When I purchased my truck it was a repaired total ( except the airbag ) but I just purchased one through Ebay. The light flashes a 32 code which is the clockspring. What I was wondering, do I need to replace the crash module also, and if so How!!! I think the truck was a roll over, but I am not for sure because it was repaired before I got it. Is there a manual that I can buy or a web page the explains the diognostic testing and install procedure for my truck.
