Co oznacza ten kod błędu?
The rear door module controls the central locking and the child safety lock through a relay on a shared output. The module in the rear door also informs the driver and passenger door modules about the relay status. The fault is stored when the supply is too low or too high, or when the relay is stuck. The locks in the rear doors may then not work correctly.
Możliwe przyczyny
- Short circuit to ground
- Short circuit to supply voltage
- The relay is stuck
Co możesz zrobić
- 1Check that the fuses are intact
- 2Check that the locks in the rear doors can be locked and unlocked by hand, and that nothing is stiff mechanically
- 3Inspect the wiring harness to the lock motors in the rear doors for a short to ground or supply voltage, and check that the connectors are secure
- 4Read and clear the code, road test and see whether it returns
- 5The code points to a damaged component in the rear door module: have a workshop replace the module and confirm that the fault is cleared
