What does this fault code mean?
The control module in the driver's side rear door supplies the central lock. When the central locking is activated, the output signal becomes too low, because the supply cable is short-circuited to ground. The rear door then does not lock or unlock.
Possible causes
- Supply cable short-circuited to ground
What you can do
- 1Test the central locking with the button and note which doors do not respond
- 2With ignition off, use a multimeter to confirm the supply cable to the rear door lock motor has no contact with ground (body). Replace the cable if it is damaged
- 3Check the connectors in the rear door for moisture, oxidation and loose contacts
- 4If the fault remains, have a workshop replace the control module in the rear door
