2018 Ram 3500 Laramie crew cab long bed 6.7 l Cummins

I'm hoping somebody has an idea to help.

I had pulled over in a truck stop left the truck idling with AC on while I crashed a little while. Woke up to the dash being off, the wipers going and the truck would not shut off.

I finally had to pull one of the relays under the hood to get this truck to shut down and it has been dead ever since

I ohmed out every single fuse and swapped out every relay in the TIPM (PWR Distribution)

I even completely unplugged TIPM, took it out, blew out and made sure it was completely clean before putting it back in.

No power to OBDII in order to run diagnostic AlfaOBD on it to pull codes.

I've never had any problems even the smallest with this truck and I've owned it since it was virtually brand new.

Anyone have any ideas?

I know the RF receiver might be involved but I haven't found a way to test it, another is possibility of it being Body Control Module, again don't know a way to test it other than going through the OBDII port

I have pretty much run out of ideas and of course no warranty left on the truck even extended warranty so everything's out of my pocket that's why I haven't taken it to the dealer shop

If you have any information please let me know here and you can also send me an email at [email protected] if that's easier.

Really grateful for any help I could get guys!
