Cruise Control: Description and Operation

Circuit Description
The cruise control system uses mechanical and electrical devices to maintain vehicle speed at a driver-selected setting. The cruise control module receives signals from the main switch in the cruise remote control switch, the stop lamp switch, transaxle range switch (A/T), over drive switch, clutch pedal position switch (M/T) and the vehicle speed sensor. The cruise control module provides signals to the cruise control actuator and the transaxle control module (A/T).

With cruise engaged, the cruise control module sends a signal to the transaxle control module that prevents the transaxle from continuously downshifting and upshifting to maintain the set vehicle speed when going up a long grade or hill. The cruise control module incorporates a self diagnostic feature.
