Hva betyr feilkoden?
The engine control module (ECM) requests a fan speed from the electric fan control module, which varies the voltage to the fan motor steplessly. The code is set when the fan speed is too low. The fault may be an internal fault in the fan control module, a signal wire shorted to supply voltage or a damaged fan control module.
Mulige årsaker
- Internal fault in the electric fan control module
- The signal wire is short-circuited to supply voltage
- Damaged electric fan control module
Hva du kan gjøre
- 1Check that the fuses for the electric fan are intact. Their location is given in the owner's manual or on the fuse box cover
- 2Look for chafing or pinch damage on the signal wire to the electric fan control module, where it may have touched supply voltage
- 3Use a multimeter to check that the signal wire is not short-circuited to supply voltage
- 4If you have a diagnostic tool, read the fault status with the engine running and see whether the fault is still active
- 5If the fault remains, have a workshop check or replace the electric fan control module
- 6After repair, check that the fault status shows no fault once the diagnosis is complete
Symptomer du kan merke3
- The engine overheats or runs hot
- Temperature control or air conditioning does not work
- The temperature becomes uneven
