Just drive you truck normal on hwy and in city, it will set all monitors eventually, if you remove your battery cable or clear codes with handheld, you will have to start from square one, clearing codes also clears the monitors for emissions, that's the crappy part. Hopefully you are close to stock, if running a tune, it sometimes takes longer to clear all monitors, but having your factory tune on the computer is the better way to go, trust me, had to jump through all kinds of hoops here in Cali a few years ago
and P1000 will never go away, this is showing your computer has a tune, not factory
