With Programmable Ride Control

PURPOSE
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 speed and when parking, for example. A smaller amount of assist is provided at high speeds to allow greater road feel.

OPERATION
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.
