Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information CCM-0006

Condition




The diagnostic trouble code (DTC) is stored if the climate control module (CCM) detects an open-circuit in the power supply cable to the blower fan for the passenger compartment temperature sensor, or an open-circuit in the ground lead from the blower fan to the control module.
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
- Open-circuit in the power supply cable between the climate control module (CCM) and the blower fan for the passenger compartment temperature sensor
- Open-circuit in the ground lead between the blower fan for the passenger compartment temperature sensor and the climate control module (CCM)
- Contact resistance, oxidation or loose connections in the connectors
- 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.
