Was bedeutet der Fehlercode?
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.
Mögliche Ursachen
- Open circuit on one of the CAN cables
- Short circuit between the CAN cables
- Damaged engine control module
Was Sie tun können
- 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
Symptome, die Sie bemerken können2
- The engine is hard to start
- The starter motor cranks slowly, and the problem can occur at any time or only at some starts
