with the SCS connector shorted (blue 2 pin plug behind glovebox) it should flash the trouble code with the key on. if theres no codes the srs computer might not have power...check the fuses at the inside fuse box and that the yellow in secure. after that look for a computer from a junk yard as I do not trust a srs computer that has blown a bag to work right even after it's reset you think does it really work?
