Was bedeutet der Fehlercode?

The engine control module checks the battery voltage once the engine has been running for a short while and the engine speed is above a set level. If the voltage is too low or too high, it treats this as a fault and the code is stored. The code concerns the battery voltage and charging itself, not a sensor.

Mögliche Ursachen

Defective charging system
Defective battery
Open circuit in the voltage supply wire

Was Sie tun können

1With a multimeter, check that battery voltage is normal while the engine runs, and that it does not become too high or too low as the engine speed rises
2Check that the battery terminals and cables are fully seated and free from oxidation
3If a battery charger or starter unit has been connected, check that the correct voltage was set; charging at too high a voltage can cause this code
4If the voltage is wrong, have a workshop check the charging system with suitable equipment
