What does this fault code mean?
The brake control module (BCM) with its hydraulic unit is supplied calibrated from the factory. The code is set when the calibration for the analogue hydraulic valves is missing or when the calibration data does not match.
Possible causes
- Calibration of the brake control module is missing
- Internal fault in the brake control module
- Damaged brake control module
What you can do
- 1Read codes in the central electronic module first, as the fault may lie there
- 2Have a workshop download the software again following the workshop procedure, then check that the code is not set again
- 3If the fault returns, have a workshop replace the brake control module and calibrate it
- 4The brake system is safety-critical, so have a workshop carry out all programming and any replacement
Symptoms you may notice5
- ABS warning lamp lit
- General warning lamp on
- Stability function does not work
- Traction control does not work
- Anti-skid function does not work
What the fault can affect2
- Stability control and traction control are disabled
- Dynamic stability control (AYC) is disabled
General guidance for car owners. Diagnosis on the car can point to a different cause.
