BMRfixit has the good oil on this one, check his post, that is what I came up with as well.

Thanks for your advise on the airbag problem. I've checked resistance with airbag removed and module unplugged and get 0 resistance from pin to pin. My code has been 34 which means: "Drivers side airbag circuit low resistance or shorted" with airbag plugged in. When I unplug airbag and powerup light code flashes 32 which means: "Drivers side airbag circuit high resistance or open" So, my ohm test must be inaccurate due to a shorting strip in plug or something.
Could the airbag plug be defective?

I would look very closely at the connectors and the shorting bar in the air bag assembly. The fact you get a code for an open circuit with the air bag unplugged proves the wiring is good. Finding 0 ohms between the two wires is correct when it is unplugged from the computer. That's because there's a shorting bar in that connector too. That way static electricity from your feet on the carpet won't pop the air bag if that connector is left unplugged.

There isn't anything inside the rocket fuel canister that can be shorted so that just leaves the shorting bar. The only other thing I can think of would be if there are different resistors in different model air bags, and you have the wrong air bag for your car. Even though they might bolt on and fit, there might be a difference between model years or car models.

I have the original, deployed, airbag and when I plug it back in the code reads 32 which means: "Drivers side airbag circuit high resistance or open." I'll cut it's plug off and install it on the replacement airbag (same polarity) being cautious to not permit any static charge.
