## Abstract

Today's action finalizes modifications to EPA's Service Information regulations for light-duty vehicles and trucks, including requiring Original Equipment Manufacturers (OEMs) to: make full text emissions-related service information and training information available via the World Wide Web; provide equipment and tool companies with information that allows them to develop equipment with pass- through reprogramming capabilities; make available enhanced diagnostic information to equipment and tool companies; make available OEM- specific diagnostic tools for sale to interested parties and; make available additional OBD technical information that OEMs must provide. In addition, today's final rule extends the availability of emission- related service information to heavy-duty engines and vehicles weighing 14,000 pounds or less beginning in the 2005 model year.
