Hva betyr feilkoden?
The climate control module (CCM) monitors a signal from the blower fan motor and has registered that it is too high. This can mean the fan is blocked, or that the signal is faulty somewhere on the way between the fan motor and the control module. While the fault remains the fan will not start, and the cooling from the A/C system is lost.
Mulige årsaker
- Blocked blower fan motor
- Open circuit in the signal wire or the ground wire to the fan motor
- Control signal wire shorted to ground or battery voltage
- Diagnostic signal wire shorted to battery voltage
- Defective blower fan motor or power unit
- Contact resistance
Hva du kan gjøre
- 1With the ignition on, turn the fan control to highest, then lowest speed, and check the fan runs smoothly. If the battery was disconnected, a workshop may need to recalibrate it
- 2Check that the connectors at the fan motor and the climate control module are firmly seated. If any is loose, push it fully home and see whether the fan works
- 3Check that nothing is blocking the fan wheel in the climate system and that it turns freely by hand
- 4Check the fuses and the earth points to the fan motor, and use a multimeter to confirm that the ground wire is intact and has contact with ground (the body)
- 5Check that the signal and control wires have no chafing or broken insulation
- 6If the fault remains after these checks, have a workshop check the fan motor and power unit
