Automatic Temperature Control (ATC) Module

CIRCUIT OPERATION
Circuit F71 supplies battery voltage to the Automatic Temperature Control (ATC) module when the ignition switch is in the RUN position. Circuit F60 from fuse 20 in the junction block connects to the ATC module. Circuit F60 is HOT at all times. Circuit Z4 provides ground for the ATC module.

Circuit E2 from the headlamp dimmer switch connects to the ATC module.

The ATC module communicates with other vehicle modules and controllers on the CCD bus. Circuits D1 and D2 for the CCD Bus connect to the ATC module.
