How does Autoride Suspension work on a Chevy Suburban?

There are frame to suspension sensors, which feedback how far down the frame is sitting down on the suspension. Each shock is an air shock, air-tube connected back to a set of air solenoids, fed by an air pump. If the sensor feeds back that a particular corner is low, pump turns on, and that solenoid opens to allow the pump to pump up that shock.
