Diagnosis instructions
Swapping with control units from other vehicles is not possible. The Rear Electronic Module (REM) can only be ordered as a new part. The Rear Electronic Module (REM) is supplied encoded for the vehicle.
Notice! Follow the instructions for service functions!
After installing a new Rear Electronic Module (REM), start-up must be carried out with the help of the diagnosis system. For example, the rear power window regulators must be initialized.
NOTE:
Technical modifications may be introduced at any time. Observe model-specific service information and any applicable service bulletins for updates or changes.
