(06/05/03) Final revisions to EPA’s Service Information Rule will make vehicle repair information for passenger vehicles and heavy-duty trucks more accessible to service and repair technicians. All 1996 and newer passenger vehicles are required to have On-Board Diagnostic (OBD) systems. Under the revisions, all heavy-duty trucks beginning in 2005 will be required to have OBD systems. The system is designed to trigger a “check engine” light on the dashboard of a vehicle or truck if the various pollution control devices are not functioning properly. Today’s action will also improve the quality of the scan tools used to diagnose OBD-equipped vehicles. This rule will require that the repair information be readily available on the Internet. To effectively service OBD-equipped vehicles and trucks, independent auto technicians will have access to the same emissions-related repair information and in the same manner as the manufacturer’s franchised dealerships. Consumers will have more choices on where their vehicles will be serviced. For more information, go to: .
