Was bedeutet der Fehlercode?

The fault code is labelled bus off, but it concerns an open circuit in the circuit to mode indicator 1 in the Four-C switch. The driving-mode indication then fails to appear, and Four-C cannot be shown correctly on the switch.

Mögliche Ursachen

Poor contact from oxidation or contact resistance in the connectors
Open circuit in the power supply wire to the mode indicator
Open circuit in the ground wire to the Four-C switch
The Four-C function switch is damaged

Was Sie tun können

1Check the connector at the Four-C switch for looseness or oxidation
2Use a multimeter to check that the wires to the mode indicator and the ground wire are not broken, with the ignition switched off
3Try the switch and see whether the driving-mode indication returns after the test drive
4If the wires are sound: have a workshop check the switch and replace it if needed

Symptome, die Sie bemerken können1
