Suddenly, Airbag light
Drove out this morning, no light. Came home and went out an hour later and cranked up and now I have an airbag light. I have turned it off and started it a few times and the light remains on. I had the airbag TSB done a few months ago, but this is the first time I have had the light come on. Short of doing the reset by unhooking the battery, any more suggestions before I hand it over to the professionals? 
You can unbolt both seats and check the wiring harnesses under them to see if something came loose. An unplugged or loose harness there will trigger the aigbag light. I learned this when I removed my seats to change the LED's in the seat belt receivers to white (with the help of a forum buddy!). If you take on this procure, follow the first few steps to give you access to the underside of the seats.

Should be easy

Found it! I ran Techstream and it had thrown a B1135 Half Connection at center SRS connector. I remembered I had been monkeying around in the center console trying to find a bad connection from my Beatsonic to the radio and must've bumped something loose. I pushed on the connector at the small box just under the seat heater switch and it looks like it cleared the code. Who knew? I am keeping my fingers crossed that cured it. My wallet was starting to worry. LOL 
Edit: I just looked it up and apparently that little box is NOT the center connector. The center connector is larger and further forward but still under the console. At any rate, whatever I wiggled and pushed seemed to cure the issue.
