The OBDII computer monitors a vehicle’s emission control systems in real time and can inform a motorist or technician of a systemic issue the moment it occurs. The system operates through indicator lights, drive cycles, trouble codes, and readiness monitors. During an inspection, an emission analyzer scan tool plugs into the diagnostic connector attached to the OBDII computer and communicates with the vehicle. The OBDII computer relays to the scan tool whether it has discovered errors in the emission control systems. The emission analyzer then determines if the car is being operated according to emission standards.
