I have a 6.4 with a P1633 KAM voltage low. I checked the fuse it was good, checked pin 46 at the PCM it also had battery voltage. I condemned the PCM. Had a new one installed by Ford. Well I have the same issue now. Still have good voltage going to the PCM. Yesterday the TCM would go on and off line, sometimes I could get in it with my scan tool sometimes I couldn't. The shift indicator light would go on and off with it. I'm at the end of my rope. Any help would be greatly appreciated.
