Cruise Control System Description
The cruise control system is used to control vehicle speed to a user-selected value and an accuracy of ± 2 km/h (1 mph) on a flat level road ± (2% grade). The cruise control can be set at speeds at or above 39 km/h (24 mph) with a lowest tap down speed of 32 km/h (20 mph).The cruise control system consists of the:
^ Cruise Brake Switch
^ Cruise Clutch Switch (manual transaxle)
^ Cruise Control Module
^ Cruise Control Switches
^ Cruise Control Throttle Cable
^ PCM
^ Stop Lamp Switch
Unlike other systems, this system is fully electronic and does not require vacuum or a vacuum servomotor to control movement of the throttle. To control throttle movement, a cruise control throttle cable connected by a cable strap from the cruise control module pulls on the throttle cam at the throttle body. The cruise control module uses an electronically controlled stepper motor to move the throttle cable.
A lash learn feature is utilized in the cruise control module. The module uses electronic circuits and software to learn the amount of lash (slack) in the cruise throttle cable eliminating the need for manual adjustments when a non-adjustable cable is used. The cruise control module can learn up to 4 mm of lash and updates (readjusts) every 30 seconds. Vehicles with an adjustable cruise control throttle cable will need to be adjusted as per the "Cruise Control Throttle Cable Adjustment" procedure.
