Hva betyr feilkoden?
The engine control module cannot communicate with the central electronic module (CEM), which holds the vehicle immobilizer code. During start-up, the key is verified and the immobilizer codes held in the engine control module and the CEM are compared, and without that link starting can become difficult.
Mulige årsaker
- Open circuit on one of the CAN cables
- Short circuit between the CAN cables
- Damaged engine control module
Hva du kan gjøre
- 1Read out the fault codes in the CEM and in the engine control module, and fix the CAN codes first
- 2Check the battery charge and that the fuses are intact
- 3Check the connectors at the engine control module and the CEM for play and corrosion
- 4Look for breaks and chafing on the CAN cables between the engine control module and the CEM
- 5Erase the fault code only when the CEM faults are fixed, then try several starts to check
- 6If the engine control module is suspected to be faulty, have a workshop check and replace it. Programming control modules is workshop work
Symptomer du kan merke2
- The engine is hard to start
- The starter motor cranks slowly, and the problem can occur at any time or only at some starts
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
