Diagnostic trouble code (DTC) information CCM-0063

Condition 

The diagnostic trouble code (DTC) is stored if the climate control module (CCM) detects a fault in the damper motor module (DMM) temperature right.

The climate control module (CCM) communicates with the damper motor module (DMM) temperature right via LIN bus 2.

The damper motor module (DMM) transmits information to the climate control module (CCM) about status.

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 

• Internal fault in the damper motor module (DMM) for temperature right
• Incorrect calibration due to loss of power.

Fault symptom[s] 

• The passenger compartment temperature does not correspond to the set position.
• Air flow problem.
