Was bedeutet der Fehlercode?

The code concerns valve 1 in the cooling circuit for the drive components of the hybrid, which the engine control module (ECM) monitors continuously. If the valve does not work, cooling of the electric drive components may stop. The code is set when the signal wire to the valve is shorted to ground or has an open circuit.

Mögliche Ursachen

Mechanical fault on the valve
Electrical fault on the valve
Short circuit or open circuit in the wires to the valve

Was Sie tun können

1Check that the fuses are intact; their location is shown in the owner's manual
2Check the connectors to the valve for contact resistance and oxidation
3Use a multimeter to check that the wires to the valve have no break and no contact with ground (the body)
4With a diagnostic tool, activate the valve in the cooling circuit and listen or feel whether it moves
5Have a workshop check the valve if the fault remains, since a mechanical fault in the valve is a possible cause
