p1000
Are you tuning the truck? The P1000 is "Onboard diagonstic not complete" The code will go away after driving for 50-100 miles after the tune. It's nothing to worry about but if you go for emissions or inspection it could be a problem.


...gotta be specific to the tuner module. The code series goes from P(0)010-P(0)849; there is no (0)000...at least that's what my scanner users' guide shows.
