G'day all
Like it says, Error codes PO232 . (Fuel Pump Secondary Circuit High)
PO603. ( Internal Comtrol Module Keep Alive Memory (KAM) error.

What I have done is change from Tow mode to Race mode on my Edge Evo programmer. I have been giving her a boot full to see how much difference it makes. I also cleared the codes and took her for another run and it came up with the PO603 code again.

 

The P0603 is from the Edge. Its nothing to worry about. Its just from erasing the PCM and reprogramming it. Completely normal. The other one is up to the experts to explain.

 

As long as you're running a chip or tuner you should expect to see the P0603 code. Has to do with Non-Ford programming being on a Ford PCM. Completely normal. Nothing to worry about Brian.

If random codes pop up from time to time, but don't come back soon after you clear them, I'd ignore those too. Just a side effect of running a chipped truck.
