Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information CCM-0005

Condition




The diagnostic trouble code (DTC) is stored if the climate control module (CCM) detects a short-circuit to ground in the signal between the climate control module (CCM) and the passenger compartment temperature sensor.
The climate control module (CCM) uses the signal to control the passenger compartment temperature.
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
- The control module adopts a substitute value corresponding to 25 °C
- The normal value is the passenger compartment temperature.

Possible source
- There is a short-circuit to ground in the signal between the passenger compartment temperature sensor and the climate control module (CCM)
- The passenger compartment temperature sensor is not functioning.

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