!) cloth.

If the tester is damaged, contact the SIEMENS hotline (see section 14.2).

+

Always replace damaged cables.

+

Before cleaning the tester, as a safety measure switch it off and unplug it! Unplug all measuring leads. Be sure that no liquid gets into the casing. Do not try to clean the internal parts of the CD and floppy disk drives.



12.2.1 Cleaning the Touchscreen

The most sensitive component of the tester is the touchscreen. Its sensitivity to touch can be reduced by dirt or scratches. If it is dirty, clean it with a soft (as far as possible non-fluffing) cloth. If this fails to remove the dirt, you can use isopro-pyl alcohol or ammonia-free glass cleaner.

12.2.2 Forming the Battery

The battery has a typical lifespan of approx. 500 charge/discharge cycles. This can only be achieved if – whenever possible - you discharge the battery fully in every cycle, and if you form the battery once a month (that is, run it down and recharge it).

The battery should also be formed if the VAS 5051 has not been used for a long period of time, because the battery will self-discharge during that time.

To form the battery:

1. Disconnect the mains power from the tester without switching it off.

2. Leave the tester on until all the LEDs go out: the battery is now discharged.

3. Switch the tester off.

4. Plug it in to the mains to recharge the battery. It takes about 2 hours to charge it completely.

If the standby runtime of the battery falls below 30 minutes even after being formed repeatedly, it must be replaced.

+

Always replace a defective battery with a new battery. Never operate the unit without an installed battery.



12.2.3 Changing the Battery

You can find the order number and supplier of this consumable in section 11.6.

Change the battery as shown below:

1. Switch the tester off properly and unplug the power cable.

2. Lay the tester down on a level, clean, open surface with the screen facing down so that it cannot be damaged.

3. Open up the quick-release screw (fig. 12-1) using a slotted screwdriver (turning no more than 90° counterclockwise!).

4. Lift the cover of the battery compartment and take it off.

Fig. 12-1 Opening the battery compartment

5. Push the black plastic foam pad in the battery compartment to the left and re-move

6. Disconnect the connector from the battery cable. Press down the retaining spring in the middle of the two connector sections with your thumbnail and pull the sections apart (see fig. 12-2).

7. Replace the old battery with a new one.

8. Reconnect the connector. The plug must engage in the socket.

9. Replace the plastic foam padding in the compartment

10. Store the connecting cable with the connector in the battery compartment.

11. Take the cover and position it with its back edge under the panel of the sheet-metal casing. Close down the quick-release screw (fig. 12-1) using a slotted screwdriver (turning no more than 90° clockwise!).

12.2.4 Changing the Air Filter

If the red LED signals overheating, and in any case at least every three months, the air filter must be changed as a preventive measure.

1. Turn the tester off properly and unplug the power cable.

2. Lay the tester down on a level, clean, open surface with the screen facing down so that it cannot be damaged.

3. Open up the quick-release screw(fig. 12-3) using a slotted screwdriver (turning no more than 90° counterclockwise!).

Fig. 12-3 Removing the air filter

4. Remove the cover.

5. Pull out the filter.

.

Dispose of the battery in an environmentally friendly way.

Quick-release screwfor the air filter



6. Install the new filter.

7. Take the cover and position it with its back edge under the panel of the sheet-metal casing. Close down the quick-release screw (fig. 12-3) using a slotted screwdriver (turning no more than 90° clockwise!).

8. Switch on the tester.

If the red LED remains on, there is probably a fault. Send a fault report to the SIE-MENS Service Center (see section 11.4).

12.2.5 Changing the Fuse for Inline Current Measurement

The fuse on the top side of the tester breaks the current when the inline current measurement rises above 10 A. A replacement fuse is included with the tester when it is shipped.

To change the fuse:

1. Unscrew the cap from the fuse box (see fig. 12-4 ). The fuse is in the cap.

2. Remove the defective fuse.

Fig. 12-4 Removing the fuse

3. Place the new fuse in the cap.

4. Screw the cap back into the fuse box.

Cap of theFuse Box

+

Replace a defective fuse only with the original fuse included with the tester. Damage resulting from incorrect replacement fuses is not covered under the warranty.




The workshop trolley is maintenance-free.

12.4 Measuring Leads

Check all measuring leads for damage on a regular basis. Replace damaged leads.

