Cruise control is a speed control system that
maintains a desired vehicle speed under normal dri-
ving conditions. However, steep grades up or down
may cause variations in the selected speeds. The !
electronic cruise control system has the capability to
cruise, coast, resume speed, accelerate, “tap-up” and
“tap-down”.
The main parts of the cruise control system are the
functional control switches, speed control assembly, actuator, intermediate link, auto-cruise control mod-
ule assembly, speed sensor, and the release
switches.
Depending upon the year and/or model of your
vehicle, the cruise control system is either vacuum or
electronically controlled. The cruise control module
assembly contains a low speed limit which will pre-
vent system engagement below 25 mph (40 km/h).
The module is controlled by the functional switches located on a lever on the steering column or steering
wheel and on the instrument panel.
The release switches are mounted on the
brake/clutch/accelerator pedal bracket. When the
brake or clutch pedal is depressed, the cruise control
system is electrically disengaged and the throttle is
returned to the idle position.
