ABS Light

On my 2004 Pontiac Grand Am SE1 4-Door: Randomly, the (ABS) light will come on along with the "Service Vehicle Soon" and "Trac Off" lights. The three lights will come on and stay on. Nothing else unusual going on. Car still runs and brakes fine. For now, I can clear the lights by stopping, shutting off the engine, and restarting. Any thoughts?

yes a wheel sensor or the harness connected to it. Unfortunately you either need a scan tool capable of telling you which sensor or you have to visually look for a bad connection and try a resistance test on each sensor.
