Re: PO603 Code
You should only get that code when you unhook the batteries.
Wrong on some the fords they have built into the pcm/the truck tex code. You will get this dtc
without unhooking anything. This code is normal and you dont need to worry about it.This dtc
only set when you run a new program and or unhook your batterys. I have already been through this dtc
with edge and Bill at powerhungry.
