I C M KAM error ??...
 

Hey again, fixed my problem with my 99 f250 7.3 now a new code popped up P0603 what the hell is an Internal control module KAM Error? Alligator any ideas? thanks for any info on this.

Do you have a chip or programmer installed? Have you disconnected the batteries recently?

If so, don't worry about that code. Otherwise, it is what it says and the internal self-test of the PCM shows that there is a problem.

yea i do have a programmer and i just replaced both valve cover gaskets and replaced all 8 glowplugs this is the first time i have had that code pop up so i thought something was wrong or i did something wrong. your not the first person to tell me that so i really appreiciate your advice. this forum is awsome. all of you on this site are just fantastic. I cant thank you all enough for what you do here. THANK YOU Sincerley Bernie Olson
