Was bedeutet der Fehlercode?
On the V60, the brake control module (BCM) has detected a short to battery voltage in the circuit to the pedal position sensor in the brake booster. The sensor tells the module how the brake pedal moves, and brake assistance needs the signal during an emergency stop.
Mögliche Ursachen
- Wires shorted to battery voltage
- Wires shorted to ground
- Break in the wires
- Damaged pedal position sensor
Was Sie tun können
- 1Read and note the code, clear it and road test the car to see whether it returns
- 2Read the codes in the engine control module and the central electronic module, as the fault may be linked to the brake light circuit
- 3Check the connector at the pedal position sensor and the wiring for chafing and damage where it could touch a live supply
- 4Read the pedal position sensor signal with diagnostic equipment and replace the 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
Symptome, die Sie bemerken können1
- No noticeable symptoms for the driver
Was der Fehler beeinflussen kann1
