Alright through another code, P1000.... Please help....

 

If you cleared the previous codes, the 1000 code is telling you all test have not been completed.
If no other codes are present the truck needs to be driven in enough drive cycles for the PCM to looks at all tests then the code 1000 will clear if there was no further test failures.
A sprcific drive cycle is perscribed to do this but normally it will clear after a week or two of extended dtiving that hits all the points in the drive cycle.
This code can't be cleared by removing power and rebooting the PCM.

 

p1000 code is pcm reset, memory clear
It will go away on its own when all systems (catalyst, egr, O2, Ho2s, fuel., etc....) come back online. They go temporarily offline when the pcm is reset and reboot over a few miles of driving, in Lehmans terms
