Hey guys, finally got time to work on it again! Got the PCED and breakout box, neither helped fix any of the issues I was experiencing. Got the EVTM and with the help of that was able to clear out the previous codes. Now I have a new code, 564 ElectrOD FAN(EDF) circuit failure. The fan turns on when I put the key into the run position and doesn't turn off until I turn the key to the off position. My IRCM has been removed and replaced with separate relays. The only part I was not able to recreate in the fan circuit was the solid state voltage inverter. I have tried to find more information about it but have come up with nothing. Does anyone know if that missing would cause the 564? I have tried swapping the ecm with a different one but the code is still given so I don't think it's an ECU issue or a fan motor since it's continually running. Haven't tried starting it up yet, will be attempting that in the next couple days depending on the weather. Thanks again for the help everyone!

Voltage readings from pin 51 with the fan off and on would be helpful if no one has info on the voltage inverter

Can you not find another IRCM and return it to a stock config?
That is most likely why the fan is staying on
There is a lot to an IRCM besides the relays
The logic module and all that they do not explain in books or school

I could but there is no spot where it's not going to be exposed to the elements which caused the original one to fail. That is why I chose to separate it and use waterproof relays instead of of buying a replacement

Put it in a waterproof box and use liquid tight cord connectors where the wire bundles go into the box?
