Hva betyr feilkoden?
The code indicates an internal system fault where the checksum of the speed signal does not match. The brake control module (BCM) registers the fault, passes it on to the engine control module (ECM) and also stores a fault code of its own. The malfunction indicator lamp (MIL) may light up.
Mulige årsaker
- Faulty speed input to the brake control module (BCM)
Hva du kan gjøre
- 1Read the fault codes in the brake control module with a diagnostic tool, and remedy them first
- 2Check that the battery voltage is good and that the fuses are intact. Their location is given in the owner's manual
- 3Check that the speedometer works normally during a test drive
- 4The brake system is safety-critical: have a workshop check the wheel sensors, the wiring and the brake control module. Do not work on the brakes yourself
- 5Clear the fault code once the fault has been remedied, and road test
Symptomer du kan merke1
- The malfunction indicator lamp (MIL) lights up
Hva feilen kan påvirke1
- the brake module speed signal is replaced by a fixed value
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
