Abstract: A suspension system which upon detecting a fault such as a failed sensor, takes an inventory of the remaining operational components in the system and attempts to use the remaining operational components to keep the ride height and leveling system working. The system may open a cross-flow valve operating in fluid communication between the airbag in the corner containing a failed component such as a failed valve and the airbag in the corresponding opposite corner in that end of the vehicle to average the height data in that end of the vehicle and use the remaining operational valve in that end of the vehicle, while leaving independent or enabling the independence of the airbags in the corners of the opposite end of the vehicle so as to maintain a virtual three airbag suspension system.
