Normal Operation

WARNING: This page is about a different car, the 2005 Mercury Mountaineer and 2005 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.

Under normal operation, the DATC module receives a ground through circuit 1203 (BK/LB). The DATC module is supplied constant battery voltage through circuit 729 (RD/WH) and ignition switched voltage through circuit 1050 (LG/VT).
