INTEGRATING ON-BOARD DIAGNOSTIC SYSTEM CAPABILITIES INTO THE INSPECTION AND REPAIR FUNCTIONS OF I/M PROGRAMS
At any point in time, a certain percentage of motor vehicles on the road are emitting in excess of their design standards due to repairable causes. Motor vehicle emissions inspection and maintenance (I/M) programs employ a short screening test to identify high emitters and a retest after repairs to confirm their effectiveness in reducing emissions. It is the initial screening test and the retest after repairs that differentiate I/M from a public information campaign about motor vehicle maintenance or from a program to train automotive mechanics. This report describes the capability of the newer motor vehicles to perform self-diagnosis, and how these capabilities could be integrated into both the inspection function and the repair function. Specific recommendations to the I/M programs are also included.
