Airbag light- module failure?

[Wilson01S]

I have an airbag light on my 2001 S that has been on since it came back from the bodyshop this spring. Since I was working so hard to get all the mechanical bugs out of the car I neglected the airbag light until today.

I scanned the Airbag system and it has a code 195? I googled this and there were a few threads on this about the car being jump started with the ignition on (which I can almost GUARANTEE happened while at the body shop) and causing the airbag module to fail.

Is there some substance to that?

Can I get an airbag module from a wrecked 2001 S, or someone parting a car out, plug it in and it will work?

Does it need to be activated?

What are the proper steps here while simultaneously avoiding the dealer?
