Hva betyr feilkoden?
The CEM has registered an open circuit or a short to ground in the S-supply from the ignition switch, and the fault is intermittent. This means it was present at an earlier time but is no longer there. The starter motor may then work at times and fail at others.
Mulige årsaker
- Contact resistance in the terminals
- Open circuit or short to ground in the S-supply
- The key is not recognised
- Defective ignition switch
Hva du kan gjøre
- 1Check that the connectors at the CEM and the ignition switch are secure and free from corrosion
- 2Lightly move the wiring at the connectors and see whether the fault returns
- 3Check with a multimeter that the wire reads battery-level voltage with the key in the ignition switch
- 4If the fault returns, have a workshop replace the ignition switch
