Co oznacza ten kod błędu?
The control module in the rear door supplies the central locking and the child safety lock through a common pole and a relay. The driver or passenger door module receives information about the relay status from the rear door control modules. The fault code is set when the voltage is too low or too high, or when the relay has jammed.
Możliwe przyczyny
- Short-circuit to ground
- Short-circuit to supply voltage
- The relay has jammed
Co możesz zrobić
- 1Use a multimeter on the cable harness to the rear door to check that it is not short-circuited to ground or supply voltage
- 2Check that the physical lock in the door moves easily by hand
- 3Test the central locking and see whether the fault code returns
- 4The fault code indicates a damaged component in the control module in the rear door. Have a workshop replace it
- 5After the replacement, lock and unlock the car to check that the fault code does not return
Objawy, które możesz zauważyć2
- Locking, unlocking and central locking do not work
- Child lock on the doors does not work
Na co może wpływać usterka1
