    Hva betyr feilkoden?

    The engine control module has registered a communication failure with the CEM over the CAN network. It may be caused by a CAN communication problem, such as an open circuit in the wiring, or by an internal fault in the CEM, which may be damaged. Switching over to gas power is then not possible.

    Mulige årsaker

    • Open circuit in the CAN wiring
    • Damaged central electronic module (CEM)

    Hva du kan gjøre

    1. 1Read the fault codes in the central electronic module (CEM) and deal with them first, since they may be the cause
    2. 2Check the connectors and wiring of the CAN network between the engine control module and the CEM for open circuits and chafing
    3. 3Disconnect the battery negative lead and use a multimeter to check that the CAN wires have no open circuit or short to ground or supply voltage
    4. 4If the fault remains and no wires are damaged, the CEM may be damaged and need replacing; leave this to a workshop

    Symptomer du kan merke1

    • Switching over to gas power is not possible

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