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.

Technical modifications may be introduced at any time. Observe model-specific diagnostic information and any applicable service bulletins for updates.
