Under the provisions of OBD-II regulations, emissions related diagnostic and service information will be readily available to the service industry, from the vehicle manufacturer. This information includes procedures and specifications necessary to diagnose the engine control system. Although enhanced diagnostics may be available using special equipment and procedures, at a minimum, repair procedures will be written using the generic scan tool and other commonly available test equipment like multimeters; and oscilloscopes.
In an effort to simplify diagnostics, OBD-II requires that all manufacturers standardize DTCs on OBD-II equipped vehicles. Eventually, all emissions related service information will be standardized in format and available through an electronic media.
