Hva betyr feilkoden?
The fault code means that CEM has received two speed signals from the brake control module (BCM) that differ too much over several driving cycles in a row. CEM uses the comparison to decide whether the car is standing still, and this controls the steering column lock. The fault may lie in a damaged sensor or in the BCM.
Mulige årsaker
- Damaged sensor that measures speed
- Fault inside the BCM itself
Hva du kan gjøre
- 1Read the fault codes in the brake control module (BCM) first, since this code comes from there and clears once the root fault is fixed
- 2With the engine off and the car stationary, try locking and unlocking the steering column lock, and note whether it works
- 3Safety: the speed signal affects both braking and the steering lock. Have a workshop check the BCM and sensors with diagnostic equipment
- 4Do not replace the CEM unless a workshop has shown it is damaged, since the fault usually lies in a sensor or the BCM
Symptomer du kan merke4
- Steering column lock does not lock or unlock
- Message in the information display
- Starter motor does not turn over or the engine does not start
- Text window and warning symbol with a text message
