As a chevy tech let me tell you what this means. You have a problem with your
airbag system. You didn't mention what type of car you have, not that it
matters though. There are several components that are all controlled by the
Arming sensor or Diagnostic Sensing Module, depending on what year and type of
system you have in the car or truck. There are driver and pass. airbag
modules, forward discriminating sensor(s) arming sensor(s) s.i.r. coil (located
in the steering column) All of these components have certain resistance values
and voltages that the arming sensor looks at constantly. If there is a problem
on any circuit such as a short to voltage, short to ground, open
circuit,etc.... the Module triggers the Air Bag light to illuminate notifying
you of a problem that needs to be addressed. Take your car to a dealer that
specifies in the make of your auto. They are certified to work on air bag
systems and have the correct diagnostic equip. to find the problem. Be
prepared to break out the wallet if any parts need replacing. Just an example,
a passenger side airbag for a Cavalier or other small pass. car can cost around
800 bucks. Not cheap. By the way you didn't mention if the bag or bags have
been deployed previously. If so, you'll have to replace the air bags (did you
know they use solid rocket fuel to deploy them at 190 m.p.h.) the s.i.r. coil
and arming sensors. All this needs to be done to ensure the next time they
need to deploy, all components are good. A s.i.r. coil has 36 volts run through
it when it deploys a drivers side air bag. All this goes through a small metal
tape wrapped inside the coil housing. The tape resembles the stuff just like a
stereo cassette has in it. This thin material is not reliable for two
depoyments of 36 volts and all the amperage that passes through it. Good luck
on your system. Any more questions,,feel free to em me. Dave
