G. Version Coding and Diagnostic Testing

1. Connect StarDiagnosis (SDS) to the vehicle and perform the version coding outlined below.

2. Using path: Control units/Information and communication/ICM/Control unit adaptations/Standard version coding/Optional equipment, set CTEL = Exists.

3. The electronic ignition switch (EIS) must be version coded to indicate the presence of the VCS module.





4. Using path: Control units/Information and communication/D2B/Control unit adaptations/Read coding and change If necessary/Specified configuration of D2B components, set the D2B ring configuration to match the diagram.

Note:
The diagram is an example of a D2B ring configuration including all components. Some installations will not include all of the components shown in the example. If a component is not present, connect the preceding component to the one following the component not present. Vehicles with COMAND include the Tele Aid 2 module in the D2B ring. Refer to S-SI-82.64/135, D2B Fiber Optic Configuration and Version Coding for proper handling and configuration of D2B fibers.

5. Return to the D2B functions menu. Using path: Actual values/Actual configuration of D2B components, verify that the above version coding input (specified value) matches the actual configuration performed during installation (actual values). If a difference exists, the ring has been improperly configured and must be disassembled to diagnose and correct the error.

NOTICE:
DO NOT alter the configuration in the diagram to match the vehicle configuration. Failure to have the configuration set as indicated in the diagram will result in erroneous system operation and/or intermittent functioning of some or all components.

6. Check the DTC memory of all installed components and the head unit. Any present DTC(s) should be investigated, the source identified, corrected, and the DTC memory cleared.

Note:
Powering up the newly installed system prior to the above described version coding will set D2B ring configuration errors. These errors may be ignored during the initial DTC check. If, after clearing the DTC(s), they return in the next step, a configuration error that must be located and corrected has occurred.

7. Confirm that no new DTC(s) have been set in the D2B system group.
