I'd get it scanned and see what codes you get.. it can be anything... and i mean anything.. but i agree, steady light means the module is bad. lots of codes is a good indication of a bad module. usually after an airbag deploys, the module has to be replaced or at least, reset. there are lots of ebay sellers that repair your module for $50-$60.. you can also remove the module and buy one 'exactly' the same w/ the same numbers on it on ebay.. just make sure its coming from a car that was never in an accident or never flooded.
the module is on the floor in between the driver and pass seats, underneath the center counsel.
here is some helpful info from my 2006 manual. it shows you what typically needs to be replaced after front impact, side impact, etc...
