PCM error code PO603 "Help!"
97' f250 powerstroke, 125K miles. Just purchased and had to change the mechanical fuel pump. Bought an Edge Evolution and read the codes before I set her for the tow package when I came up w/ the following code and description:
PO603 PCM Processor
Keep alive memory
(KAM) Error
Anyone know what this is telling me??
