Co oznacza ten kod błędu?
The keyless vehicle module (KVM) watches the shared ground wire for the lock and unlock sensors in the outer door handles. The code is stored when that wire reads constantly low, which means it is not getting a proper ground. Locking, unlocking and central locking then do not work, and the fault can appear while the engine runs and the car is driven.
Możliwe przyczyny
- The wire is shorted to ground
- Open circuit in the wire
Co możesz zrobić
- 1Read and clear the code, then run the engine to see whether it comes back
- 2Check the fuse for the circuit
- 3With the ignition off, use a multimeter to check the shared ground wire for an open circuit or a short to ground
- 4With a diagnostic tool, read the shared ground wire status in live data while locking and unlocking with the remote
- 5Have a workshop check the wire and replace the KVM if the fault remains once the wire is sound
