System
Climate Control Module (CCM)
Volvo models this fault code applies to
Applies to the following models:
7 modelsS60 (2011–), S80 (2007–), V60 (2011–), V60 Cross Country (2015–), V70 (2008–), XC60 (2009–), XC70 (2008–)
What does this fault code mean?
The climate control module (CCM) checks the air quality sensor (AQS) and has registered a signal that points to an open circuit or a short to battery voltage. The sensor therefore gives the control module no usable signal. The fault shows up as poor air quality in the cabin.
Possible causes
- Open circuit or short to battery voltage
What you can do
- 1Check that the fuses are intact, for example the fuse for the climate control module
- 2Road test the car and check the affected functions to see whether the fault is still present
- 3After these checks, read off and clear the fault code and see whether it returns
- 4Use a multimeter to check that the wire to the air quality sensor has no contact with the battery supply and that it is not broken
- 5If the wire is intact but the fault remains, replace the air quality sensor
Symptoms you may notice1
- Poor air quality in the cabin
