What does this fault code mean?
The control module in the rear door on the passenger side supplies the central locking motor via a relay. The passenger door module receives information about the status of the relay from the rear door control module. The fault code is set if the voltage is too low or too high, or if the relay has jammed.
Possible causes
- Short-circuit to ground
- Short-circuit to supply voltage
- The relay has jammed
What you can do
- 1Check that the cable harness is not short-circuited to ground or supply voltage, for example by measuring with a multimeter
- 2Check that the physical lock in the door can be locked and unlocked easily
- 3Run the central locking from the button and check whether the fault code comes back
- 4The fault code indicates a damaged component in the control module in the rear door. Have a workshop replace it
- 5After the replacement, check that the fault is remedied by locking and unlocking the car again
Symptoms you may notice2
