Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Cruise Control Systems: Description
The cruise control system uses mechanical, electrical and vacuum operated devices to maintain selected vehicle speed at more than 30 MPH. The cruise control unit receives command signals from cruise control main switch and cruise control SET/RESUME or SET/RESUME/CANCEL switch. It also receives operating signals from brakelight switch, Programmed-Fuel Injection Electronic Control Unit (PGM-FI ECU), speed sensor, clutch switch (M/T) or shift position switch (A/T).
The cruise control unit compares actual vehicle speed to selected speed. The brakelight switch releases system control of throttle when brake pedal is pressed. The clutch switch, shift position switch and cancel switch sends a disengage signal to the cruise control unit.
