All I could find was Internal Control Module Keep Alive Memory (KAM) Error. Did you try to clear the codes then check them again?

I Google'd it. I found it can be caused by disconnecting the battery, by the tuner itself, or the PCM. I also found it almost always means nothing. I am not a tech and did not stay in a Holiday Inn last night.

more than likely it came from your tuner. bad thing about a 6.0 and p0603 is it affects shift points, fuel mileage, and your air conditioning by a cycling strategy in the pcm. now stroker, do you know if you have the 03 style engine or the late build. look for the icp sensor on the right valve cover if you dont know. if you have the 03 style, you need to get your tuner updated, because it is going to effect your vgt learn cycle.

Hey guys thanks for all the help I did have to remove my drives side postive battery cable to get the air filter housing out {very tight} I did clear the code and it has not come back after driving it today. You think the air filter would be alittle easier to get out and back in on these trucks. I can tell you guys that I replace my air filter with the K&N but after I heard about the turbo dusting and engine dusting put my factory air filter back in. But my not going to mess up my engine by using a air cleaner that does not filter the air as good. I do think my exhaust temps went up just a little after changing back the factory air filter.
Thanks,
