Was bedeutet der Fehlercode?
The door module (DDM/PDM) compares its own system voltage against the CEM voltage. The fault is stored when the two do not match, which can be caused by a short circuit to ground, too low supply voltage, or moisture and oxidation in the connections. The code is only worth troubleshooting if it has been active for a long time during the current drive or if you notice malfunctions. Otherwise it does not indicate a fault and can simply be cleared.
Mögliche Ursachen
- Power supply wiring short-circuited to ground
- Supply voltage too low
- Moisture and/or oxidation in the connections
Was Sie tun können
- 1Read and note the code, clear it and road test the car; if none of the problems above apply, the code can be cleared without further action
- 2Check that the fuses are intact; see the owner's manual for where they are
- 3Check that the battery is in good condition and the alternator is charging, and that the earth connection to the door module is secure and free from oxidation
- 4Check that the wiring to the door module has no chafing or short circuit to ground, and that the connectors are dry and clean
- 5If you have a diagnostic tool: follow the system voltage in live data while you activate the windows and mirrors, and check that it stays steady
- 6Have a workshop with diagnostic equipment compare the door module voltage with the CEM voltage if the fault remains
Symptome, die Sie bemerken können5
- Electric windows do not work
- The door mirror defrost does not work
- The windows work reduced or incorrectly
- Locking, unlocking and central locking do not work
- Doors and child lock do not work
