Co oznacza ten kod błędu?
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.
Możliwe przyczyny
- 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
Co możesz zrobić
