Was bedeutet der Fehlercode?

The CEM has registered that communication with the PSM is not working. The power seat may then stop working, and the memory function with automatic setting of the seat and mirrors may not occur. 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 PSM
Break in the earth wire to the PSM
Contact resistance in the terminals
Open circuit in the CAN wiring to the PSM

Was Sie tun können

1Run the seat with the adjustment controls and see whether it moves
2Check the fuse for the front seat in the passenger compartment fusebox
3Look for loose connectors and damage at the seat
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 continue the fault-tracing

Symptome, die Sie bemerken können2

Power seat does not operate at all
Automatic seat and mirror operation does not work
