just went through this with my v10.. you need to take it to a smog center that knows what they are doing. it took me three places before i found one that knew to scan it as an obd 1 truck.. not obd 2..they did change the regulations, but only on obd 2 vehicles. we should be good to leave our trucks the way they are.. if you are located in the oc area i have a great smog guy now if you need..
First place I went had gotten fined $10k for using the older machine on a newer car and didn't want to run the risk of another on.
Wife took it to a second place that refused to not use his OBDII machine. Hooked it up, failed due to readiness monitors, and then accused me (over the phone) that I tried to cheat by resetting codes
Third place is the one that told me he's not running it that way unless BAR comes down and logs in themselves.
After the third place, I figured to just cut bait. Ref seems the easiest way, just cuts my margin for error to nothing...
ya, the first two placed i took mine had no idea what to do other then send it to a referee.. that would of taken over a month to even get in.. i finally called a around and found a smog place familiar with Federal trucks and said it has to be run as obd 1 since it does not say its obd 2 anywhere on the truck..took it down and passed in 10 min.
