    Hva betyr feilkoden?

    The engine control module has registered a voltage from the system relay that is too low. The fault is caused by a faulty charging system or a damaged battery, and the engine may then stall 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
    • Damaged battery

    Hva du kan gjøre

    1. 1Check the battery voltage and condition
    2. 2Check the generator's charging function
    3. 3If you have a diagnostic tool: read the system relay voltage in live data with the engine running
    4. 4Check that the connectors at the engine control module and the system relay have no contact resistance or oxidation
    5. 5If the fault remains, have a workshop try a new system relay

    Symptomer du kan merke2

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

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