Cruise Control: Description and Operation

DESCRIPTION

The speed control system is composed of ON-OFF, SET-ACC, COAST and RESUME switches. The system contains vacuum hoses, servo (throttle actuator) assembly, speed sensor, amplifier, check valve assembly, and depending on model and year, a clutch switch, a manual lever position switch, stop light switch, or vacuum dump valve, an actuator (servo) and an actuator cable.

OPERATION

To operate speed control system, engine must be running and vehicle speed must exceed 30 mph. When ON-OFF switch is actuated, the system is ready to accept a set speed signal. When vehicle speed stabilizes (above 30 mph), and the ON switch is engaged, the operator may depress or release the SET-ACC button. This speed will be maintained until a new speed has been set, brake pedal has been depressed, or the system is turned off.
The vehicle speed may be reduced by applying the brake or clutch pedal and then resetting the speed using the method outlined above or by depressing the COAST switch. When the vehicle has slowed to the desired speed, the COAST switch is released and the new speed is set automatically. If the vehicle speed is reduced below 30 mph (48 km/h), the operator must manually increase the speed and reset the system.
