Was bedeutet der Fehlercode?
The control module on the extended CAN network has received or sent faulty messages and has shut off its own communication, which is called bus-off. The cause is a break in one or both CAN wires in part of the network. The control module can then no longer talk to the rest of the car, and functions such as the park assist camera and cross traffic alert stop working.
Mögliche Ursachen
- Broken wiring: one or both CAN wires are open in part of the extended network
Was Sie tun können
- 1Read and note the fault codes in the modules you can reach, clear them and road test the car to see if the code returns
- 2Switch the ignition off and check the CAN wires for breaks, chafing and loose connectors, especially where wires branch
- 3With the battery negative lead disconnected, use a multimeter to confirm the wires are unbroken to the next connector. Wiggle plugs
- 4If the code returns, have a workshop with diagnostic equipment check the network. Replace the CEM only if testing shows it is faulty
