What is your question?
My car shows no other signs/symptoms pertaining to a P0603 code, other than the fact the code appeared while i was on a long trip after i had disconnected the battery many times while i was installing HID lights. Will the PCM relearn in time my driving habits, or did i really screw something up that needs to be replaced?

The PCM will relearn. I'd would make sure you wired in the HID headlights correctly. If you used wiring associated with PCM you could damage it. The P0603 code is for low power supply to the PCM.
