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
- PCM
- Electronically controlled throttle body
- Clockspring

The speed control system is controlled by the PCM. The speed control system is designed to maintain a selected vehicle speed between 48 km/h (30 mph) and the maximum limited vehicle speed. 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:

- Turning the speed control system on.
- Setting and maintaining the desired vehicle speed.
- Accelerating the vehicle speed.
- Decelerating the vehicle speed.
- Resuming the prior vehicle speed.
- Turning the vehicle speed control system off.
- Canceling the speed control.
