K. Version Coding

1. Connect Star Diagnosis to the vehicle and perform the following version coding.

2. Set the MOST ring configuration to match Figure 60 via path:

Control units > Information and communication > Audio, video, navigation and telematics > COMAND with integrated Audio Gateway > Retrofitting of MOST components > F2: Restart of optical ring > F2: Actual configuration > Verify that "Telecommunications" is listed under Actual Value and configuration of the MOST components matches that of Figure 60 > F2: To continue > F3: Yes, to write the current actual configuration to MOST master > F2: Erase fault memory

Note:
The MOST ring configuration in Figure 60 is an example of a configuration including every component. Some installations will not include all the components shown in the example. If a component is not present, connect the preceding component to the component following the one not present.

NOTICE!

Match the MOST ring configuration to Figure 60.

Failure to have the configuration match Figure 60 will result in erroneous system operation and/or intermittent malfunctioning of some or all components in the ring.

DO NOT alter the configuration in Figure 60 to match the vehicle configuration.

3. Set the Tele Aid control module to recognize presence of the telephone via path:

Control units > Information and communication > Audio, video, navigation and telematics > TELE-AID > Control unit adaptations > Model series, telephone adapter for portable CTEL (MHI) > Set "Model series" to W203, Set "Telephone adapter" to FITTED, press F5 > F3: Yes/Coding > F2 to confirm the coding was carried out

4. Reset the control module via path:

Control units> Information and communication > Audio, video, navigation and telematics> TELE-AID > Control unit adaptations> Reset control unit

5. Set the Tele Aid in the EIS via path:

Control units> Body> EIS > Control unit adaptations > Read coding and change if necessary > Set status CAN bus > Set "CAN bus: Control unit TELE AID or E-CALL" to PRESENT, then press F3 > F3: Yes/Coding > F2 to confirm the coding was carried out

6. Check the DTC memory of all installed components and the head unit. Investigate and identify any present DTCs. Once identified, correct the source of the DTCs and clear the DTC memory.

Note:
Powering up the newly installed system prior to version coding will set errors in the MOST ring configuration. Ignore these errors during the initial DTC check. If the DTCs return after clearing, a configuration error is present. Locate and correct the error.

7. Confirm no new DTCs are present in the MOST system group.
