Hva betyr feilkoden?
The signal from the blower fan knob is faulty. This is probably caused by a defective potentiometer, or by a short to supply voltage or ground in it. The control module then works from a midpoint value, so the fan may run at the wrong speed.
Mulige årsaker
- Defective potentiometer
- Potentiometer shorted to live voltage or ground
Hva du kan gjøre
- 1Check that the fan knob works by changing the speed of the cabin fan
- 2If the fault returns, have a workshop check the control and its connector
- 3If the fault is permanent the climate control module must be replaced, since the potentiometer cannot be replaced separately. Have a workshop do this
- 4If you have a diagnostic tool, activate the fan from the activation function and listen for it to start
Symptomer du kan merke2
- The blower fan runs at just one setting
- Buttons and control knobs on the centre console (climate) do not work, work reduced or work incorrectly
Hva feilen kan påvirke1
- The control module uses a value equal to half of the fan knob's maximum travel
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
