hey all,
i need alittle advice. i need to remove my steering wheel to do some work
on it, but i'm not exactly sure about the airbag unit. what causes these
things to go off, and if i take off the steering wheel (and remove power
from the airbag) will it go off? additionally, are there any other
sircumstances that would cause it to go off during this procedure?

any help is appreciated
