Cruise Control: Description and Operation

SPEED CONTROL

The speed control system consists of the following components:
- speed control switches
- speed control deactivator switch
- speed control indicator
- powertrain control module (PCM)
- electronically controlled throttle body
- clockspring

The speed control system is controlled by the powertrain control module (PCM). The speed control system is designed to maintain a selected vehicle speed between 48 and 200 km/h (30 and 124 mph). The speed control system is controlled by the steering wheel mounted switches (ON, OFF, SET+, SET-, CANCEL, and RESUME), and the brake pedal. The steering wheel mounted switches are hardwired to the PCM.

The speed control functions include:
- turn the speed control system on
- set and maintain the desired vehicle speed
- accelerate the vehicle speed
- decelerate the vehicle speed
- resume the prior vehicle speed
- turn off the vehicle speed control system
- cancel the speed control
