2022 Peterbilt 389 With Stop Engine Light

I was minding my own business driving against the wind, uphill, and 70mph when I suddenly got the red STOP ENGINE IMMEDIATELY light on the dash display. I pulled over on the shoulder of Interstate 40 in New Mexico and had to try to figure out what was going on.

Invest in your own scan tool. A decent one that you can hook up and just have it tell you what the problem is and maybe reset the code. I got a cheap one on Amazon and was able to reset the dam thing so i could keep moving to get home.
