When i bought the car it had a hypertech tune on it a few weeks ago i tuned it back to stock specs. Today i got a hair up my ass to powertune it.
When it did dtc scan it had no codes. so i let it flash it to 93 octane. everything seemed good it said it was sucessful and i could tell it has more power.
so later tonite for ****s n giggles i ranthe hyper tech it to adjust rev limit. but before it got to the flash it has to check for dtc's and this is what came up. DTC code: P1000 OBD-II Monitor Testing Incomplete.
so i cleared the dtc and flashed it back to stock spec to see if that would maybe been the problem to get that code. . it said the tune was back to stock successful i drove it home 13miles and rechecked it before goin in.
well when the hyper checked for dtc's code p1000 came up again. so whats going on and how to fix. oh also today i did that thing to turn off seatbelt reminder. but i dont think that had anything to do with it cuz later when i did the hypertune it checked and was clear of any codes at that time. check engine light aint on either and it seems to be running normal what should i do. please and thanks oh 2001 gt 1 MORE THING THIS SITE ROCKS!

All sighns lead to your drive-cycle was never complete. You can let the code stand and see if your car starts and finishes the drive cycle over again.

Or clear the code let the car sit for a while and see if it finishes the drive cycle.

Any sensors turned off with programmer?

What is = your drive-cycle was never complete.

any sensors turned off? no i didnt turn any off thru the hypertech when i turned it back to stock tune. but when i did the first 93 tune i think i raised the top speed for z rated tires 155mph

i cleared the code when i got home and found it still had it after changing back to stock tune. so after clearing ths dtc i came in for the night see what happens tomorrow.

You need to drive the car to clear the readiness monitors. A P1000 means they have not all been run. Whenever you disconnect the battery to clear a code you are left with a P1000 code. Really this is first hour of OBD2 training.
