Hva betyr feilkoden?
The brake control module (BCM) has registered that the voltage supplied to the ABS pump motor is incorrect. The pump motor sits in the hydraulic unit and builds the brake pressure needed for ABS, stability control and brake assist. The check only runs once the car has been moving, so the fault is usually noticed while driving.
Mulige årsaker
- Poor contact in the connections
- Blown fuse for the pump motor
- Open circuit in the supply wire to the pump motor
- Open circuit in the pump motor's ground wire
- Defective pump motor
- Faulty brake control module (uncommon)
Hva du kan gjøre
- 1Check the pump motor fuse in the engine bay relay and fuse box; if it has failed, test the circuit beyond it before fitting a new one
- 2Check the connectors at the brake control module and the pump motor for contact resistance and oxidation
- 3Run the pump motor with diagnostic equipment and check that it starts and runs normally
- 4The brake system is safety critical: do not work on the hydraulic unit or pump motor yourself; have a workshop repair the fault
Symptomer du kan merke5
- General warning lamp on
- ABS warning lamp on
- ABS, traction control and stability function do not work
- Anti-skid does not work
- Information lamp on
Hva feilen kan påvirke2
- ABS, traction control, stability control and brake assist are disabled
- The brakes still work but without ABS regulation
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
