So I have a 2021 silverado duramax lt z71, 6k miles.....I cranked the tension keys 7 full rotations to level the front(still have over an inch of room between control arm and bump stop)...35x12.50r22 with tpms(stock tires are taller by 1/4" easily, but skinnier)......I thought my rear tires were off balanced so I jacked the rear up and put the truck in drive, making sure there weren't broken belts in the tires. Visually inspected the rotation and all, went back to put the truck in park and turn off.......every light having to do with rear axle was on!! E-brake, traction control, etc....dripped the jack, turned truck back on for test drive and everything but check engine light WAS OFF, but pop ups saying service ESC on the info screen. Drove it about a mile or so, turning, accelerating etc. Now just the check engine light stays on.....will update when I can read the codes
