The Board's Action. At its April 25, 2002,
public hearing, the Air Resources Board (the "Board" or "ARB") approved the
adoption of sections 1968.2 and 1968.5, title 13, California Code of Regulations
(CCR). Upon becoming operative, section 1968.2 would establish OBD II
requirements for 2004 and subsequent model year vehicles; section 1968.5 would
establish an OBD II-specific in-use enforcement protocol.
At the
hearing, the Board adopted Resolution 02-17 (appended to this notice as
Attachment I), approving the proposed regulations with modifications. In
approving the proposed regulations, the Board specifically included staff's
suggested modifications to the initially noticed text, which were made available
at the hearing. The suggested modifications were appended to the Resolution as
Attachment B. In the Resolution, the Board directed the Executive Officer to
incorporate the approved modifications into the proposed regulatory text, along
with such other conforming modifications as may be appropriate, and to make such
modifications available for a supplemental comment period of at least 15 days.
Modified Text Being Made Available. The regulations, as modified, are
appended to this notice as Attachments II (section 1968.2) and III (section
1968.5). Additions to the text are denoted by underline and deletions by
strikeout. In Attachment IV to this notice, staff explains and provides
rationale for the proposed substantive modifications to the text. Within
Attachment IV, the staff specifically identifies those substantive modifications
that have been made since the April 25 hearing. In addition to the modifications
detailed in Attachment IV, staff has made other minor modifications throughout
sections 1968.2 and 1968.5 of title 13 to improve clarity and to correct
citations and references.
Attachments I through IV may be obtained off
the Internet at the address

the ARB Mobile Source Control Division, at (626) 575-6615, or by faxing or
mailing the request form attached to the end of this notice to the address or
number detailed on the form.
Supporting Documents and Information. In
accordance with Government Code section 11347.1, the staff has added to the
rulemaking record the following document, which is incorporated by reference in
the regulations, as modified:
SAE J1939 APR00-"Recommended Practice for
a Serial Control and Communications Vehicle Network" and the associated subparts
included in SAE HS-1939, "Truck and Bus Control and Communications Network
Standards Manual", 2001 Edition (SAE J1939).
Staff has also corrected the
name of the following document, which is incorporated by reference into section
1968.5, and was included in the original rulemaking record under an abbreviated
document title.
EMFAC2000 "Public Meeting to Consider Approval of
Revisions to the State's On-Road Motor Vehicle Emissions Inventory: Technical
Support Document, Section 7.1, 'Estimation of Average Mileage Accrual Rates from
Smog Check Data,'" May 2000.
Staff has also added the following
additional document that supports the proposed action:
ARB Study of
Current OBD II Monitoring Frequency (In-Use Testing Data)
Additionally,
within the modified regulatory text, staff has revised and updated the titles
and publication dates of several Society of Automotive Engineers (SAE) and
International Organization of Standards (ISO) documents, which are incorporated
by reference into section 1968.2. The changes reflect the recent decision of the
two organizations to harmonize and jointly publish several of their
publications. While the changes to the title for most of the incorporated
documents is relatively insignificant, the publication change has necessitated
deleting ISO 15031-5 from the text of 1968.2 and replacing it with the most
recent version of SAE J1979, the full title of which is set forth below. The
modified titles and latest publication dates of the documents that have been
previously noticed as being incorporated by reference are:
1) SAE J1930
"Electrical/Electronic Systems Diagnostic Terms, Definitions, Abbreviations, and
Acronyms - Equivalent to ISO/TR 15031-2:April 30, 2002", April 2002.
2) SAE
J1962 "Diagnostic Connector - Equivalent to ISO/DIS 15031-3:December 14, 2001",
April 2002.
3) SAE J1978 "OBD II Scan Tool - Equivalent to ISO/DIS
15031-4:December 14, 2001", April 2002.
4) SAE J1979 "E/E Diagnostic Test
Modes - Equivalent to ISO/DIS 15031-5:April 30, 2002", April 2002.
5) SAE
J1850 "Class B Data Communications Network Interface", May 2001.
6) SAE J2012
"Diagnostic Trouble Code Definitions - Equivalent to ISO/DIS 15031-6:April 30,
2002", April 2002.
7) ISO 9141-2:1994 "Road Vehicles-Diagnostic Systems-CARB
Requirements for Interchange of Digital Information", February 1994.
8) ISO
14230-4:2000 "Road Vehicles-Diagnostic Systems-KWP 2000 Requirements for
Emission-related Systems", June 2000.
9) ISO 15765-4:2001 "Road
Vehicles-Diagnostics on Controller Area Network (CAN) - Part 4: Requirements for
emission-related systems", December 2001.
