Got tire size/speedometer calibrated. Thank you guys! Saved me $250 from what the dealer wanted to calibrate.

Glad to hear you got it figured out!

So when you say, step away from the vehicle after shutting it down for 15-20 minutes. Do I leave the cables and OBD2 reader plugged in or do I re attach the cables to their original plugs and walk away? Sorry even writing that seems like a question I should be able to find an answer to.

Just make sure everything is closed up and the key is far enough away from the truck so that the computers can fully go to sleep

Thank you all for your info on this!!! I have successfully done the DRL’s, adjusted for tire height, fog light with high beams and the rear turn signal alternating with brakes. Anything else you guys suggest? So much fun!!!

All steps were done without ever putting the ignition in ACC or RUN position, and all working fobs were left in the house (so I could verify that JScan can program for an “all fobs lost” situation).
Connect to Ram DT 1500, then go to adaptation > radio frequency hub settings > RFH pin reading beta > target value = ram 2019-2023 > go.
When the following screen pops up, just turn the hazards on. Don’t bother opening and closing the door and don’t worry about the...

It means the brake lights come back when the turn signal turns off. Default is the brake light disappears on the side you have the turn signal activated. I made a video in this post.
