If the Calibration Code is unknown, whatever part that needs to be replaced on a specific truck has to be compared in all the specific parts lists to see if it matches.

The parts must match the computer, otherwise the truck won't run correctly. After spending 35 years as a partsman, I retired in 1997 because I was fed up dealing with this crap!

And I avoid...whenever possible, dealing with it on FTE, cuz if the Calibration Code is unknown, the member is up **** creek without a paddle!
