The airbag is a one time use only once it blows it needs replaced.
The airbag control unit is a one time use only as well
The sensors are reusable and self resetting if they didn't get hit themselves and not cracked.

The Airbag control unit is up under the radio center console bolted to the floor in front of the shifter

The driver airbag is same as a legacy of the same era.
There are tamper proof torx screws with the center stub, and they are all really tight, they are factory installed with threadlock glue and are hard to come loose.

You need to unplug the battery and pull SRS fuses when working on this stuff, for at least 30 minutes prior to doing any work.

The connectors have special metal lock tabs and green slide locks to disconnect.

You NEED to make 100% sure the control unit you are going to buy was from a car that the airbags were 100% intact.

If an airbag blows, it can also damage the roll connector for the steering column and it would possibly need replaced.
