Not to worry. Typical code when using a programmer. Your PCM is fine. For more info about P0603 just type 0603 in the Search This Forum box at top of threads list.

I have the diablo as well and anytime you change tunes it will show this code for awhile. Just clr it with the diablo and your good to go. Or dont clear it, it doesn't matter at all. Oh, and it's not just the diablo, I believe anytime you use a chip/programmer and change anything this shows up. Totally normal!

When I had the Daiblosport Predator Programmer it did the same thing. Chips won't have the code but either way it doesn't matter - you are good to go.
