00 f250 with KAM code

[stroked00]

I got a 00 with 235k on it. I went out this afternoon and the truck started but the alternator wasnt charging, the abs light was on and it wouldnt release the shift interlock out of park. I got a 603 code which said it was KAM related. I also got a 1000 code. All Data said 603 was KAM realted and to check a bunch of fuses or possible pcm realted. So I checked the pcm, which was lose, I tightened it about two turns til tight and no fix. Then I pulled it out and cleaned it with contact cleaner and also hose out the plug and still same problem. I live in Wisconsin, so Im thinking it might be ground related with the winter salt, but if it is, where the hell do I start with that. Any idea's, thanks.

The alt guage does work, it read a smidge past 9 and then when I stepped on the brake to pull out of park the guage dipped even more.

Do you have a chip or programmer on the truck at sometimes that will set a p0603 when you change tunes

The odd part is the alt not charging, the abslight on and its locked in park, how are they realted??

[Dave]

Where at in WI im near lacrosse. Those codes can also come if with really low battery voltage

[stroked00]

Just north of Milwaukee, Cearburg to be exact. The truck starts fine, cranks like it normally does

Not sure really how they are related. I would test the alternator with a volt meter and see if its putting out voltage first. Sometimes the kam code comes up from the batterys being disconnected as well.
