Hva betyr feilkoden?
On the V60, the brake control module (BCM) receives speed information from four wheel sensors. The signal from the left rear wheel sensor is missing, or it shows too low a speed, so the module treats the signal as invalid. The speed data for that wheel is then missing for ABS and the stability functions.
Mulige årsaker
- Damaged wiring to the left rear wheel sensor
- Damaged left rear wheel sensor
Hva du kan gjøre
- 1Read and note the code, clear it and road test the car to see whether it returns
- 2Look for damage in the wiring to the left rear wheel sensor, particularly in the wheel arch
- 3Check that the left rear wheel sensor is undamaged and secure
- 4Read the wheel speed with diagnostic equipment and replace the wiring or sensor as needed
- 5The braking system is safety critical: do not work on the ABS system yourself; leave this to a workshop, and drive carefully until the fault is fixed
Symptomer du kan merke5
- ABS does not work or activates suddenly
- Anti-spin function does not work
