Was bedeutet der Fehlercode?
The humidity sensor sends an error message to the climate control module (CCM), which registers the fault. The cause is an internal fault in the sensor. Defogging of the windows and mirrors may then work poorly or stop.
Mögliche Ursachen
- Internal fault in the air humidity sensor
Was Sie tun können
- 1Clear the code and road test the car to see whether it returns
- 2Try the defog function with the control and see whether air reaches the windows
- 3Check that the humidity sensor connector is secure and not corroded
- 4With a diagnostic tool, read the humidity sensor value in live data while the defog runs; replace the sensor if it does not change
Symptome, die Sie bemerken können4
- Mist on the windows and/or the outside mirrors
- Mirror defog or defrost does not work
- Side window defog or defrost does not work
- Windscreen defog or defrost does not work
