Testing for bad Battery Safety Terminal?

[Corellian Corvette]

Hey all - just picked up a "parts" 4.6is today. Turns out it may be a better car then I was expecting so I may trying and fix it up.

One thing - airbag light is on and previous owner says the problem is the BST.

Car was in a slight rear end collision - no airbags were deployed. He says the problem is the BST on the battery cable.

The car runs and drives fine, actually. Reading about the BST it typically says BST goes bad and the car won't start.

So just wanted to see what folks here had to say. Is it possible the BST is bad but the car still starts? Is there a check for this issue?

Thanks!
