Normal Operation

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

The parking aid system is enabled when the vehicle ignition is in RUN and the transmission is in REVERSE. The system can be disabled by the parking aid disable switch. The parking aid module sends a signal to the LED over circuit 1436 (VT/OG) when the switch is pressed. The switch is grounded through circuit 57 (BK).
