Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information CCM-DD16

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) air distribution 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-DD12 - CCM-DD16) depending on where the open-circuit has occurred.
The diagnostic trouble code (DTC) can be detected at key position 1 or 2 (not key position 3).

Substitute value
- None.

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

Fault symptom[s]
- Misting on the windows and/or door mirrors.
- Air flow problem.
