Hva betyr feilkoden?
The brake control module (BCM) has registered that the right front wheel behaves implausibly compared with the other wheels, for example stopping, turning too slowly or changing speed too quickly. The cause usually lies in the mechanics around the wheel, such as the brake or the wheel bearing. The code can only be diagnosed while the car is being driven.
Mulige årsaker
- The wheel locked while driving, for example due to a sticking brake caliper
- Loose wheel sensor or incorrect gap between sensor and tone ring
- Wheel bearing play or axle vibration
- Defective or dirty tone ring
- Defective wheel sensor
- Dirt between the tone ring and the wheel sensor
Hva du kan gjøre
- 1Check that the brake caliper on the right front wheel is not sticking and that the wheel turns freely
- 2Check the wheel bearing for play and noise
- 3Check that the wheel sensor sits firmly against the spindle or hub with no dirt underneath
- 4Check that the magnetic tone ring is securely fitted and complete, with no scratches or missing teeth
- 5Clear the code and road test; if it returns, have a workshop check the sensor with diagnostic equipment. Do not replace the brake control module because of this code
- 6The brake system is safety critical: the brakes work without ABS, so avoid hard braking until the fault is fixed
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
- With an intermittent fault the ABS lamp may only go out some way into the next drive
Hva feilen kan påvirke3
- ABS, traction control and stability control are disabled
- Electronic brake force distribution (EBD) is disabled if two or more wheel sensors have failed
- Brake assist and active yaw control (AYC) are disabled
