PRINCIPLES OF OPERATION

Vehicles that are not equipped with air suspension have a stand-alone variable assist power steering (VAPS) module.

The air suspension module is linked to its own data link connector (DLC). The air suspension module controls the air suspension and the VAPS.

The air suspension module is used to monitor and control the VAPS system. The VAPS system controls the level of power assistance available to the driver based on vehicle speed and rate of change in steering position.
