Proposed rule, notice of document availability.


On June 8, 2001, the U.S. Environmental Protection Agency (EPA) published a Notice of Proposed Rulemaking (66 FR 30830) proposing revisions to regulations requiring availability of information for use of on-board diagnostic systems (OBD) and emission-related repairs. One of the proposed changes specified that manufacturers comply with SAE Standardized Practice J2534 for “pass-through reprogramming” for MY 2003 and later OBD-equipped vehicles with reprogramming capabilities. At the time the proposal was issued in June 2001, SAE J2534 had not yet been finalized. In the proposal, EPA committed to issuing a notice of document availability in the Federal Register to announce that SAE J2534 had been finalized.

SAE J2534 was finalized in February of 2002 and is now available for inspection only in EPA Air Docket A-2000-49 (see ADDRESSES). In addition, interested parties can purchase this document directly from the Society of Automotive Engineers (SAE) (see ADDRESSES).


Materials relevant to this rulemaking are contained in Docket No. A-2000-49. The docket is located at The Air Docket, 401 M. Street, SW., Washington, DC 20460, and may be viewed in room M1500 between 8 a.m. and 5:30 p.m., Monday through Friday. The telephone number is (202) 260-7549 and the facsimile number is (202) 260-4400 and the Internet e-mail is A reasonable fee may be charged by EPA for copying docket material.

SAE J2534 can be purchased from the Society of Automotive Engineers (SAE), 400 Commonwealth Drive, Warrendale, PA 15096-0001 or at
