Hva betyr feilkoden?
Although the code is titled signal missing, it is set by a message from the CEM that the ECM gets over CAN. The message concerns the analog accelerator pedal sensor signal or a CAN communication fault.
Mulige årsaker
- The cause is sought in the central electronic module (CEM)
Hva du kan gjøre
- 1Start with the CEM fault codes, deal with them, and only then clear this code
- 2If you have a diagnostic tool: check that the accelerator pedal value changes in live data when the pedal is moved, with the engine running
- 3If no fault is found in the CEM, have a workshop with diagnostic equipment fault-trace the CAN communication
- 4The accelerator pedal may be out of action when the brake is pressed. Do not drive with a fault in throttle response, and have a workshop check it at once
Symptomer du kan merke2
- Cruise control does not function at all
- Poor accelerator pedal response
Hva feilen kan påvirke1
- The accelerator pedal is out of action when the brake is pressed
