I have a 2002 Grand Am 3.4L with 100,000 km. While driving the other day the service engine soon light and the ABS light and the Trac light all came on at once with the audilble alarm sounding. Every now and then I can get the lights to go off by turning the ignition key off and restarting. I tried retrieving codes with my Mac ProCode OBD II code reader but there are no codes coming up. It displays PASS as if no codes were detected yet the 3 lights are all on.
Any suggestions?

Typically when the 3 lights come on, it most often turns out to be a front wheel speed sensor that usually comes with the bearing/hub.
