Cruise Control Module
1998 Chevrolet Lumina V6-3.8L VIN KSECTION Cruise Control Module
The cruise control system uses a cruise control module to obtain and hold any desired vehicle cruise speed above a minimum speed of 40 km/h (25 mph). Two components within the module help achieve this:
^ An electronic controller that monitors vehicle speed, turn signal lever, cruise control release and brake switch inputs and operates the electric stepper motor.
^ A stepper motor which moves an internal band (linked to the throttle lever via the cruise control cable) in response to the controller to maintain the desired cruise speed.
