Co oznacza ten kod błędu?
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.
Możliwe przyczyny
- Internal fault in another control module on the same part of the LIN network
- Damaged alternator control module (ACM), which is the charge regulator
Co możesz zrobić
- 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.
Objawy, które możesz zauważyć2
- Dead battery
- Low battery or weak electrical power
Na co może wpływać usterka1
- The alternator control module (ACM) charges at a fixed voltage
