Hva betyr feilkoden?
The code concerns the speed sensor. The fault is registered in the brake control module (BCM), which sends the information to the engine control module (ECM) over the CAN network. The code does not specify the cause, but the fault lies in the speed signal from the brake system.
Mulige årsaker
- The cause lies in the brake control module (BCM)
Hva du kan gjøre
