Was bedeutet der Fehlercode?
The driver and passenger door modules (DDM/PDM) check the signal from the central locking unlock button inside the door. If the button has been held in for a long time, or if the signal cable is shorted to ground, the code is set. The module then ignores the signal until a button that is not pressed is detected.
Mögliche Ursachen
- The button has jammed in the pressed-in position
- The signal cable is shorted to ground
- Moisture and/or oxidation in the connections
- Damaged local lock control
Was Sie tun können
- 1Read the code, clear it and check that the button returns when released and does not stick
- 2Check the fuses in the fuse box and make sure they are intact
- 3Check that the button is secure in the door panel and that the connectors behind it are free from moisture and oxidation
- 4Use a multimeter to check that the wire to the button has no contact with ground (the body)
- 5If you have diagnostic equipment, read the button signal in live data and check that it returns to the not-pressed state when released
- 6If the fault remains: have a workshop check the lock control and the door module
