HVAC Module
The EATC system uses a remote HVAC module that is separate from the control interface. The Front Controls Interface Module (FCIM) provides the interface for the vehicle occupants to control the climate control system. When selections are made, the FCIM communicates the selections to the HVAC module through the Medium Speed Controller Area Network (MS-CAN), and the HVAC module adjusts the climate control system components to achieve the desired state. When the climate control system is operating in AUTO mode via command from the FCIM, the required climate control system settings are determined by the HVAC module. The HVAC module then adjusts the climate control system components to the desired state. The remote HVAC module is located under the driver side of the instrument panel.
