I stated it incorrectly, module is where serial no. is giving the problem.. I was a dealer for many years in this area-used cars and motorcycles. I am almost 75 and have built wrecks for 50+ years before back went out. Chrysler has the worst record about air bag lights. Had a factory rep come here to turn air bag light off, after 5 weeks sitting there, he said since truck was wrecked, he would not deal with it any more. Thru another forum about Dakotas, found out the sensors on the passenger seat were shorted out in the wreck. I already knew the seat had to have weights put on seat to reprogram the computer. Ford is almost as bad, not sure about GM, don't fool with them.
