Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information CCM-DD15

Condition




The diagnostic trouble code (DTC) is stored if the climate control module (CCM) detects an open-circuit in the communication between the climate control module (CCM) and the damper motor module (DMM) temperature left on LIN bus 1.
The diagnostic trouble code (DTC) can occur together with diagnostic trouble codes (DTCs) for other components on LIN bus 1 (CCM-DD10 - CCM-DD16) depending on where the open-circuit has occurred.
The diagnostic trouble code (DTC) can be diagnosed at ignition switch position II.

Substitute value
- None.

Possible source
- Open-circuit on LIN bus 1 between the climate control module (CCM) and the air quality sensor (AQS)
- Contact resistance, oxidation or loose connections in the connectors.

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