I'd actually prefer if they didn't use acronyms at all. There was once an excuse for them when scanner screen space was more limited. There's enough real estate on the screens of the new scanners to spell things out so the mechanic doesn't have to waste his time getting out his secret decoder ring to decipher what these pids are. This is just one more area where the aftermarket scanner companies could sure help us out - hint HINT HINT
