Cruise Control System
WARNING: This page is about a different car, the 1995 Cadillac Seville, 1995 Cadillac Eldorado, and 1995 Cadillac DeVille. However, it is still accessible from the selected car via links, so may be relevant.
Cruise control is designed to maintain a desired vehicle speed greater than 25 MPH. System capabilities include cruise, coast, resume speed, accelerate, tap-up and tap-down.
Cruise control system operates a mechanical linkage to throttle by means of a vacuum motor-operated servo. A solenoid-operated valve connects the vacuum motor to a vacuum tank. Servo is controlled by Powertrain Control Module (PCM).
