Ford Mustang Service Manual: Pinpoint Tests
Principles of Operation
The speed control system is designed to maintain vehicle speed above 48 km/h (30 mph). After the ON switch is depressed, depressing the SET/ACCEL switch will activate the speed control servo. To increase a set speed, either depress and hold for continuous acceleration, or momentarily tap the SET/ACCEL switch for 1.6 km/h (1 mph) acceleration increments. To decrease a set speed, depress and hold the COAST switch until the target speed is reached, or momentarily tap the COAST switch for 1.6 km/h (1 mph) deceleration increments. When the speed control system has been disabled by tapping the brake pedal, the RESUME switch can be depressed and the vehicle will return to the original set speed if the vehicle is traveling over 48 km/h (30 mph) and the OFF switch has not been depressed.
NOTE: The deactivator switch is provided as an additional safety feature. Normally, when the brake pedal is depressed, an electrical signal from the brake lamp circuit to the speed control servo will deactivate the system. Under increased brake pedal effort, the deactivator switch will open and remove power to the speed control servo, releasing the throttle independent of the speed control servo.
NOTE: The air bag sliding contract provides the electrical interface between the steering column wiring and the speed control actuator switches in the steering wheel.
The inputs to the speed control servo are the:
- vehicle speed signal.
- speed control actuator switches.
- brake pedal position (BPP) switch.
- clutch pedal position (CPP) switch.
- deactivator switch.
The output of the speed control servo is the:
- speed control actuator cable controlling the throttle position.
