ATC Module
The automatic temperature control (ATC) module is mounted on the outboard end of the air inlet duct, behind the front passenger side of the instrument panel. The automatic temperature control (ATC) module processes inputs from the TSD, the switches on the integrated control panel and the system sensors. In response to these inputs, the automatic temperature control (ATC) module outputs control signals to the air conditioning (A/C) system and the heating and ventilation system.
Two electrical connectors provide the interface between the automatic temperature control (ATC) module and the vehicle wiring. The automatic temperature control (ATC) module uses hardwired inputs from the system sensors, the local interconnect network (LIN) bus to communicate with the stepper motors and the medium speed controller area network (CAN) bus to communicate with other control modules on the vehicle.
