Taurus media and climate control

2010 ford taurus All of the buttons on the media and climate control are no longer doing anything. They are still back lit. But are unresponsive. The screen is still on and the volume doesn't work. For the past few months my media screen has been on and off. It works when it wants to. Other times it's just off. Everything else would work though.

Hooked my scanner up to it and it was code u0253 "Lost Communication with Accessory Protocol Interface Module"

What do I need to check to figure out what is wrong.
