Was bedeutet der Fehlercode?
The code points to a probable overload in the coolant pump relay. The engine control module sets it when it judges that this is the case, and the coolant pump is then switched off. Causes can include loose or shorted connections, or a damaged pump or damaged wiring to the pump.
Mögliche Ursachen
- Loose connection or oxidation in the connector
- Short circuit on the connections
- Damaged coolant pump relay
- Damaged pump
- Short circuit or open circuit in the wiring to the pump
Was Sie tun können
- 1Check that the relevant fuses are intact and that the connectors at the coolant pump relay are fully seated
- 2With a multimeter, check that there is no short circuit in the connections to the relay and to the pump
- 3If the connectors and wiring are sound, the pump or relay may be damaged; have a workshop check and replace the faulty part
Symptome, die Sie bemerken können4
- Uneven temperature in the cabin
- HYBRID drive mode is used all the time or too often, with the combustion engine running
- The parking heater does not work
