ABS and Traction Control Light ON?

There are few basic,that are to be inspected to confirm why ABS and Trac control light coming up ON dashboard panel.

Most of the time this is due to either a faulty left or right wheel speed sensor, speed sensor tone ring or short in wiring harness, but may also be due to low tire pressure in one of the rear tires that cause the tires to spin at different rates.

First make sure the rear tires have same air pressure in each. If ok, then the ABS control module needs to be read with diagnostic scanner to retreive the fault code(s) in order to know which side the problem resides in and then the wheel speed sensor on the indicated side is tested and tone ring inspected for cracks, chips or breaks in it.
