Just to make things a little more clear.... if the air bag light is
illuminated or flashing, it will not deploy in the event of a frontal
impact.... it can, however, deploy if someone unfamiliar with the system
gets into some intrusive testing....
These are explosive and/or pyrotechnic devices.... There is no "fudge
factor" allowance and they are very, very unforgiving when goaded.
When someone has to ask some of these questions, we are already aware of
their knowledge base... we are not aware of their skill sets nor their
familiarity with accepted practices. I am not trying to drum up business for
techs I don't know or shops I've never heard of.... but I think it prudent
that none of us try to drum up business for Emergency Rooms, as well....
FWIW.... Many SRS systems (and ABS sytems as well) will set a "low system
voltage code" that will not go away until it is cleared with a scan tool...
In some cases it can take in excess of 40 key cycles to self-clear this code
and allow the light to go out. While a bad battery is one consideration (and
if the battery is three years old or older) and replacing the battery before
it fails is a wise choice, something as simple as disconnecting the battery
or pulling the wrong fuse when looking for something else can set a low volt
