Hva betyr feilkoden?
The brake control module (BCM) receives a global time signal from the central electronic module (CEM) on the CAN network, and when the quality of that signal is too low it is treated as a fault. The code is set at ignition on, and then hill start assist may not work. The fault most often lies in the wiring or in the CEM.
Mulige årsaker
- Open circuit in one of the CAN wires
- Short circuit between the CAN wires
- Defect inside the CEM
- Internal fault in another module on the same section of the CAN network
Hva du kan gjøre
- 1Read codes in the central electronic module and other affected modules, and correct them first
- 2Have a workshop measure the resistance in the CAN wires against ground and supply voltage and look for shorts and breaks
- 3Check that the wiring is not routed close to sources of interference, such as mobile phones
- 4Clear the code only once the cause has been corrected, and check that it does not return
- 5The brake system is safety-critical, so have a workshop carry out any work on the network and the modules
