What does this fault code mean?
The PDM talks to the rear door on the passenger side over LIN, a standardised serial communication method. The module has registered that the signal from the rear door is missing, and the code is set as a result.
Possible causes
- Open circuit in the communication cable
- Communication cable is shorted to ground
- Communication cable is shorted to supply voltage
- Contact resistance, oxidation or poor contact in the connections
What you can do
- 1Read the code, clear it and run a test drive to see whether it comes back
- 2Check the fuses in the fuse box and make sure they are intact
- 3Check the connectors in the rear door on the passenger side and at the door module for moisture, oxidation and loose contact
- 4Use a multimeter to check that the cable between the door module and the rear door is intact and not shorted to ground or voltage
- 5If the wire is intact but the code comes back: have a workshop check the rear door control module
Symptoms you may notice4
