Circuit Operation

The Cruise Control regulates the speed of the vehicle in response to driver commands.
The Cruise Control Module contains electronic circuitry and a stepper motor. The other system components are:

^ Cruise Switch
^ Set Switch
^ Brake Switch
^ Clutch Switch
^ Vehicle Speed Sensor

The Cruise Control Module receives voltage from the GAGES Fuse in RUN or START. A speed signal is received from the Vehicle Speed Sensor Buffer (DRAC). The driver gives his input to the Cruise Control Module through the system components previously listed. The Cruise Control Module circuitry receives the driver's input and generates electrical pulses. These pulses cause the stepper motor and its output reel to rotate. The throttle is controlled by a cable wound on the output reel. The Cruise Control Module also contains a clutch which releases the cable when the Cruise Control System must be shut off. This clutch will operate when the Brake Pedal is depressed, the Clutch Pedal is depressed, the Cruise Control System is turned off or the Cruise Control System detects a failure.
