Was bedeutet der Fehlercode?
The climate control module (CCM) loses contact with the air quality sensor (AQS) on LIN bus 2, so the sensor cannot send its readings. Air quality in the cabin cannot then be monitored. The fault only applies to cars with electronic climate control (ECC).
Mögliche Ursachen
- Break in LIN bus 2 wiring between the module and the air quality sensor
- Poor contact, corrosion or loose connections at the connectors
Was Sie tun können
- 1Check that the air quality sensor connector is secure and clean
- 2Clear the codes, road test the car and see whether they return
- 3Check with a multimeter that the wire between the module and the sensor is not open when the connectors are disconnected
- 4Check with a multimeter that the sensor has voltage and ground at the connector when the ignition is on
- 5Replace the air quality sensor if you can reach it and the fault remains, otherwise have a workshop do it
Symptome, die Sie bemerken können1
- Poor air quality in the cabin
