The Variable Assist Power Steering (VAPS) System controls power assist, which depends upon vehicle speed and steering wheel angle. The Automatic Shock Control Module provides a large amount of assist when the steering wheel angular velocity is high, at low speeds and when parking, for example. As smaller amount of assist is provided at high speeds to allow greater road "feel."

With the Ignition Switch in RUN, voltage is applied to the Steering Sensor and to the Automatic Shock Control Module.

The Power Steering Actuator, which is controlled by the Automatic Shock Control Module, controls a hydraulic valve, which determines the amount of hydraulic assist available to the driver.
