Hello Guys! Thanks for having me! I have an o5 f350 srw 6.0 that the ipr voltage died coming from the PCM so I got a reman one. Put it in (Yes followed ground disconnect procedure) and fired right up just fine. but now my Tow/Haul light is flashing and if you put it in gear you can tell its trying to go forward and reverse. Locking up. so I shut it off and ran a scan on it. got a uo100 code=Lost Comm with ECM/PCM. I can put my old one back in. it wil crank and run if i put 6 volts on ipr and tranny is real happy with no issues. so..........send back PCM??? And is TCM inside PCM??? Thanks for any help!!:flag:
