What does this fault code mean?
The ECM receives cruise control information over CAN from several control modules. The code is set when a CAN message about the cruise control from the front monitoring module (FSM) or the central electronics module (CEM) is faulty. It is checked while driving with the cruise control activated.
Possible causes
- Contact resistance or oxidation in the connector blades
- Fault in the CAN network
What you can do
- 1Check that the fuses are intact
- 2If you have diagnostic equipment: read the fault status during a safe test drive with the cruise control switched on and see whether the fault is active
- 3Check the connectors in the cruise control circuit for contact resistance and oxidation
- 4Clear the code and road test the car with the cruise control switched on, to see whether it returns
- 5If the fault remains, have a workshop check the CAN network
Symptoms you may notice1
- No noticeable symptoms for the driver
General guidance for car owners. Diagnosis on the car can point to a different cause.
