Co oznacza ten kod błędu?
The movement sensor for the alarm gives a signal that is short-circuited, either to voltage or to ground. This can make the battery discharge abnormally fast, and the control module logs the fault when the sensor signal is wrong. The fault can be checked by locking the car with the remote key.
Możliwe przyczyny
- The signal is short-circuited to voltage or ground
Co możesz zrobić
- 1Disconnect any battery charger, and close the doors, bonnet and tailgate before testing
- 2Lock the car with the remote key and see whether the fault code returns. If it does, the fault is still present
- 3Check the wiring to the movement sensor for chafing and that the connector is secure
- 4If no fault is found in the wiring, have a workshop replace the movement sensor
Objawy, które możesz zauważyć4
