Hva betyr feilkoden?
The CEM controls locking and unlocking of the door lock motors and gets their positions from the door modules over the CAN network. For the passenger side rear door, the information comes through the passenger door module (PDM). The code is stored when the deadlock motor is not confirmed in the requested position after locking or unlocking, so the rear door does not lock as it should.
Mulige årsaker
- Lost signal exchange with the passenger door module (PDM)
Hva du kan gjøre
- 1If you have a diagnostic tool: read the fault codes in the driver and passenger door modules (DDM and PDM) and note them
- 2Test locking a few times with the remote and see which doors respond. Locking many times in a row can make the motors temporarily hot, so wait a while
- 3Activate the deadlock and listen for a clicking sound from all doors. If only the passenger side rear door is silent, the fault is most likely in that lock or its wiring
- 4Look for chafing and loose connectors in the wiring between the passenger door module and the lock. This needs the door trim removed, so let a workshop do it
- 5If the fault returns, have a workshop with diagnostic equipment check the module and update its software or replace the lock
Symptomer du kan merke1
- Passenger side rear door will not lock or unlock when activated and deactivated
