Was bedeutet der Fehlercode?

The brake control module (BCM) compares the signal from the vacuum pressure sensor in the brake booster with the signal from the brake pressure sensor. When the vacuum signal does not match the brake pressure, the module judges it to be incorrect.

Mögliche Ursachen

Damaged vacuum pressure sensor
Internal fault in the brake control module

Was Sie tun können

1Read and note the code, clear it and road test the car to see whether it returns
2Start the engine and have a workshop read the vacuum pressures in the brake booster with diagnostic equipment while the brake pedal is pressed
3If the vacuum pressures do not agree, the vacuum sensor needs replacing by a workshop. If they agree, the fault may have been temporary
4The braking system is safety critical: do not work on the brake booster yourself; leave this to a workshop, and drive carefully until the fault is fixed
