Co oznacza ten kod błędu?
On the V60, the brake control module (BCM) has detected a short to supply voltage in the circuit to the ABS pump motor. The pump motor builds the brake pressure needed for ABS, stability control and brake assistance. The fault may lie in the wire, which has come into contact with the battery's positive supply, or in the pump motor itself.
Możliwe przyczyny
- Damaged pump motor
- Wire to the pump motor shorted to battery voltage, for example through chafing
- Internal fault in the brake control module
Co możesz zrobić
- 1Read and note the code, clear it and road test the car to see whether it returns
- 2Check the pump motor fuse in the engine bay relay and fuse box. If it has failed, the circuit should be checked before a new fuse is fitted
- 3Check that the wire to the pump motor is not chafed or pinched, especially where it could touch anything carrying live voltage
- 4With diagnostic equipment activate the pump motor and check that it starts and runs normally
- 5If the pump motor does not start, the hydraulic unit is probably damaged and needs replacing by a workshop
- 6Do not work on the brake hydraulic unit or pump motor yourself; leave this to a workshop. Drive carefully until the fault is fixed
Objawy, które możesz zauważyć5
- Front monitoring and City Safety do not work
- Cruise control will not engage
- ABS warning shows a fault or no indication
- Traction control and stability function do not work
- Brake pedal requires more force than normal
Na co może wpływać usterka2
- Active yaw control (AYC) is blocked
- ABS, traction control, stability control and brake assistance can be disabled
