Hva betyr feilkoden?
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.
Mulige årsaker
- 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
Hva du kan gjøre
- 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
