Hva betyr feilkoden?
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.
Mulige årsaker
- Defective charging system
- Defective battery
- Open circuit in the voltage supply wire
Hva du kan gjøre
- 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
Symptomer du kan merke1
- The car cannot run on gas
Hva feilen kan påvirke1
- Gas operation is blocked
