Hva betyr feilkoden?

On request from the central electronic module (CEM) over CAN, the ECM controls the alternator's charge voltage via LIN. The code is set when there is a disturbance in communication with the alternator control module (ACM). The ACM then charges at a fixed voltage instead of regulating the charge.

Mulige årsaker

Internal fault in another control module on the same part of the LIN network
Damaged alternator control module (ACM), which is the charge regulator

Hva du kan gjøre

1Check the battery and its connections, since the fault shows up as a dead or weak battery.
2Look for loose, chafed or corroded connectors at the alternator and on the wiring to it.
3Have a workshop read out the fault codes and troubleshoot the alternator control module and LIN communication with diagnostic equipment, as this requires measurement.

Symptomer du kan merke2

Dead battery
Low battery or weak electrical power

Hva feilen kan påvirke1

The alternator control module (ACM) charges at a fixed voltage

Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
