Need help from experienced CanBus Techs Service Mangers

[Boatman22]

Driving on the interstate this morning running about 70 and the dash went crazy. Everything started flashing and bells going off. The truck ran fine until I slowed down in the slow lane. Wipers started going, no tach speedo nothing on the dash read except the all warning lights still going off. Got off on my exit slowed down to make a turn no power steering and could not go over 25 mph. Stopped turned the truck off, restarted and everything fine. Got about a mile and everything start going off agai, but this time The dash had No CanBus. Got home and the the shift knob would not work and the truck would not turn off. I keep pushing the on/off and it finely turned off. Put an code reader on to clear code and had 43 DTC! Cleared all the codes started the truck and all the lights started and bells light started going off again. Any suggestion an what to start checking? 2023 1500 DT 5.7 10700 miles.

Posted this a few weeks ago. Received a message from the dealer where the truck was towed too. They said that there was a splice to the wiring harness on OBD2 that was more than likely the cause of the problems. (Attach a photo they sent) I told them that was done by the selling dealer for a lojack install and I removed the module in Nov 2023. The SM said that they need 3 hours to diagnose time as this would not be covered by warranty to see what needs to be done. He also attached two sheets of codes that were pulled by the tech. Still don't know what's wrong with the truck. Any advice or information would be greatly appreciated.

Update: I got a call from the dealer stating the problem was caused by the EPS "Electric Power Steering Rack". Said that it has a short and that Ram is aware of the problem and it will be covered by warranty. Bad news no racks are available with no ETA on when they will be.
