I have no idea. If you have access to another DIC you could plug the wiring into it and see what it says, that way you have eliminated the DIC as your problem(although I doubt that is the problem, you would know for sure....) If it is an open circuit the wiring most likely has been cut or disconnected somehow......no way to tell though for sure without troubleshooting the wire itself. Follow it and see if you can visually see anything wrong with it.
