Was bedeutet der Fehlercode?
The child lock in the passenger side rear door has its own lock motor. When the function is on, the inner door handles are disengaged and the power windows in the rear doors are disabled. The code is stored when the lock motor has not reached its locked or unlocked position after two attempts, which means the child lock does not work.
Mögliche Ursachen
- Damaged switch that shows the lock motor position
- The lock motor is stuck
Was Sie tun können
- 1If you have a diagnostic tool: read the fault codes in the driver and passenger door modules (DDM and PDM)
- 2Turn the child lock on with the driver door switch. Then the rear door should not open from inside, and the rear windows should not respond
- 3Check that the relevant fuses are intact, especially the fuse for the right rear door module in the rear relay and fuse box
- 4If the fuse has blown, use a multimeter to check the wire is not shorted to ground before replacing the fuse
- 5Look for mechanical obstructions that could block the lock motor, and check that the lock moves freely
- 6If the fault returns, have a workshop check the wiring and replace the lock unit if needed
