Was bedeutet der Fehlercode?
The driver door module receives, over the LIN bus, a signal from the rear door modules and from the control panel in the driver door that it does not accept as valid. The fault is stored when the signal is incorrect, and the cause lies in the module that sends the signal rather than in the driver door module.
Mögliche Ursachen
- The cause lies in the sending module, that is the rear door module or the control panel in the driver door
Was Sie tun können
- 1Read and clear the code and road test with the engine running to see whether it returns
- 2Check that the fuses are intact
- 3Check that the connectors in the driver door and the rear door are secure and free from corrosion
- 4Try the control panel in the driver door and the window switch in the rear door and see whether the fault follows one or the other
- 5If the fault remains, have a workshop with diagnostic equipment determine which sending module gives the faulty signal and repair it
Symptome, die Sie bemerken können2
- The control panel in the driver door does not work
- The electric window lift in the rear door does not work
