Cruise control system operates a mechanical linkage to throttle by means of cruise control module. Cruise Control Module receives input from cruise control switch, brake switch, speed sensor and Powertrain Control Module (PCM).
The cruise control module contains an electronic controller and electric stepper motor. Controller monitors vehicle speed and operates electric stepper motor. In response to the controller, stepper motor moves a connecting strap that is attached to the cruise control cable. Cable moves throttle linkage to vary throttle position in order to maintain desired cruise speed.
