AIRBAG MIL: Armchair Diagnosis

So my airbag warning light came on the dash last night after two consecutive causative factors:
1) I hit the horn...hard
2) 30 seconds later I yanked the passenger seat forward to see what was rolling around in the back seat. There was also a book someone had kindly wedged under the passenger seat from behind, which I found later. When I looked up, the MIL was on for the airbag. Quick inspection reveals nothing disconnected.

I was wondering if there were common failure parts on these cars for the SRS system? I have a '99 9-3 FWIW. Also, how specific is the code for system failure? As in, will it point to the problem eg "clockspring resistance too high"?
Getting the code read is the intelligent thing to do, however, the cost of having someone plug into OBD and telling me something I may already know is more than the actual part to fix it.
Thanks in advance,
-Cm

On my '97 900, the light came on due to a bulb in the dash burnt or burning out
? That's what they said when they hooked up the Tech11.. It's stayed off for a few months now.

Meh, I guess I'll have to take it to a mechanic to get the code read.
Dammit.

Getting the code read would probably be easiest to tell you where it is, but you could maybe try to disconnect/re-connect the plug under the seat where the book was.

On the T7 cars, there's a resistance check, and once it fails a check, it takes maybe 10 or 15(?) ignition on/off cycles where successful values are read before it will eventually turn the lamp off--I forget how many it is exactly but it's more than you would think. The T5 stuff may be different though.

This^. It took my 9-5 like a month for the light to go out after I had removed and replaced the seats.

Does anyone know a good Saab tech with a Tech II in the Boston area?

Which is the connector for the airbag on the passenger seat?
It is damn cold here and digging around under there for wires is less than pleasant with gloves off.
Thanks,

They're usually bright yellow, two wires. I think when it's dry and cold you want to touch a ground or wear a static strap before messing with them--I do anyway, just in case.