12.5 Printer

Care and maintenance of the printer generally relates only to cleaning and con-sumption of toner and the drum unit. You do not need to grease or oil the printer mechanism.

The drum is a highly sensitive component. It has been protected against damage as much as possible. Nevertheless, you must handle it with the greatest possible care to keep it functioning properly.

+

Do not touch the green surface on the drum.Do not expose the drum to light for more than five minutes.Protect the drum against scratching.

+

The heating unit within the printer gets very hot during printing. You may burn your hands if you touch it. Wait until the heating unit has cooled before opening the printer casing.

+

Toner should not get on skin or clothing. If this does happen, use only cold water to remove the toner. Hot water could cause the toner to stick to skin or clothing.



12.5.1 Changing the Toner Cartridge

You can find the order number and supplier of the end-user part in section 11.6.

Change the toner cartridge as follows:


2. Pull the blue plastic catch on the right side of the toner cartridge toward you to release it (see fig. 12-5). Lift out the toner cartridge.

Fig. 12-5 Catch on toner cartridge

3. Unpack the new cartridge. Sealing tape on the underside of the cartridge pre-vents toner from running out. Remove the entire length of the tape.

4. With the opening facing down, insert the toner cartridge into the left side of the cartridge tray in the drum unit. The blue catch on the toner cartridge must be on the right. Press it into the tray until it lies flat in the printer.

5. Using a little bit of force, move the blue catch back all the way to lock the toner cartridge in the printer.

6. Clean the LED array as shown in section 12.5.3.



12.5.2 Changing the Drum Unit

If you see the message "Drum?" in the display field or if the print quality dimin-ishes, the drum unit should be changed at the next opportunity.

You can find the order number and supplier of this consumable in section 11.6.

Exchange the unit as follows:


Fig. 12-6 Removing the drum unit

2. Holding the drum unit at the front, lift it out of the printer together with the toner cartridge (see fig. 12-6).

3. Unpack the new drum unit, remove the foam packing and the white protecti-ve paper stuffing. Keep the foam packing in case you need it for transporta-tion.

4. Install the new drum unit. It must lie securely and level in the recess provided.

5. Install the toner cartridge as described in section 12.5.1.



6. Close the cover so that the release buttons lock.

7. Reset the drum unit counter:

− Hold down the "Menu 1/Menu 2" button on the button panel while swit-ching on the printer. The message "SERVICE1" appears in the display pa-nel.

− Press the "Menu 1/Menu 2" button three times. The function "RESET DRUM" must appear in the display field.

− Press the "Enter" button. After a short time, you see "ON-LINE HP4" in the display field.

8. Pack the old drum in the packing material of the new one and return it to your supplier. The drum will be recycled.

If the drum is not installed correctly, the printer will show this in the display field with the message "DRUM?".

12.5.3 Cleaning the LED Array

The LED array on the underside of the cover can become dirty when changing toner cartridges, or simply over time. Clean it as needed, but especially after

changing the toner cartridge, using the cleaning cloth included with every new toner cartridge (see fig. 12-7). You can also use a soft, non-fluffing cloth and a cleaning agent such as isopropyl alcohol, for example.

Fig. 12-7 Cleaning the LED array

+

The LED array may be damaged if you use an unsuitable cleaning agent.



12.5.4 Cleaning the Drum

If unused toner has settled on the drum, you can remove it using an internal cleaning procedure.

1. Switch the printer off-line by pressing the ON-LINE button.

2. Hold down both the/ /#/ /buttons simultaneously for more than two seconds until you see this message in the display field: "Clean, Add A4 Paper Manually".

3. Open the manual paper feed by pressing on the two markings and pulling it down.

Fig. 12-8 Inserting a sheet in the manual paper feed

4. Insert a DIN A4 sheet of paper in the manual paper feed. The printer draws it in automatically (see fig. 12-8). In the display panel you see the message "CLEAN PRINTER". The excess toner will come off on the cleaning sheet unevenly and the printer will print the words "The drum unit has been cleaned".

5. After the page has come out, switch the printer back on-line by pressing the ON-LINE button.

+

You cannot clean the drum by hand.



12.5.5



12.5.6 Cleaning the Printing Mechanism

To ensure that your printer operates smoothly, you should clean the printing mechanism as needed (at least every six months).

