Troubleshooting by means of this network should not be limited to a single control unit. In fact it implies diagnosis on several control units.

Each control unit can perform checks based on the information received from the other control units;

the use of the CAN protocol enables to simplify the electric systems of the motorcycles, making them more reliable;

fewer sensors are needed;

optionals can be installed without changing the electric system of the motorcycle completely.


THE CAN NETWORK: CHARACTERISTICS AND ADVANTAGES

The most common version features 2 twisted wires to reduce sensitivity to electromagnetic interferences.

The two wires are called • CAN H • CAN L

Each node analyses the difference between the two signals.

CAN: Physical level

0 V corresponds to logic level 1 while 2 V to logic level 0.

This ensures signal quality and insensitivity to noise or interference.

DIAGNOSIS OF A MULTIPLEXING NETWORK

Generally, a CAN network fault may be due to: node faults; conductor faults; node power supply issues.

1) CAN H/CAN L interruption2) Short-circuit to ground - CAN H/CAN L3) Short-circuit - CAN H CAN L4) Short-circuit to positive - CAN H/CAN L5) Short-circuit to ground of the two conductors6) Short-circuit to positive of the two conductors


As each Bus has 2 120Ω resistances, their parallel value is 60Ω.This means that, when connecting a multimeter to the ends of the 2 wires, the rated value read should be 60Ω (55÷65Ω).

The checks can be carried out using:• an ohmmeter;• a voltmeter;• an oscilloscope.

Fault analysis on the road through the LOG function

It is possible to record the tests by using directly the DDS 2.0 software while it is performing a diagnosis on the selected system.The first step consists in choosing the 8 parameters that you wish to analyse.

The selected parameters must be calibrated according to the device to be analysed. Once the setting is complete, press the RECORD push-button to start recording.


Why should we divide the parameters in a group to record the data while we are performing a reading with the self-diagnosis?

Logical order of reading: Dividing the parameters in logical groups allows to display simultaneously all the data referring to a component or a system to be tested (e.g. lambda sensors)

Analysis of the data over time: Often, the instantaneous reading does not clearly indicate the trend of a specific parameter, and above all it does not facilitate the comparison of several parameters read simultaneously but occurring at different times.

Storing a case: All records are stored «forever» in a DDS 2.0 personal database, where it is possible to retrieve the history of the analyses performed on a specific vehicle. Even more important is the fact that such analyses represent valuable information for comparing the data with other similar vehicles.

Use of DMT tool


Keep POWER pressed for more than 3 seconds to turn on the tool

The tool automatically recognises the type of probe connected and displays the relevant menu with the available functions.

The current tests with the DMT should always be considered solely to analyse the absorption of the electric system of a motorcycle with key on OFF. Maximum current read by this tool is 10 mA.

The current test menu includes the functions: Ammeter, instantaneous reading of the value of

the current absorbed by the motorcycle. Check, preliminary current absorption test on a

motorcycle in key-off status.

Use of DMT tool


Prior to initiating the reading, the menu will prompt operator to check whether the motorcycle is in the key-off status. After that, a 90 second countdown will be started in order for the control units to perform the power latch phase

At the end of countdown, the tool starts measuring the current.

TEST PASSTest successfully carried out.

The current absorption is below the maximum threshold required. Carry out measuring all the same, using the ammeter menu and fill in an information report on Youtech.

TEST CHECKThe test shows "faulty" absorptions. It is necessary to check the motorcycle electric system to find out the cause for the excessive current absorption. Try to recharge the battery and fill in the relevant assistance or pre-approval request on Youtech.

Use of DMT tool


Disconnect the battery system negative pole and fit the DMT cable in series connection between the battery and the negative pole itself.

Guide for filling out the diagnosis technical report


What are the advantages of a standard diagnosis mode?

Repeatability (same method independently of the fault) Fast identification of the fault Certainty of the diagnosis (reduces the risk of useless

replacements)

The aim of this form is to encourage the organisation of a diagnostic process. The participant

has to fill in the form completely. The diagnostic path can be summarised in 7 steps:

1. collecting the information about the motorcycle and the condition of the instrument panel.

2. Scanning the motorcycle electronic system: GLOBAL SCAN

3. Specific diagnosis of the control unit showing the fault or connected to the signalled fault

4. Check DTC for any SAT bulletins or TIPS relevant to the fault under test

5. Electric diagnosis of the components

6. Electric diagnosis of the battery absorption condition in key-off status7. Final considerations and solution


First of all, what is needed to start a correct diagnosis? Collecting all the information about model and outfitting Collect the information relevant to the fault reported by the customer

Missing ABS Bosch -- / -- 0 NO



The data collected by the Global Scan, the information from the customer and the info read on the instrument panel will give an indication on where to start the check.

The main operations to consider are:1) self-diagnosis, using DDS2.0 for the control unit showing ATT (live) or MEM

(stored) errors

2) electric tests by checking voltage, current, resistance and continuity by means of a multimeter

3) electric tests by checking the current absorbed by the motorcycle in key-off using the DMT tool.



The step following Global Scan consists in selecting the control unit from which the self-diagnosis should be started and in filling in completely the table of unit 2.Besides the list of errors, the following fields - which are essential for a correct diagnosis - must be present and must be completed.

• ECU info• Engineering parameters• Statuses• Activations• Settings.

Use the activation page to find out whether any of the actuators is not working properly. Warning: in case of errors on the actuators, some of the activations may not be available. Complete the settings field with the info on what has to be used after fixing the fault.

After checking for faults in the control units as described above in unit 2, now check if any SAT service bulletins and/or Tips&Tricks referring to the signalled problem or to the diagnosed errors are available:

3 Check availability of SAT TB and/or Tips&Tricks

YES



Relying on the information collected and the checks carried out in the units as described above, assess whether it is necessary to perform one or more electric tests using a multimeter:

It is a good practice to carry out general checks when examining an electric system, such as check of fuses, power supply and ground points of control units and actuators. Besides, check electric continuity of the affected wiring branches.

6 Fault fix - Final comments

In this final part, divide the comments to the case study in three points:

1. Further symptoms: accurate listing of all the symptoms detected besides the reported fault

2. Causes for the fault: describe what is generating the conditions for the fault being analysed

3. List of corrective measures to fix the fault
