Co oznacza ten kod błędu?
The generator's control module (ACM) reports an electrical fault in the generator to the engine control module, and that is what sets the code. It may be caused by worn brushes, a damaged generator control module or a damaged generator, or by a battery charger with too high a charge voltage having been connected. The fault applies to the C30, C70 (06-), S40 (04-) and V50.
Możliwe przyczyny
- A battery charger with too high a charge voltage was connected earlier
- Worn brushes (carbon)
- Damaged generator control module (charge regulator)
- Damaged generator
Co możesz zrobić
- 1Read and note the code, clear it and road test to see whether it returns
- 2Start the engine and read the battery voltage, if you have a diagnostic tool
- 3Switch on a few high-current consumers and see whether the battery voltage stays steady
- 4Listen for unusual noise from the generator and check whether the generator not charging lamp comes on while the engine runs
- 5Have a workshop replace the generator or its control module if the brushes or slip rings are worn or if the fault remains
Objawy, które możesz zauważyć5
- The generator warning lamp (not charging) comes on while the engine runs
- The battery discharges
- Low rotation speed in the starter motor
- The electrolyte in the battery boils when the engine runs
- The headlamp bulb blows
