    need help don't understand this. put burnt original vaps/air ride mod in and no air ride code but has a vaps code and of course parasitic draw. wife said steering would get stiff and go away. think I got a bad module?

    think I figured it out. new vaps/air ride module needs to be configured.

    Are you sure you are not getting binding in the steering shaft U joint? I got a used module off Ebay for like $20-25. It's behind the glovebox, easy to get to.
