What does this fault code mean?
The climate control module (CCM) has not been calibrated after a repair, a software update or the replacement of a component. Without calibration, frozen values may show incorrect readings. The fault means the calibration is not complete, not necessarily that a component is broken.
Possible causes
- Calibration not performed
What you can do
- 1After replacing a damper motor, it must be identified before calibration, so have a workshop do that
- 2Have a workshop carry out the calibration with diagnostic equipment, with the car at normal room temperature
- 3Clear the code and road test the car to see whether it returns
- 4Check that the temperature and air distribution controls respond as expected
- 5If the code returns after calibration, fault-trace the code that is shown
Symptoms you may notice5
- Airflow does not work as it should
- Temperature control is uneven
- Front seat heating does not operate
- Temperature control or air conditioning does not work
- Rear seat does not heat, or gets too hot
General guidance for car owners. Diagnosis on the car can point to a different cause.
