Hva betyr feilkoden?
The heater control module has found an electrical fault on the combustion air fan motor, for example a short to battery voltage or an open circuit. The heater's function is blocked, and the heating in the cabin can be poor. The fault may be caused by a loose connector, damaged wiring or a damaged fan motor.
Mulige årsaker
- Contact resistance, oxidation or open circuit in the connections
- Open circuit in the wiring
- Wiring short-circuited to battery voltage
- Damaged fan motor
Hva du kan gjøre
- 1Check that the fuse for the auxiliary heater is intact.
- 2With the ignition off, check the connectors and wiring to the fan for corrosion, looseness and damage.
- 3Use a multimeter to check that the wiring to the fan is not broken and has no battery voltage when the ignition is off.
- 4If you have a diagnostic tool: activate the heater fan and listen for a buzzing sound. If nothing is heard, the fault is probably still present.
- 5Replace the fan motor if it is damaged, but only after the wiring has been checked and found to be in order.
- 6If the fault remains after these checks, have a workshop with diagnostic equipment investigate further.
