Service Stabilitrak? on 13 Tahoe

[tstar2028]

Greetings, So I cranked up the truck and had these two messages pop up out of nowhere! I do not have any engine problems! They're still on when driving. Everything seems normal braking wise, no CEL, I tried to look up the solutions and got mixed feedback. Some said brake light sensor, MAF sensor, misfiring etc. I have noticed a slight roughness on idle but that's about it! I have a code reader, and nothing came up.

you need a scanner that can read body codes, otherwise it's a guessing game unless you find something broken or did something to it. like lifted it, lowered it, changed shocks, etc...
most commonly it is suspension related, check that first before presuming the worst (transmission)

How many miles? Any recent modifications?

How many miles? Any recent modifications?

185K and no everything is factory!

I have the same thing going on. Can find nothing wrong. It drives great.

It was the steering position sensor on mine.

As stated above, you need a bi-directional scanner, not a simple code reader. If you have dash warning lights, there IS absolutely a code (or more) available to view and understand, if you have a bi-directional scanner. If you do any significant wrenching on your truck, then you can save literally thousands of dollars over the life of the truck, by owning a bi-directional scanner.

If you did any modding of the rear suspension, check the top of the truck's frame over the rear wheels near the top of the shock, and look for an electrical wire with a connector. That connector often comes apart by accident, when working in that area, particularly if you work on the shock's upper bolt.

Okay I just went to autozone and used their scanner it says C0050-00 Right Rear Wheel Speed Sensor Circuit

check the wire harness to the sensor, if it looks ok then replace the sensor
not sure if you can swap left & right sensors on the rear but if you can you could try that as well to confirm if the problem follows the sensor.

That is the same circuit/wire that I mentioned about there being a connector sitting on top of the truck's frame over the rear wheels.
