Co oznacza ten kod błędu?
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.
Możliwe przyczyny
