Was bedeutet der Fehlercode?
The brake control module (BCM) has registered that the signal from the left front wheel sensor is disturbed or interrupted on many occasions. The sensor reads a toothed ring on the wheel axle. The cause may be a loose sensor, damaged wiring, a defective tone ring or dirt between the ring and the sensor. The fault can be diagnosed while driving.
Mögliche Ursachen
- Loose wheel sensor
- Damaged wiring
- Defective tone ring
- Dirt between the tone ring and the wheel sensor
Was Sie tun können
- 1Check that the wheel sensor sits firmly against the spindle or hub with no dirt between sensor and mounting face
- 2Check that the tone ring is securely fitted and free from scratches and deformation
- 3Check the connectors at the brake control module and the wheel sensor for contact resistance and oxidation, and make sure the wiring is not close to sources of interference
- 4Clear the code and road test to see whether it returns
- 5The brake system is safety critical: do not replace the brake control module because of this code; have a workshop repair the sensor or tone ring
Symptome, die Sie bemerken können4
- ABS warning lamp on
- General warning lamp on
- ABS, traction control and anti-skid function do not work
- With an intermittent fault the ABS lamp may only go out some way into the next drive
Was der Fehler beeinflussen kann3
- ABS is disabled
- Traction control, stability control, active yaw control (AYC) and brake assist are disabled
- Electronic brake force distribution (EBD) is disabled if two or more wheel sensors have failed
