Kaodtech Security Module Bypass + JScan = Christmas Party on Dashboard

[POC911]

I had successfully modified tire size, tire pressure and gear ratio (after re-gear) on my Jeep JLU before. Thinking it would be just as simple to mod my new 2024 Power Wagon. After changing the tire size and tire pressure threshold, I turned off the power and then started the engine. All hell came loose. All warning lights came on and got a U1412 code. Sent it to the dealer and they reset everything; and had to pay for an expensive car wash.

I suspect what I did wrong was not changing the setting one at a time and restarting after each change. Did anyone have similar issue before?

Have to do ABS initialization process after tire size for it not to get pissed off. Make sure you’re in level ground and do that to clear lights

Thank you @Enve46. Do I need to recycle (Run --> Off --> Run) before ABS initialization?

It should do that on its own. It’ll tell you the steps to take
