Hva betyr feilkoden?
Through LIN communication, the engine control module receives information from the alternator control module (ACM) that the voltage level is too low, and the code is stored while the engine is running. The cause may be a battery charger or starter unit with the wrong charge voltage, poor contact, worn carbon brushes in the generator, or a damaged control module or generator.
Mulige årsaker
- A charger or starter unit supplying the wrong charging voltage is connected
- Contact resistance or oxidation in the connectors
- Worn carbon brushes in the generator
- Damaged alternator control module (ACM)
- Damaged generator
Hva du kan gjøre
- 1Check the connectors and connections to the generator and its control module for contact resistance and oxidation; clean and remedy them if needed
- 2Make sure no charger or starter unit delivering the wrong charge voltage is hooked up to the battery
- 3Have a workshop check the generator carbon brushes, since they may be worn
- 4If you have a diagnostic tool, read the generator charging current with the engine running
- 5If the connectors and brushes are in order, have a workshop try a new control module for the generator
Symptomer du kan merke3
- Text message in the display
- The battery may be dead
- The battery has low voltage or low power