1. Remove the drum unit as shown in section 12.5.2. Pack it so that it is not ex-posed to any light.

2. Remove any leftover paper or dust with a soft brush or pencil brush. Do not use any solvents or strong cleaning agents.

3. Excess toner residue can only be removed with a vacuum cleaner fitted with a microfilter. Household vacuum cleaners should not be used.

4. Refit the drum unit as shown in section 12.5.2.

12.5.7 Printer Settings

The printer is customized for use with the VAS 5051 tester and is configured be-fore being shipped. The settings are given in the appendix to this chapter.

12.6 Calibration

According to ISO 9000 ff., the accuracy of all measuring devices affecting the quality of a task performed - in this case a maintenance and repair task - must be calibrated periodically.

The tester together with the measuring leads is calibrated for three years (see cer-tificate, chapter 1). After that the calibration must be repeated every two years.

Please contact your representative before this time runs out.

Adaption values Values stored in the control unit, which can be adapted to the vehicle in a fixed range.

Alphanumeric key-board

Keyboard by which numbers and text can be entered.

Amplitude The maximum value that the amount of deviation of an oscillation, e.g. a voltage, an alter-nating current, can reach.

Basic setting To permit settings to be made, the controls in the control unit are shut off and set to a basic value.

Buffered The power supply to the tester is buffered; that is, if the power fails or the tester is moved with its power cable disconnected, the installed accumulator provides the power supply for a limited time.

Calibration Determining the deviation of a test device (e.g.: current pick-up).

CD-ROM Compact Disk - Read Only Memory: A storage medium that looks like a music CD that can be read only; it cannot be written to.

Channel number Number of a measured value channel in the control unit.

COM: "Common"; corresponds to "Ground" or "0 V"; measurement device input

Control unit Electronic device to control and monitor vehicle functions. Vehicle system

Data block Display group.

Degree of suspicion The order in which diagnostic objects are suspected of having faults.

Deselection, deselec-ting

Canceling a selection of program functions or list entries. Selection.

Diagnosis The entire process of assigning fault characteristics to possible faulty functions, com-ponent groups or components until a faulty component is localized. Can be determined by retrieving expert knowledge from the knowledge base or from the user’s direct expert knowledge. The result of the process is also sometimes termed "diagnosis".

Diagnosis object Umbrella term for functions, component groups or components to which the diagnostic function is applied.

Diagnostic cable Connection cable between the vehicle and tester.

Diagnostic connec-tion

Connection socket for the diagnostic lead on the tester or vehicle

Diagnostic strategy Process of guided fault finding based on the available information about a fault such as1. fault codes read from vehicle systems,2.complaint reports (terms selected by the user from masks to describe symptoms or fault characteristics) or3. terms describing functions and components of the vehicle selected by the user from masks as possible fault sources; own test plan.The three entries, either individually or combined, lead to a calculated test proposal in the test plan. The strategies (1.) and (2.) are designated as system-guided fault finding, while (3.) is designated as user-guided fault finding.


Terms

Dialog box On-screen information box showing messages and expecting entries from the user.

Direct current measu-rement (inline current measurement)

Current measurement in which the tester is used as an ammeter directly in the circuit. Opposite: Inductive current measurement via a current pick-up clamped on the cable.

Display group A fixed group of data that can be read from the vehicle system.

Document Documents in the tester containing information (images, text) that can be used as needed by the user.

DSO Digital Storage Oscilloscope

Fault characteristics The entire effects (fault symptoms) of a fault scenario in vehicle functions, component groups or components.

Fault memory Data memory of the control unit in which all detected faults are stored.

Fault symptom A describable effect of a fault symptom in the vehicle functions, component groups or components. The symptoms make up the fault characteristics. Known symptoms assi-gned to suspect diagnostic objects are stored in the database of the tester. Diagnosis.

Floating No connection to the power supply or to the grounding.

Function Every action that the tester can take in the various operating modes. Individual functions usually are selected from a list displayed on-screen.

Function test A test program with which functions, component groups or components can be checked as to whether they meet requirements. The function test also can be used for a repair check.

Guided fault finding This covers the diagnostic process in an optimized procedure including vehicle identifica-tion, vehicle system test, test plan and function test.

Initial graphic Switchable image of a vehicle that appears in the start mask.

Inline current measu-rement

Direct current measurement.

IrDA Infrared Data Association.

Job code A unique combination of characters and letters to identify interrupted and saved diagnosis jobs.

