Component Description

WARNING: This page is about a different car, the 2015 Ford C-Max. However, it is still accessible from the selected car via links, so may be relevant.

Steering Wheel Switches

The cruise control steering wheel mounted switches are momentary contact switches. Each steering wheel switch function corresponds to a specific resistance value. The SASM sends out a 5-volt reference voltage to the steering wheel switch and monitors the voltage when a switch is pressed. The voltage varies depending upon the resistance of the specific switch pressed, indicating which switch is pressed.

Brake Switch

When the brake pedal is applied, an electrical signal from the stoplamp circuit to the PCM deactivates the system. Under increased brake pedal effort, the cruise control deactivator switch opens and removes the ground signal from the PCM input circuit releasing the throttle, immediately deactivating the system.
