WARNING: This page is about a different car, the 2009 Mercury Sable, 2009 Ford Taurus X, and 2009 Ford Taurus. However, it is still accessible from the selected car via links, so may be relevant.
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 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:
- 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.
