Reason for change Validity, complaint and symptom supplemented
Complaint:
Various function failures in the door control (only front doors affected):
^ Automatic window raising not possible
^ Power window cannot be normalized
^ Automatic fold in/out function of outside mirror faulty
^ Malfunction of central locking
^ Actuation of illumination in doors faulty
^ Malfunction of seat adjustment
Notes:
^ The fault memory of the door control unit (DCU-xF) may contain stored fault codes that are listed under "Control unit/fault code" (see below).
^ In the event of a complaint, the fault is continuously present.
Cause:
Waking of the door control units with a simultaneous voltage dip in the power supply (< 5 V) can cause the above function failures under certain
circumstances.
Remedy:
1. Perform reset of affected door control unit (unplug connector 3 at DCU-xF for approx. 20 seconds)
2. Perform normalization of power window system.
3. Erase fault memory.
4. Check whether the fault was rectified by the reset.
=> Fault not rectified: Continue with step 5.
=> Fault rectified: Continue with step 6.
5. Replace door control unit (DCU-xF).
