06 tahoe z71 "service stability"
 

Hey, i just did rear brakes on a tahoe, and about a mile up the road the service stability light came on. I did pads and turned the rotors, but didnt touch the emergency brake system. I also did an idler arm, pitman arm, and an inner tie rod, but i dont think that has anything to do with it. I read up on the issue and its either the yaw rate sensor under the pass. side seat, or something to do with the brake assisted traction control. I'm assuming its the latter, but i dont know what i could have done to make the light come on. Is there a special step you're supposed to do when you do rear brakes? any input is appreciated. :o

Is the ABS warning indicator on? A major component of the stability control system is the ABS. In any case, there should be one or more codes (probably not powertrain, more likely chassis) that can help shed a light.

double check you didn't pinch or cut an ABS sensor wire otherwise as einst said you'll need the codes
