Was bedeutet der Fehlercode?
The brake control module (BCM) has registered that the speed signal is too high and sends a fault message to the engine control module, which then sets the code. The code therefore shows that the signal from the brake control module is faulty, and the fault most likely sits in a module other than the engine control module.
Mögliche Ursachen
- The brake control module receives a faulty speed signal
Was Sie tun können
- 1Fault-trace from the module that sends the signal, which is the brake control module (BCM); the engine control module only reports the fault
- 2Read the fault codes in the brake control module and deal with them first; this code cannot be cleared until the root fault is remedied and its code cleared
- 3Check the connectors and wiring of the CAN network for open circuits, short circuits and chafing
- 4The brake control module is safety-critical, so do not work on it yourself; have a workshop check it
Symptome, die Sie bemerken können1
- Malfunction indicator lamp (MIL) is on
Was der Fehler beeinflussen kann1
- The brake control module's speed signal is replaced by a fixed value
