Question code P0603 spent $3000.00

So I went out to put my truck back to stock from my super chip and I pulled the code before I did it, Po603 came up The P0603 code possible causes:
Battery or PCM has been disconnected.
Battery cables loose or poor connection.
Battery discharged.
Open in KAPWR circuit.
Blown fuse.
PCM.
I never disconected the batteries or the pcm yetand I checked # 2 fuse and it is not blown, what is KAPWR ciruit ?????????????????????????????????

This is a common code for a truck with a chip/programmer.

NOTHING to worry about, leave it alone.
