Co oznacza ten kod błędu?
The driver and passenger door modules continuously check the signal from the switch for the electric window lift of the rear window. The fault is stored when the signal from the switch has been active for a long time, for example if the switch is stuck, or when the signal wire has been short-circuited to ground for a long time. The module then ignores the signal until the switch is no longer pressed.
Możliwe przyczyny
- The switch is stuck in the pressed position
- The signal wire is short-circuited to ground
- Moisture and/or oxidation in the connections
- The local window switch is damaged
Co możesz zrobić
- 1Check that the switch in the door can be pressed in and released, and that it is not stuck
- 2Check that the fuses are intact
- 3Test the other window switches in the door and see whether only the switch for the rear window fails
- 4Check the connector to the switch for moisture and oxidation
- 5Use a multimeter to check that the signal wire has no contact with ground
- 6If the fault remains, have a workshop with diagnostic equipment check the switch and the control module
