The Environmental Protection Agency (EPA) has extended the public comment period on a proposed rulemaking that applies to use of on-board truck diagnostic systems and emission-related truck repairs, according to information published August 6 in the Federal Register. The proposal refers to 1994 late-model year light-duty trucks and 2005 and later-model year for heavy-duty vehicles and engines weighing 14,000 pounds gross vehicle weight or less. The comment period has been extended to August 27, 2001.
If approved the rule would require vehicle manufacturers to make full text emissions-related service information and training information available via the World Wide Web and provide equipment and tool companies with information that allows them to develop equipment with pass-through reprogramming capabilities. It would also require manufacturers to make available enhanced diagnostic information to aftermarket scan tool manufacturers. In addition, the proposal calls for manufacturers to make specific diagnostic tools for sale to interested parties and make available additional on-board diagnostics technical information that manufacturers must provide.
The proposal requests comment on extending 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, according to the Federal Register information.
