Was bedeutet der Fehlercode?
The signal from the blower fan control is faulty. This is probably caused by a defective or short-circuited potentiometer in the control. The control module then works from a midpoint value, so the fan may run at the wrong speed.
Mögliche Ursachen
- Defective potentiometer
- Potentiometer shorted to live voltage or ground
Was Sie tun können
- 1Check that the fan control 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 CCM unit 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
Symptome, die Sie bemerken können1
- Buttons and control knobs on the centre console (climate) do not work, work reduced or work incorrectly
Was der Fehler beeinflussen kann1
- The control module uses a value equal to half of the fan control's maximum travel
