Was bedeutet der Fehlercode?

The brake control module (BCM) has not received the signal from the central electronic module (CEM) that contains the vehicle model information. The code is set when the signal is missing after the ignition is switched on, and most often means a module from another vehicle model has been fitted. The code only applies to cars with DSTC.

Mögliche Ursachen

A brake control module from another vehicle model has been fitted
A central electronic module from another vehicle model has been fitted

Was Sie tun können

1Read codes in the central electronic module and troubleshoot them first
2Check that the correct brake control module and central electronic module for this vehicle model are fitted
3Check the CAN wiring between the brake control module and the central electronic module for breaks, shorts to ground and shorts to supply voltage
4Check the connectors on the two modules for contact resistance and oxidation
5The brake and stability systems are safety-critical, so have a workshop carry out any work on the modules
