Hva betyr feilkoden?
Although the code is titled as a key lock switch, it applies to the front door lock motors. The driver and passenger door modules (DDM/PDM) receive information on whether each lock motor is locked or unlocked. The code is set if lock and unlock commands show up together, which means the signal does not add up.
Mulige årsaker
- An internal fault in the control module
Hva du kan gjøre
- 1Read the code, clear it and lock and unlock the car with the key to see whether the code comes back
- 2Check the fuses for the central locking in the fuse box and make sure they are intact
- 3Check that the lock motor in the door that does not lock or unlock is secure and that its connector is free from moisture and oxidation
- 4If you have diagnostic equipment, read the lock motor status in live data and check that it shows locked or unlocked when you lock and unlock
- 5If the fault remains: have a workshop check the lock motors and the door module
Symptomer du kan merke1
- One door does not lock or unlock
