The Importance of OBD Testing for Vehicle Emission Control

OBD (On-Board Diagnostics) is a vehicle-mounted exhaust emission control device monitoring system. It can remind the owner of the relevant emission device of the vehicle in real time, so as to prompt the owner to repair it as soon as possible. In the annual vehicle inspection, OBD inspection is an important part. It uses the OBD diagnostic instrument to check whether the vehicle has relevant faults that affect emission control. In addition, the annual inspection also includes appearance inspection and emission testing. Only when these three inspections are passed can it be said that the vehicle has passed the annual inspection.
