Was bedeutet der Fehlercode?
The generator control module (ACM) has told the CEM about a mechanical fault inside the generator. The fault may be in the drive belt or belt tensioner, in the freewheel, or in the generator itself. The battery may discharge and the starter motor may turn slowly.
Mögliche Ursachen
- A damaged auxiliary drive belt and belt tensioner
- A damaged freewheel
- A damaged generator
Was Sie tun können
- 1Check that the drive belt is intact, not oily and not worn. Replace a damaged belt
- 2Check that the belt runs in line with the pulleys and that the tensioner keeps it tight
- 3Listen for unusual noise from the generator or belt with the engine idling
- 4Listen for unusual noise on start-up and when the engine slows. If it persists, replace the generator if you can, otherwise have a workshop do it
- 5After the work, clear the code and check that charging is normal and no noise is heard
Symptome, die Sie bemerken können5
- The charging warning lamp lights with the engine running
- The battery discharges
- The starter motor turns slowly
- Noise from the generator or the drive belt
- The engine judders under acceleration
