It works! but Catch is the new VA-OBD II emission standards!!
Actually It worked for me too. However if your car make is after 1996, the new VA emission standards use DMV provided OBD II system that automatically checks & identify if there was any resetting or clearing of codes in the vehicle history just before inspections, that will trigger "NR" Not ready rating for those lights/components that were originally cleared or made it disappear and eventually they will NOT give pass certificate asking us to come back after driving more than 100 miles for retesting.
The catch is if we drive for those 100 miles or so or with regular day driving, the lights will eventually comeback should the problem persists or repairs not undertaken. So, to the extent of emission inspection, this lights clearing technic isn't very helpful but yes otherwise for those who doesn't want those lights annoy them.
