Control System Logic

The controls for the climate control system are in one or more locations depending on vehicle option content:

The customer inputs are directly inputted in to the Dual Automatic Temperature Control (DATC) module.

When A/C  is selected, the HVAC  control module sends the request to the BCM  over the Medium Speed Controller Area Network (MS-CAN). The BCM  then sends the request to the PCM  over the High Speed Controller Area Network (HS-CAN).

On vehicles with Sony Sound the touch screen and voice commands can be used for climate control inputs.
