once deployed, you need to go back to the dealer, as a Star Diagnostic System is the only thing that can reset the bag light. Your whole system is shut off right now with the light on. I would replace the bag, and go to the dealer and have it reset. Because the air bag system is off right now. Can't express that enough. You want to take the battery terminal off the positive side before working around the air bags... My body shop forgot to do this when repairing my door skin. Unplugged the bag, on came the light, off went the system...thank goodness I know the owner of the dealership....or it would have been $100...
