My warning light comes on saying: Service Traction Control, it blinks and I see that the ABS light is on as well. They all are in one together, not separate! They all come on together at the same time. I have not noticed any difference in driving the vehicle, just notice the lights on. I had new brakes put in so it cannot be bad brakes and they have been checked. It seems to come on whenever the tires are rotated, I get new tires or I put air in the tires.
