Was bedeutet der Fehlercode?
The infotainment control module (ICM) has detected serious interference on the low-speed CAN network, so CAN communication is blocked. The cause may be a short or break in the CAN wiring, or an internal fault in a module. The affected module switches itself off until its power is cut.
Mögliche Ursachen
- Short circuit between the CAN wires
- Open circuit in one of the CAN wires
- Internal fault in the control module
- Internal fault in another control module on the same part of the CAN network
Was Sie tun können
- 1Check that the fuses are intact and that the battery is in good condition, since low voltage can cause communication faults
- 2With a diagnostic tool, read the fault codes in the central electronic module (CEM). It monitors the CAN wires and can flag a short to earth or supply
- 3Check that the connectors on the CAN network are firmly seated and free from oxidation, and look for chafed cables
- 4Disconnect the battery negative terminal for a while and reconnect it. Modules that have gone into limp-home mode then return to normal operation
- 5If the fault remains, a workshop should measure the CAN network and find the module sending faulty messages. That module must be replaced
Symptome, die Sie bemerken können2
- Steering wheel radio controls do not respond
- Steering wheel navigation controls do not respond
Was der Fehler beeinflussen kann2
- The control module switches itself off (bus-off)
- It stays off until the power supply is cut, and it tries to communicate again when power is restored
