Hva betyr feilkoden?
On the V60, the brake control module (BCM) has detected a short to ground in the circuit to the pedal position sensor in the brake booster. The sensor tells the module how quickly the brake pedal is pressed, and brake assistance needs it to help during an emergency stop.
Mulige årsaker
- Wires shorted to ground
- Break in the wires
- Damaged pedal position sensor
Hva du kan gjøre

- 3Check the connector at the pedal position sensor and the wiring for chafing and damage, especially where the cable could short to ground
- 4Check the wiring with diagnostic equipment and replace the pedal position sensor if it is damaged
- 5The braking system is safety critical: do not work on the pedal position sensor or brake booster yourself; leave this to a workshop, and drive carefully until the fault is fixed
