Airbag light- module failure?

[Wilson01S]

So today I stopped into my local indy and had the airbag system scanned with a durametric. It has an airbag module internal failure code. He tried to reset the light and it comes right back. Has been counted over 100 times- hard fault.

My guess is the body shop jump started the car (since it had a weak battery when I dropped it off) and had the key on.

If I buy a module out of a wreck/parted out car is it plug and play? Is there a serial number specific to model/trim/year? Does this need to be initialized by a dealer, or can the durametric initialize it?
