Oh, ok that seems like a relatively simple procedure. It was sounding like the entire module needed to be reprogrammed. That didn't make sense to me if the valve body was interchangeable similar model, similar year, etc.it wouldn't need any programming. Sounds like it just needs to be registered kinda sorta.
