Service Traction Control and Stabilitrack?

[NASTY GM]

I rotated my tires and changed my rear shocks (to Belltech). Now I have Service Traction Control and Service Stabilitrack message. Also my ABS light is lit on my dash. I have rotated my tires and changed rear shocks before and this never happened. Any ideas?

not Tahoe/Yukon related, but I had the same problem in regards to the service stabilitrack message on my trailblazer. turns out it was a steering wheel position sensor

Dude you may have snagged the rear ABS sensors that coneect to the frame then wheel area, it tends to happen alot when people install lowering kits because they are careless when dropping the axle.
Are you sure you didn't snag them?
Also I had those codes pop up on me but they went away after like 15 minutes and the dealer said the car had just accidentally thrown a wrong code!

I got it. I went back under and found both plugs on top of the frame rail came undone. Plugged both back in and all is good!
