Hva betyr feilkoden?
This fault only applies to cars with automatic engine start and stop. The CEM monitors the secondary battery voltage. If the voltage is too low or too high, the automatic start and stop function does not work.
Mulige årsaker
- Contact resistance or oxidation in the terminals
- Damaged fuse for the voltage supply
- Open circuit on the voltage supply from the secondary battery, or on its ground cable
- Poorly charged battery or corroded connecting cables
- Damaged battery
- A battery charger with the wrong voltage has been used
Hva du kan gjøre
- 1Check that the battery is charged and that the battery terminals are clean and tight
- 2Check the fuse for the voltage supply from the secondary battery
- 3Has a battery charger been used recently? Check that it is meant for this car
- 4Clear the code and road test the car to see whether it returns
- 5If the fault remains, have a workshop check the secondary battery
