WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2000 GMC Yukon, 2000 GMC C3500 HD, 2000 Chevrolet Tahoe, 2000 Chevrolet Suburban, and 2000 Chevrolet Pickup. However, it is still accessible from the selected car via links, so may be relevant.
The cruise control module contains an electronic controller and electric stepper motor. Controller monitors vehicle speed and operates electric stepper motor. Responding to controller, stepper motor moves a connecting strap that is attached to cruise control cable. Cable moves throttle linkage to vary throttle position in order to maintain desired cruise speed. Cruise control module contains a low speed limit which will prevent cruise control system engagement when vehicle speed is less than about 25 MPH.
