Check the hub assemblys when the traction control is engaged the computer does not allow full power to be distributed to the traction wheels should also check the rack and pinion either 1 of these issuses can cause problems with the steering and control of the vehicle also check the traction sensors

This light is usually caused by a problem in the ABS system. A problem in the ABS system will dissable the traction control system. you will need to have the computers scanned for trouble codes.

SOURCE: 2002 Chevy Impala Traction control /ABS problem
i have a 2002 chevrolet impala and the same thing happened to me. abs light came on as well as my traction controll light. when i would step on the gas or brakes my car sounded like the brake pads were skiping against my rotors. i had my hub sensor replaced 5 times. the machanic kept telling me it was the part that need to be replaced.they hooked it up to have a dianostic done and the computer keep telling them to replace the hub sensor. so finally we brought my car to an electric auto shop. they found it was a loose wire that was turning my brakes on and off.(haywire)they fix my car in 30mins.

verify all tire pressures are correct this can affect abs traction control on your vehicle
SOURCE: what would cause traction active light come on
i have had this problem since about 6 months after i bought my 2001 impala. the problem is in the hubs. the wireing that runs throw them rubs together and eventually shorts the traction and abs. easy solution to fix it though. get into the hubs and wrap the wires. otherwise take the car in and explain the problem to them and exactly what you need done. 9-10 times they won't fix the problem unless you tell them what you want done. it is really simple and going to the dealer should only cost you about 100 to fix.
