Description / Abstract:
Introduction
SAE J1939-03 provides requirements and guidelines for the
implementation of On Board Diagnostics (OBD) on heavy-duty vehicles
(HDV) using the SAE J1939 family of standards. The guidelines
identify where the necessary information to meet OBD regulations
may be found among the SAE J1939 document set. Key requirements are
identified here to insure the interoperability of OBD scan tools
across individual OBD compliant vehicles.
Market-defined regulations permit the use of SAE J1939 to meet
OBD requirements. Implementers are cautioned to obtain and review
the specific regulations for the markets where their products are
sold. This document is focused on guidelines and requirements to
satisfy the State of California Air Resources Board (ARB), the
authors of 13 CCR 1971.1, United States Environmental Protection
Agency, Euro IV and V requirements from European Commission
directives, and UN/ECE WP 29 GRPE WWH OBD Global Technical
Regulation (GTR)
