ATC Module: Notes

The ATC module is mounted on the outboard end of the air inlet duct, behind the front passenger side of the instrument panel.

The ATC module processes inputs from the center instrument panel switch pack, system sensors and the medium speed CAN (controller area network) bus, then outputs the appropriate control signals to the A/C system and the heating and ventilation system. In addition to controlling the A/C system and the heating and ventilation system, the ATC module also controls the following:
