Diagnostic trouble code (DTC) information CCM-0006

Condition

Courtesy of VOLVO CARS OF NORTH AMERICA.

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 diagnosed in ignition positions I and II.

The diagnostic trouble code (DTC) can only be diagnosed for the electronic climate control module (CCM) (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.
