What does this fault code mean?

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.

Possible causes

The calibration has failed
The calibration has not been carried out
Internal fault in the brake control module

What you can do

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

Symptoms you may notice3

Anti-spin and anti-skid indication shows a fault or no indication
Anti-spin function does not work
Stability function does not work

What the fault can affect2

Traction control, stability control and brake assistance can be disabled
Active yaw control (AYC) is blocked
