G. Version Coding & Diagnostic Testing

G. Version coding and diagnostic testing

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

2. Using path:

Control units / Information and communication / D2B / Control unit adaptations / Read coding & 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 components shown in the example. If a component is not present, connect the preceding component to the one following the component not present. Only vehicles with COMAND include the Tele Aid module in the D2B ring. Refer to S-B-82.70/135B, "D2B Fiber Optic Configuration and Version Coding" for proper handling and configuration of D2B fibers.

3. For enlarged telephone functionality on COMAND, use path:

Control units / Information and communication / D2B / Control unit adaptations / Read coding and change if necessary / Configuration of components (Not D2B)

Double-click "Telephone with enlarged functionality." Then change the setting to "Installed" and transfer the coding to the control module.

4. Return to the "D2B Functions" menu. Using path:

Actual values / D2B Actual configuration

Verify the version coding input above (specified value) matches the actual configuration performed during installation (actual values). The configuration is wrong if a difference exists. In such a case disassemble and then properly reconfigure the ring.

5. For telephone functionality on the instrument cluster display, use path:

Control units / Information and communication / ICM / Control unit adaptations / Version coding / Optional equipment

Set Cellular Telephone to "PRESENT."

NOTICE
DO NOT alter the configuration in step 2 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 malfunctioning 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 before version coding will set D2B ring configuration errors. Ignore these errors during the initial DTC check. If after clearing the DTC(s) they return in the next step, a configuration error is present that must be located and corrected.

7. Confirm no new DTC(s) exist in the D2B system group.
