Brakes and rotors replaced but i cant understand why the lights stayed on
I had my front hub bearings replaced, if bearings go bad then it throws off the sensors. If you hear a humming while driving and increases as you accelerate then it's the hub bearings.
I Bearing hun does not work to fix, thentry then try the wie harness
start with driver sidefirst
IF bearing hub does not work to fix then try the wire harness replacement, order at autoparts center start with driver side first

Sounds like you have a bad wheel speed sensor. You need to have it scanned. Since it's been sitting, it might just be a bad connection to one of the speed sensors.

I have this same problem with my 2000 Grand Am and the mechanic that I had taken it to had told me it was from a bad ABS sensor in a wheel hub, in order to fix that I would need to purchase a new hub. He said that triggered the service vehicle soon light and had caused the ABS light to come on as well. Although I have not fixed it yet, I trust that this is the problem.

This is the TCS or Traction Control System. It helps keep the vehicle from being able to get stuck by forcing the torque to either tire. Usually there is a switch either on the dash or on the shifter that says TCS or TRAC press the switch and it should go off.

you will need a scan tool to properly diagnose this problem accurately.but i can tell you that the most common problem is wheel speed sensors and or their wiring.
