Replacing The Upper Electronic Module (UEM), Or The Rear View Mirror

PREPARATIONS 

NOTE: Read off data from the control module before replacing the control module. Program this data back into the new control module.

Programmed data is read off via VIDA vehicle communication.

CAUTION: New software can only be ordered when the control module is installed in the car. VIDA reads off the new control module identity which is required to order the correct software.

Always check the control module and connector on the control module box for bent or damaged pins or sockets. This may have caused the fault.
