Co oznacza ten kod błędu?
Brake pressure sensor A needs calibrating, but the calibration has not been carried out or has been done incorrectly. The brake control module (BCM) therefore cannot rely on the pressure signal, and the stability functions may be affected until calibration is done.
Możliwe przyczyny
- The calibration has failed
- The calibration has not been carried out
- Internal fault in the brake control module
Co możesz zrobić
- 1Have a workshop carry out the calibration of the brake pressure sensor with diagnostic equipment
- 2If the code does not return after calibration, no further action is needed. Drive the car for a while and read the code to check
- 3If the code returns after calibration, the brake control module normally needs replacing by a workshop
- 4The braking system is safety critical: do not carry out the calibration yourself; leave this to a workshop, and drive carefully until the fault is fixed
Objawy, które możesz zauważyć3
- Anti-spin and anti-skid indication shows a fault or no indication
- Anti-spin function does not work
- Stability function does not work
Na co może wpływać usterka2
- Traction control, stability control and brake assistance can be disabled
- Active yaw control (AYC) is blocked
