Co oznacza ten kod błędu?

The fault is stored when the engine control module (ECM) finds that the system voltage is unstable while the engine is running. The causes are most often the connections to the battery and the system relay, or the earth connection to the battery. The charging system and the battery can also be the cause.

Możliwe przyczyny

Loose earth connection to the battery
Contact resistance in the connections to the system relay
Contact resistance in the connections to the battery
Damaged power supply or charging system
Damaged battery

Co możesz zrobić

1Check that the battery terminals and cable lugs are tight and free of oxidation
2Check the earth connection to the battery for looseness and oxidation
3Check the contact block of the system relay for contact resistance and oxidation
4If a generator fault code is stored, troubleshoot that code first
5If you have diagnostic equipment: read the system voltage in live data with the engine running and check whether the value changes erratically
6If the connections are clean and tight, have a workshop check the battery and charging system with diagnostic equipment
