Hva betyr feilkoden?
The brake control module has registered an internal electrical fault in the part that drives the valve coil for control channel B, valve 1, in the hydraulic unit. The fault lies in the module and affects ABS, stability and traction control.
Mulige årsaker
- Fault inside the brake control module (BCM)
Hva du kan gjøre
- 1Activate the hydraulic unit valves with diagnostic equipment; if no ticking sound is heard, the module has an internal fault
- 2Clear the code and road test; if it returns, a workshop should replace the brake control module
- 3After replacing the brake control module, programming and calibration are needed, as a new unit is supplied without software
- 4The brake system is safety critical: do not work on the brake control module yourself, and drive carefully until the fault is fixed
Symptomer du kan merke5
- Anti-spin function does not work
- Anti-skid does not work
- Adaptive cruise control and forward monitoring do not work

Hva feilen kan påvirke3
- Anti-lock braking (ABS), traction control and stability control are disabled
- Dynamic stability control (AYC) is disabled
- Electronic brake force distribution (EBD) and brake assist are disabled
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
