Was bedeutet der Fehlercode?

The ECM receives the information about the cruise control buttons from the central electronics module (CEM) over CAN and checks that it is reasonable. Each message should carry a sequence number that counts up, and here the number does not match. The code is set when the information from the CEM is faulty or unreasonable.

Mögliche Ursachen

The fault may lie in the central electronics module (CEM)

1Check that the fuses are intact
2If you have diagnostic equipment: read the fault codes in the central electronics module (CEM) and deal with them first
3Test the cruise control buttons on the steering wheel and check that they spring back and do not stick
4Check that the connectors to the central electronics module (CEM) are firmly seated and not corroded
