Cruise Control System Operation
2000 Chevrolet C Tahoe 2WD V8-5.7L VIN RSECTION Cruise Control System Operation
For gasoline engine applications, the cruise control module maintains a desired vehicle speed under normal driving conditions.
The following items describe the typical operation of the cruise control module:
1. Before the cruise control system will operate, the cruise control module must see an input from the stoplamp switch by depressing the brake pedal.
2. The cruise ON/OFF switch must be in the ON position.
3. Press the SET button in order to activate the cruise control module.
The cruise control module stores the last vehicle speed input from the Vehicle Control Module (VCM) into a memory.
4. Use the stepper motor (part of the cruise control module) in order to increase or decrease throttle position.
Throttle opening will vary depending upon the load (going up or down an hill) in order to maintain speed.
5. Turn the cruise ON/OFF switch to the OFF position or apply the brake in order to turn the cruise system OFF.
