Normal Operation

WARNING: This page is about a different car, the 2007 Lincoln Mark LT and 2007 Ford Pickup. 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 (R). The system can be disabled by the parking aid 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).
