Hva betyr feilkoden?
The engine control module communicates with the generator's control module (ACM). The fault code is set when the generator's control module reports that the generator is too hot, or that there is a mechanical fault, for example the generator standing still while the engine is revving. The fault applies to the C30, C70 (06-), S40 (04-) and V50.
Mulige årsaker
- Defective auxiliaries belt or belt tensioner
- Damaged freewheel
- Damaged generator
- Air intake or air outlet to the generator is blocked
Hva du kan gjøre
- 1Check that the drive belt and the belt tensioner are not damaged
- 2Check that the air intake and air outlet to the generator are not blocked
- 3Check the generator freewheel: the rotor shaft should turn freely in one direction only
- 4If you have a diagnostic tool: read the generator temperature in live data, if available, and see whether it rises unreasonably
- 5If the code is set again after driving, have a workshop replace the generator
Symptomer du kan merke4
