Co oznacza ten kod błędu?
The engine control module (ECM) takes in the desired charge voltage from the central electronic module (CEM) and controls the alternator through the alternator control module (ACM) using LIN communication. The ECM also checks that communication with the ACM is working. The code is set when communication with the ACM is lost, and
Możliwe przyczyny
- Contact resistance and oxidation in connections
- Short circuit between the LIN wires
- Open circuit in one of the LIN wires
- Internal fault in another control module on the same part of the LIN network
- Damaged alternator control module (ACM), the charge regulator
- Fitting an alternator whose charge regulator is not designed for LIN can also set this code
Co możesz zrobić
- 1Check that the fuses are intact and that the battery terminals and earth connections are secure
- 2Check the connector at the alternator control module for contact resistance and oxidation
- 3With a multimeter you can check that the signal cable between the control modules has no open circuit and no short to ground or voltage
- 4Use a multimeter to check that the engine and the body have the same potential at the earth points between them
- 5If the fault remains, have a workshop check the alternator control module and the LIN communication
Objawy, które możesz zauważyć4
- Battery is dead or has too low a voltage
- Charge warning lamp lights or behaves abnormally
- Red warning symbol and text message shown in the driver information display
- Engine is hard to start or does not start
Na co może wpływać usterka1
- The charge regulator charges at a fixed voltage
