Normal Operation

WARNING: This page is about a different car, the 2006 Mercury Milan, 2006 Lincoln Zephyr, and 2006 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

Under normal operation, the electronic automatic temperature control (EATC) or dual automatic temperature control (DATC) module receives a ground through circuit GD116 (BK/VT). The DATC/EATC module is supplied constant battery voltage through circuit SBP07 (WH/RD) and ignition switched voltage through circuit CBP20 (YE/VT).
