System and method for testing vehicle emissions and engine controls using a self-service on-board diagnostics kiosk

A system and method for testing vehicle emissions and engine control components using a standalone self-service kiosk. The self-service kiosk includes a computer capable of gathering Vehicle Information (VIN) and OBD information from a vehicle being tested using a barcode reader and an OBD reader, respectively. The self-service kiosk generates a readable display or printed report to the user indicating any detected diagnostic trouble codes found during the vehicle emissions testing. By networking a plurality of self-service kiosks together in a secure network and accessible through the Internet, the self-service kiosk network maintains a centrally located vehicle information database for storing and retrieving pertinent vehicle-related information during vehicle emissions testing. If the vehicle being tested passes the vehicle emissions testing, then the self-service kiosk prints out a registration renewal sticker, registration renewal document and/or receipt for the user.
