Hva betyr feilkoden?
The engine control module drives the cooling fan with a PWM signal and monitors its control circuit. If the signal to the fan is faulty, or the control circuit gives faulty signals, the fault is set. It may be noticed as the engine overheating or the fan running all the time.
Mulige årsaker
- Poor contact, resistance or oxidation in the connections
- Open circuit in the power supply to the cooling fan
- Open circuit in the signal wire, or signal wire shorted to ground or voltage
- Damaged cooling fan
Hva du kan gjøre
- 1Check that the fuse for the cooling fan circuit is intact. Their locations are shown in the instruction manual or on the fuse box cover
- 2Look for fan blades blocked by debris or damage, as this can cause the fault
- 3Switch off the ignition and check the cooling fan connector for looseness, contact resistance and oxidation
- 4Check that the earth lead is firmly and cleanly fixed at its earth point
- 5Use a multimeter to check that the signal wire to the fan has no open circuit and is not shorted to ground or voltage
- 6If the fault remains, have a workshop with diagnostic equipment check the fan control and the fan
Symptomer du kan merke2
- The engine overheats or runs hot
- The cooling fan runs all the time
