Cruise Control: Description and Operation
Cruise Control
The cruise control system consists of the following components:
- Cruise control switches
- Cruise control deactivator switch
- Cruise control indicator
- PCM
- Electronically-controlled throttle body
The cruise control system is controlled by the PCM. The cruise control system is designed to maintain a selected vehicle speed between 48 km/h (30 mph) to the maximum limited vehicle speed. The cruise control system is controlled by the steering wheel mounted switches (ON, OFF, SET+/SET- and RESUME), and the brake pedal. The steering wheel mounted switches are hardwired to the PCM.
During normal driving the vehicle speed may vary slightly from the set speed due to road conditions. The vehicle speed may fluctuate when driving up and down a steep hill. If the vehicle speed decreases more than 16 km/h (10 mph) below the set speed, the cruise control disengages.
