anti lock brakes and traction control lights on

I've encountered this before on my old Jetta as well as some of my friends' cars. Both of these systems work using a signal from wheel speed sensors that are generally mounted on or near the brakes. They're usually about the size of a roll of pennies. If they're gooped up, bent out of alignment, unplugged or the wires are damaged they will send a "no-spin" signal to the computer, telling it to activate the ABS (that pulsing you're feeling in the brake pedal) as well as cause all sorts of errors in the traction control module. That seems to be the most likely source of failure.

Buy a gm part #22715444 replace it it will fix the problem

There are so many possible answers for this question but the old turkey said it best get the codes read at your dealer and find out exactly whats wrong . If you happen to have access to a reader that does abs that will go a long way to helping you out but until then your only guessing. Ive replaced abs pumps with cars that have a traction control light on and Ive replaced sway bars as well changed wheel bearings abs sensors. brake pedal sensors and drive by wire gas pedal all for the same light. In some cars its the gyro that tell you when the car is leaning that screws up. Getting the codes read is your best option
