Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information CCM-0009

Condition




The diagnostic trouble code (DTC) is stored if the climate control module (CCM) detects that the blower fan for the passenger compartment temperature sensor is blocked.
The function of the blower fan is to supply the passenger compartment temperature sensor with air from the passenger compartment. This prevents the sensor reading from being affected by heat from the surrounding electronics.
The diagnostic trouble code (DTC) can be detected at key positions 1 and 2 (not key position 3).
The diagnostic trouble code (DTC) can only be diagnosed for the electronic climate control module (CCM) for the electronic climate control (ECC).

Substitute value
- None.

Possible source
- The blower fan for the passenger compartment temperature sensor is blocked
- The blower fan for the passenger compartment temperature sensor is not functioning.

Fault symptom[s]
- The passenger compartment temperature does not correspond to the set position.
- Poor heating in the passenger compartment.
