Three wheel speed sensors. One at each front wheel and one in the rear differential housing. You can drive with the light on. The Anti-Lock Brake Computer detected a problem, set a diagnostic fault code, turned the system off, and turned the light on to tell you. The ABS system is added on to the base brake system. You still have that base brake system when the ABS option is disabled.
