What does this fault code mean?
The internal software in the power steering control module does not match the car's configuration. The module does not receive the correct configuration ID from the CEM. The cause may be that the module is set up for another car, or a break in the CAN wiring between the module and the CEM.
Possible causes
- Configuration fault: the module does not suit this car, for example a used unit with other software or hardware
- Open circuit in the CAN wiring between the control module and the CEM
What you can do
- 1Check whether the control module is the original one for this particular car
- 2Read off and clear the fault code, test drive and see whether it returns
- 3Have a workshop measure the wiring between the control module and the CEM, since it needs readings at several points
- 4Have a workshop reprogram the control module with the correct software for the car
- 5Safety note: steering is safety-critical, so have a workshop carry out the checks and the programming
Symptoms you may notice1
- The power steering regulation does not work
What the fault can affect2
- The control module shuts itself off ("bus-off")
- The control module still answers diagnostic commands
General guidance for car owners. Diagnosis on the car can point to a different cause.
