Co oznacza ten kod błędu?
The alternator control module (ACM) reports to the engine control module when it detects an electrical fault in the generator, and the code is then stored. Worn carbon brushes or slip rings may be the cause. The code can also have been stored after a charger with excessive charge voltage was connected.
Możliwe przyczyny
- A charger delivering excessive charge voltage was connected earlier
- Worn carbon brushes in the generator
- Damaged alternator control module (ACM, charge regulator)
- Damaged generator
Co możesz zrobić
- 1If you have a diagnostic tool, read the battery voltage and the target value for the generator charge voltage with the engine running
- 2Switch on some high-current loads, such as the blower fan and high beam, and see whether the battery and charging cope
- 3If the battery and charging cannot cope, the fault is probably permanent; if they can, the fault may have been intermittent
- 4Have a workshop check the generator carbon brushes and slip rings; if they are worn, the control module or the generator must be replaced
- 5Ask yourself whether a battery charger has been connected to the battery before; a charger with too high charge voltage can cause this code
Objawy, które możesz zauważyć5
- The "Generator not charging" warning lamp lights with the engine running
- The battery discharges
- The starter motor turns the engine slowly
- The electrolyte in the battery boils with the engine running
- The headlamp bulb blows
