Was bedeutet der Fehlercode?

The engine control module checks the CAN communication with the electric power steering module (EPS). The fault code is set when communication with the EPS module is not working. The fault can come from the power supply, connections, wiring, or a module that does not suit this car.

Mögliche Ursachen

No power supply to the EPS module
Loose connection, contact resistance or oxidation in the connections
Open circuit in the wiring to the EPS module on the high speed side of the CAN network
Internal fault in another control module on the same network section
The EPS module does not belong to this car. A used unit with other software or hardware is one example

Was Sie tun können

1Read out the fault codes in the engine control module and the EPS module, and fix the CAN codes first
2Check that the fuses supplying the EPS module are intact
3Check the connectors at the EPS module and the engine control module for play and corrosion
4Look for chafing and breaks on the CAN wires running to the EPS module
5If the EPS module has been replaced, check that it is intended for this exact car
6Steering is safety-critical. If the steering feels unsafe, do not drive the car until a workshop has checked it

Symptome, die Sie bemerken können2

A text message and warning symbol appear in the display
Warning lamps and warning signals behave abnormally, for example the Check engine lamp