Key CD CD on which the expanded functions are stored. It must be inserted in the tester’s drive to access the expanded functions.

Marque separation On devices with marque separation, only CDs for the vehicle marques required in the dealership in question need be installed on the tester. Without installation of at least one marque-specific CD the devices cannot run guided fault finding.

Mask On-screen display with pre-set breakdown into various graphical elements such as win-dows, buttons, scroll bars, etc.

Measurement type In "Test instrument" mode, the measurement type defines whether the measurement is executed with DC voltage or AC voltage. In "Guided Fault Finding" mode the measure-ment type determines whether a current or a voltage is measured in a function test.

Mode, Modes The current operating state of the tester, or its program.

Navigation bar Functions in the lower portion of the mask, e.g. switching from the current mask to another mask in guided fault finding.

Numeric keyboard Keyboard by which only numbers can be entered, no text.


Terms


Operating mode Any basic tester function that can be activated from the start mask: "Vehicle self-dia-gnosis", "Test instrument", "Guided Fault Finding", "Administration" and "Help". Each operating mode is divided into individual functions.

Operating system The software installed in the tester.

Oscilloscope Measurement and display device for electrical signals that displays the time characteristic of the signal strength (e.g. oscillations)

Own test plan Diagnostic strategy based on the selection of descriptions of possible defective functions and components by the user. If faults in the vehicle system are detected during diagnosis or a complaint report is entered, the test plan differentiates between the system test plan and an own test plan.

Permanent fault A continually occurring or continuous fault.

Preselection The suggestion of the tester to call up one of several functions from the current mask. The preselection is shown by a black bar on the screen. You can change it at any time.

Print screen (Hard-copy)

Paper printout of the screen contents ( masks, etc.)

Pull-up menu Selection menu that the tester displays on-screen when certain buttons on the navigation bar are chosen.

Quit Response to a query from the tester, resulting in termination of a function or dialog.

Reversed polarity Mistakenly switching the connection leads for the power supply.

Run-up Tester action between power-up and the first display of the start mask, which includes loading data, a self-test, etc. Tester run-up takes approximately 1.5 minutes, during which time no entries can be made.

Screensaver (standby mode)

Advanced Power Management (APM): If the touchscreen has not been used for ten minu-tes, the tester turns off the display to conserve energy. The operating system continues running. To activate the mask display, touch the top edge of the mask.

Selection bar Visual identifier of a selected line.

Selection, selecting Selecting a program function or a text entry from a list. The selected element is highligh-ted on-screen by a black bar. Deselection.

Self-diagnosis Vehicle systems are capable of making self-diagnoses. They have methods to check their own functions, connected sensors and actuators. A fault leads to an entry in the fault memory of the vehicle system. The tester has all faults in its knowledge base so that it can make a test proposal based on reading the fault memory and allocating a fault code to a fault type and location.

Sensor Device that picks up measured values.

Shutdown delay The time between pressing the on/off button to switch off the computer and the actual shutdown. The shutdown delay is approximately 10 seconds.

Signal tone Beep or whistle emitted by the tester when, for example, the battery voltage reaches a limit in buffer mode.

Sporadic fault An occasional or short-term fault.

Start mask The display on the screen after the tester starts operation. From here, the tester‘s operating modes can be accessed. Identifiable by the initial graphic.



Terms

Sub-mask Any of several mask displays that belong to the same function and allow selection of restricting criteria or subfunctions, for example. Sub-masks in the same function are very similar and show the same basic data as set in other sub-masks in their information win-dows.

Test plan In guided fault finding, table listing the diagnosis objects determined by generation of suspicions and by fault finding algorithm.

Touchscreen (touch-sensitive surface)

Mask that has a touch-sensitive surface. The hardware and software reacts when an object such as a finger touches the screen, recognizes the place touched and triggers the associa-ted function (e.g. a button). The touchscreen replaces externally connected input devices such as a keyboard, mouse, etc.

Trigger level Voltage value at which the measurement of a test signal characteristic is started.

Trigger signal The signal used to start the graphing process of a test signal characteristic.

Update New version of the knowledge base imported from CD.

Vehicle system A control unit known by name, including associated sensors, actuators and cabling.

Virtual keyboard The graphical display of a keyboard on the touchscreen. The individual buttons can be used by fingertip control just as with a real keyboard.
