Was bedeutet der Fehlercode?
The engine control module (ECM) communicates with the alternator control module (ACM) over LIN communication. The fault code is set when messages from the ACM are missing, or when the ECM otherwise detects a fault in the communication. The generator can then charge with a fixed voltage.
Mögliche Ursachen
- Open circuit on the signal wire or on one of the LIN wires
- Contact resistance or oxidation in the connections
- Short circuit between the LIN wires
- Internal fault in another control module on the same part of the LIN network
- Damaged alternator control module (ACM), meaning the charge regulator
- A generator with a charge regulator not designed for LIN communication is fitted
Was Sie tun können
- 1Check that the connectors to the charge regulator are firmly seated and free from oxide
- 2Use a multimeter to check that the signal wire between the control modules has no break and is not short-circuited to earth or battery positive
- 3Have a diagnostic tool: start the engine and follow the generator charging current in live data to see whether it changes as it should
- 4Check that the correct type of generator with charge regulator is fitted to the car
- 5If the fault code returns: have a workshop check the LIN communication and the charge regulator
Symptome, die Sie bemerken können5
- The battery may be dead or have low voltage
- The charge warning lamp lights or behaves abnormally
- The generator or charge regulator may cause power supply problems
- The engine is hard to start and cranks slowly during start attempts
- The engine hesitates during acceleration
Was der Fehler beeinflussen kann1
- The charge regulator charges with a fixed voltage
