    Hva betyr feilkoden?

    The ECM monitors the feed through the system relay and has logged a voltage that is too high. The cause is a faulty charging system. The engine may then be hard to start or fail to start at all. The fault applies to the C30, C70 (06-), S40 (04-), S60 (-09), S80 (-06), V50, V70 (00-08), V70 XC and XC90.

    Mulige årsaker

    • Faulty charging system

    Hva du kan gjøre

    1. 1If you have a diagnostic tool: read the battery voltage with the engine running and compare it with the generator's charging voltage
    2. 2Check that the battery connections are tight and clean
    3. 3Switch on a few high-current consumers, such as the blower or high beam, and see how the voltage behaves
    4. 4If the code was stored after a battery charger was connected, check that the charger did not give too high a charging voltage
    5. 5If the fault remains, have a workshop check the generator's charging function and its control module

    Symptomer du kan merke1

    • The engine does not start, sometimes or all the time

    Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
