2004 Chevy Cavalier LS. Service w/ wrench, ABS, No Traction lights. Replaced brake pads replaced over a year ago.
My service, ABS and No trac lights are all coming on intermittently, but at the same time. They go off when I turn off the car and restart it. They come on when I am in the middle of driving or sometimes when I put it into reverse and back in to drive. There is also a noise when I make left hand turns.
The light with the wrench is the "Service Vehicle" light. These lights are most likely all related. Sounds as if you have a problem in the ABS system. A problem in the ABS will cause the ABS light to come on, traction control system will be disabled, and the service vehicle light will come on. The ABS computer will have to scanned for codes. By what you describe, most likely have a front wheel speed sensor problem, or the harness going to one of the front speed sensors has a broken wire inside the insulation, or full of water.
