Normal Operation
WARNING: This page is about a different car, the 2004 Mercury Monterey and 2004 Ford Freestar. However, it is still accessible from the selected car via links, so may be relevant.
When the speed control actuator no longer senses power on circuit 535 (LB/RD), the speed control actuator deactivates the speed control system. When the brake pedal is applied and the speed control deactivator switch opens, battery voltage is removed from circuit 535 (LB/RD) to the speed control actuator.
