Finally got a VCXNano up and running and have the unit connecting to the truck to retrieve data. I want to change out the airbag module under the drivers seat due to SRS codes - the unit was badly corroded after the interior floor got wet this winter (hole in the floor has been patched). I have another used unit that I want to change out but I was under the impression that I would have to do a VIN relearn with the new unit after plugging it in. I have navigated the Supplemental Restraint menu on the Tech2 software and I can't find anything of the sort - would it be under the BCM menu or somewhere else?
