Hva betyr feilkoden?
Although the code is named after the anti-lock brake system control module, the signal concerns the brake control module (BCM), which sends information about the braking system to the four-wheel drive. The code is set when the DEM is told that the information from the BCM is incorrect. It is an event-controlled code, meaning information rather than a fault in the DEM, and the fault should be traced in the brake control module.
Mulige årsaker
- Fault in the brake control module (BCM), which sends out incorrect information
Hva du kan gjøre
- 1Read off the fault codes in the brake control module first and remedy them. The code is a follow-on fault and can be cleared once the root fault has been remedied
- 2Check that the fuses are intact; their locations are in the owner's manual or on the fuse box cover
- 3If you have a diagnostic tool, read the wheel speeds in live data during a test drive and check that they follow each other at steady speed
- 4The braking system is safety-critical: if the brakes feel different or the fault remains, have a workshop check the brake control module
Symptomer du kan merke1
- Four-wheel drive does not work
Hva feilen kan påvirke1
- Four-wheel drive has reduced function
