Was bedeutet der Fehlercode?

The code says that the signal between control modules is missing. The engine control module has registered a serious disturbance on the high speed side of the CAN network, so communication is blocked and the module cannot be reached.

Mögliche Ursachen

Contact resistance or oxidation in the connections
Open circuit in one of the CAN wires
Short circuit between the CAN wires
Internal fault in the engine control module
Internal fault in some other control module on the same section of the CAN network

Was Sie tun können

1Start by reading the fault codes from the CEM and the other control modules. There is no specific fault-tracing procedure for this code
2Check that the fuses are intact and that the battery is connected
3Check the connectors in the CAN network at the engine control module and the CEM for corrosion and loose contacts
4Look for breaks and chafing on the CAN wires, especially where they bend or are pinched
5Erase the fault codes only after the other faults are fixed, then road test the car to see whether the fault returns
6If the fault remains, have a workshop check the CAN network with diagnostic equipment

Symptome, die Sie bemerken können2

A warning message or warning symbol appears in the display
The Check engine warning lamp lights up or behaves abnormally
