Was bedeutet der Fehlercode?
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.
