When the rear streering is engaged electricly, it goes into gear but a light comes on that says;"Service". The steering works for that one time and then disconnects or goes out of gear and back to two wheel streering. How do I service or take care of this problem myself?

Check the wiring connections for the Quadsteer. The service light came on, on my Quadsteer, and the connector simply wasn't plugged in all the way from the factory.
