Normal Operation

WARNING: This page is about a different car, the 2006 Mercury Montego, 2006 Ford Freestyle, and 2006 Ford Five Hundred. However, it is still accessible from the selected car via links, so may be relevant.

The parking aid system is enabled when the ignition switch is in the RUN position and the transmission is in REVERSE. When the parking aid switch is pressed the parking aid module is momentarily grounded through circuit 1435 (DG/VT) and disables the parking aid system.
