What does this fault code mean?
The driver door module (DDM) continuously receives the information it needs from the passenger door module (PDM) over CAN. If the passenger side button for locking and unlocking the central locking is held in for a long time, or if its signal is missing, the code is set.
Possible causes
- Button has jammed in the pressed-in position
- Open circuit on the signal line between the passenger side button and the passenger door module
What you can do
- 1Read and clear the code, then check that the passenger side button returns when released and does not stick
- 2Check the fuses in the fuse box and make sure they are intact
- 3Check that the button is secure in the door panel and that the connectors behind it are free from moisture and oxidation
- 4If you have diagnostic equipment, read the button signal in live data and check that it returns to the not-pressed state when released
- 5If the fault remains: have a workshop check the button and the passenger door module
Symptoms you may notice2
- Central locking with the button in the door panel does not work
- Locking and unlocking with the central locking does not work
