check your wheel speed sensors. One of the wires may be disconnected or broken.
I have a 2000 venture and the traction control light came on. Where do I look first, hubs. Wiring.
Get your wheels checked
after fixing the whatever abs problems or traction control problems you had the light should go off automatically. if it does not you have not fixed the problem.
go have your car serviced at the dealership. they can fix it.
It means that the engine computer has detected a malfunction that will affect the emissions of the vehicle.
On my 2000 model focus, when the light is on permanently, this means the traction control has been turned off.
you cannot service panel lights on 2000 impala . you hav to replace the instrument cluster.
Low Traction
