Co oznacza ten kod błędu?
The all-wheel drive control module (DEM) sends to the brake control module (BCM) when all-wheel drive is active. The BCM has registered that the speed difference between the front and rear wheels is too large, so the stability function may not be activated.
Możliwe przyczyny
- Internal fault in the all-wheel drive control module (DEM)
Co możesz zrobić
- 1Read codes in the central electronic module first and troubleshoot them
- 2Read codes in the all-wheel drive control module and troubleshoot them according to their information
- 3Do not replace the brake control module for this code, as the fault does not lie in it
- 4The brake and stability systems are safety-critical, so have a workshop carry out any work on the all-wheel drive system and the brake control module
