Well, lets see... you can toy around with it, possibly blowing the
airbag or perhaps  ending up with an airbag system that won't
deploy... or you can pay someone qualified to fix it.

Your choice.

The airbag system is not something i would call a "Do it yoursef job",
more like a "Destroy it yourself job", on mine 98 9-5 it was the
wiring behind the airbagmodule in the steeringwheel that had broken.

You need to visit a workshop anyway, to get the error code resetted,
and they can also check what is causing the errorcode as that
information is stored in the controlmodule.
