Hva betyr feilkoden?
The engine control module communicates with the alternator control module (ACM) over the LIN bus. The fault code is set when the engine control module detects a fault in that communication. The alternator warning lamp can light with the engine running, and a message can appear in the display.
Mulige årsaker
- Faulty signal
- Contact resistance or oxidation in the connectors
- Damaged alternator control module (ACM)
- Signal missing
- Open circuit on the signal cable
Hva du kan gjøre
- 1Inspect the ACM connector for contact resistance and oxidation
- 2Check that the alternator is bolted down firmly so that it has a good earth connection
- 3Disconnect the connector at the engine control module and check the signal cable for breaks, for a short to ground and for a short to supply voltage
- 4If you have a diagnostic tool: start the engine and read the alternator charging current in live data. The value should be steady while the engine runs
- 5If the alternator has been replaced, check that it is designed for LIN communication
- 6If the fault remains after these checks, have a workshop check the alternator control module
Symptomer du kan merke2
- The Gen. not charging warning lamp lights with the engine running
- A message appears in the information display
