Its job is to maintain a continuous electrical current to your airbag to insure the system is working properly until it is activated to engage your airbag..
You can either gamble on replacing the Clock spring assembly or you will have to take your car some place that has the SIR diagnostic tools to diagnose your problem..
They use a tool that hooks up to the Clock spring that sends a certain amount of Ohms through the wiring to see if the code clears and the Clock spring is bad..
Then if that checks out then the sensors in the front of the car have to be checked..

ok that makes some sense. i just bought the bag because it was cheap so why not. i think i know someone with a scantool capable of doing that test. thanks!

The AIR bag light can be set due to a few problems, most deal with the electrical connections, but there is a sensor failure that is somewhat common.
1) The most common is a bad ground. Ffor the Airbags is to the post that is located under the hood, near the red plastic + battery power distribution block. Make sure that's good and all the wires are in good condition.
2) Power is supplied by either the #1 or #2 (differs on some years) pin on the harness located under the dash behind the glove box (Yellow connectors)On on the passenger side, and one under the steering column (again yellow) provides power to the Steering wheel air bag.
** I’ve never played with the airbags myself, but I believe if you disconnect the wire the light will go out? The GM manual has a large and complicated section on how to diagnosis airbag failure. **
3) There is part inside the steering column. It is fairly easy to damage. Happens allot when people are installing headers and have the steering shaft removed, it you turn the steering wheel with the shaft disconnected there is no stop, and this breaks it. (what ins0mnia24 already addressed)
** WARNING ** Be very careful when working on these, if you make a mistake you can set the air bag off! Common for the passenger side air bag lid to flip up with enough force to break the windshield! ** (and we thought the OPTI design wasn't good!)

yeah i think thats exactly what i did. i will try doing what ins0mnia said. thanks! oh and i was in the airbag computer not the pcm. don't know what obd-I calls it but basically the bcm.

i am going to ask my buddy and mention this too. see what he's got or knows who has it! thanks
