Traction control light

If you checked with a code reader, you were just checking powertrain faults. You should however, have ABS fault codes. You can get these through an on-board feature that your vehicle has. At key on, if you press info up, and on/off at the same time, all the segments will light up. After the segment check, you will see ALL? On the info center. Use the info button to navigate to ABS, and press on/off, it will say ABS CODES, press on/off again and record the codes. I would suspect a wheel speed sensor, the problem with the published diagnostics is it groups all the codes for wheel speed sensors together, and there is no differentiation of which wheels sensor set the code. Reply with codes, and I will do the best I can, it may not be wheel speed sensor.
