I successfully reset mine last night. It's soooooo nice not to have to hit the mode button to clear the dash display, and look at that red airbag light anymore!
The code was set when my clock spring broke. I fixed the clock spring, and had hoped the light would go out on it's own after a few start ups, but it didn't. So I Googled and came up with the necessary info.
This circuit to connect the GM UART 8192 to your PC's RS-232 port (DATA is on Pin-9 of the OBD-II connector by the way):
Here's the cable I made. Worked like a champ! I scored the OBD-II connector from a junked car that had an OBD-II extender. I already had the transistors, resistors and diode.

I have a question that will quickly show that I know jack about what you're talking about. Couldn't I buy this (an OB2 to USB cord) and avoid building the circuit you built?
cost me $45.00 at the dealer after I forgot to plug it back in after stereo install, plugged in in a day later and it would not reset until I took it in
Im going to try this tonight on my 2006 GTO. I started getting my warning light when I removed the passenger seat.
I just got my OBDII connector off ebay ($3.31 free shipping, from Hong Kong). Got the circuit layed out on the breadboard and will try it with a USB->Serial connection on a laptop.
Update:
All clear now
Im not sure when it happened, since I was troubleshooting some checksum issues. After about an hour jiggling and moving components around, I figured its probably the USB->Serial adapter. I noticed later there was no airbag light, or warning graphics. I restarted the car and sure enough, it was gone. I did send the commands a few times, but I was fixed on the laptop rather than the dash, so I dont know when I cleared it. Anyways "WOO HOO".
Hey just be glad the guy actually used the search and found this original thread. Most Mods and long time users here get all pissy when guys don't use the search, so its lose-lose either way :/
Hey now, don't go inserting logic into this place. Not only do we want you to search, but if the shitty AF search doesn't direct you to exactly where we want you to go, then you're still automatically fpfq
I had my airbag light go off when I took the seat out to go racing and didn't know back then that it would throw the airbag code. I tried using this but it didn't work. My neighbor thinks that its the clock spring. I did have the steering wheel off b/c I was going to an aftermarket one but trying to pass inspection now and have the stock wheel on and ran this but still showing airbag fault. How do I check to make sure it is indeed the clockspring and not just me running the program wrong. Everything worked great for reprogramming the cluster.
