Hva betyr feilkoden?
The BCM runs an internal self-check on its own components. The code is set when that check has registered an internal memory fault. The fault can only be detected once the test has started, and it requires the module to be replaced.
Mulige årsaker
- Internal fault in the brake control module
Hva du kan gjøre
- 1Replace the brake control module, as the fault lies inside it
- 2After replacement, the accelerometer (IMU) and the internal sensors of the brake module must be calibrated by a workshop
- 3Switch the ignition on and choose to continue the calibration when the system asks
- 4The brake system is safety-critical, so have a workshop carry out the replacement and the calibration
Symptomer du kan merke5
