Hva betyr feilkoden?
The brake control module (BCM) has detected a short to battery voltage or an open circuit in the circuit to the wheel speed sensor at the left front wheel. The sensor is needed for ABS and several stability functions, so these are affected when the signal is missing. The fault most often lies in the wiring, a connector or the sensor.
Mulige årsaker
- Contact resistance or oxidation in the connections
- Open circuit in the supply or signal wire
- Supply wire shorted to ground
- Wires shorted to each other
- Damaged wheel speed sensor
Hva du kan gjøre
- 1Check that the fuses are intact; their locations are in the owner's manual or on the fuse box cover
- 2Read and note the code, clear it and road test the car to see whether it returns
- 3Check the connector at the wheel sensor and at the brake control module for oxidation and contact resistance
- 4Follow the cable from the sensor into the wheel arch and check for breaks, chafing and a short to battery voltage or ground
- 5Check the signal with diagnostic equipment and replace the sensor or wiring as needed
- 6The braking system is safety critical: do not work on the wheel sensor or braking system yourself; leave this to a workshop
Symptomer du kan merke5
- ABS warning lamp and brake system warning lamp on
- Traction control warning lamp on
- Traction control does not work
- Stability function does not work
- Anti-spin function does not work
Hva feilen kan påvirke2
- ABS, traction control, stability control and brake assistance can be disabled
- Active yaw control (AYC) is blocked
