Was bedeutet der Fehlercode?

The CEM has registered that communication with the driver door module (DDM) is not working. A door may then not lock or unlock from the driver's switches, and the driver's switch panel may stop working. The fault code points to a communication fault in the CAN network, so the CEM should not be replaced.

Mögliche Ursachen

No power supply to the DDM
Break in the earth wire to the DDM
Contact resistance in the terminals
Open circuit in the CAN wiring to the DDM
The DDM is not meant for this car, for example a used module with other software or hardware

Was Sie tun können

1Test the window switches up and down and the central locking buttons with the ignition on
2Check the fuse for the DDM in the passenger compartment fusebox
3Look for chafed wires or loose connectors at the driver's door
4If you have a diagnostic tool, read the module ID; if it can be read, communication is probably fine and the fault may be intermittent
5If the fault remains, have a workshop troubleshoot the CAN wiring

Symptome, die Sie bemerken können2

Does not lock or unlock a door
