The diagnostic trouble code (DTC) is stored if the climate control module (CCM) detects an open-circuit in the communication between the air quality sensor (AQS) and the climate control module (CCM) 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.

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

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]

Poor air quality in the passenger compartment.
