What does this fault code mean?
The driver door module (DDM) has not received a message from the switch panel in the driver door over the LIN communication, although one should arrive. The fault points to an interrupted or shorted communication wire or a poor connection. Because the controls cannot be read, several driver door functions stop working.
Possible causes
- Break in the communication wire
- Communication wire shorted to ground or to voltage
- Contact resistance, oxidation or a loose connection in the connections
What you can do
- 1Read and erase the code, then road test to see whether it returns
- 2Check that the fuses are intact
- 3Test the driver door functions one at a time and note whether all the controls have stopped or only some
- 4Check the connectors and the wire between the switch panel and the door module for loose connections, chafing and corrosion
- 5Use a multimeter to check that the communication wire has no contact with ground (the body) when it is disconnected at both ends
- 6If the code comes back, have a workshop with diagnostic equipment check the LIN communication wire
Symptoms you may notice4
- Electric adjustment of the door mirrors does not work
