Hva betyr feilkoden?
Each outer door handle has one sensor for locking and one for unlocking, and the keyless vehicle module (KVM) reads them. The code is stored when the module receives no lock signal, or a wrong one, from the handle behind the right rear door. Locking, unlocking and central locking from that handle then do not work, and the fault shows up while the engine runs and the car moves fast enough.
Mulige årsaker
- The signal wire has a short to supply voltage
- The signal wire has a short to ground
- Open circuit in the signal wire
Hva du kan gjøre
- 1Read and note the code, clear it and run the engine to see whether it returns
- 2Check the fuse for the circuit
- 3With the ignition off, check with a multimeter that the common handle-sensor ground wire is not shorted to supply voltage or ground
- 4Use a multimeter to check that the wires between the right rear handle and the KVM have no open circuit and no short to supply voltage or ground
- 5If you have a diagnostic tool: check the lock sensor in live data and see that the value changes when you press and release the lock button on the handle
- 6Have a workshop replace the handle if the wiring is sound, and the KVM if the fault stays. If the fault remains after the handle is replaced, the KVM may need replacing
Symptomer du kan merke1
- Locking, unlocking and central locking do not work
