The National OBD Clearinghouse is a website established by the Center which receives funding from the EPA and OBD technical information from automotive manufacturers to help support state Inspection & Maintenance (I/M) programs across the country. Some of the main functions of the Clearinghouse include: design and upkeep of the National OBD Clearinghouse website; collecting information from vehicle manufacturers and their service websites such as Technical Service Bulletins (TSBs), Data Link Connector (DLC) locations, and communication protocols; offering a member forum on the website where state I/M administrators can discuss current topics with other states and vehicle manufacturer representatives; providing updated contact information for every states I/M programs; and posting other relevant EPA and state documents on the website.
Apart from state I/M administrators, the OBD Clearinghouse also strives to benefit individual inspection facilities and the manufacturers themselves. While not all of the information is available to them, many inspection and repair shops use the website to look up vehicle documents and other information. Vehicle manufacturers benefit from the Clearinghouse by having a resource they can use to address problems and answer questions once, not having to contact each I/M program or give the same answer a number of times with states contacting them to resolve common issues. Since the National OBD Clearinghouse has been created, commination between state I/M programs, vehicle manufacturers, and the EPA has been easier and more effective.
