This document describes the collection of IUMPR data required by the Heavy Duty On-Board Diagnostic regulation 13 CCR 1971.1 (l)(2.3.3), using SAE J1939-defined messages incorporated in a suite of software functions.

This Information Report is intended to supplement the J1939 documents by offering the application of SAE RP J1939 to OBD data communications in a form that can be sorted and searched for easier use. It is NOT intended as a substitute for the actual regulations and standards documents, and any discrepancies between this document and the published documents must be resolved in favor of the published documents. This spreadsheet outlines elements in ARB OBD II and HD OBD requirements and identifies which J1939 SPNs and messages may be used to satisfy the datastream, readiness, in-use ratio, and test results requirements.

The purpose of this SAE Recommended Practice is to verify that vehicles and/or components are capable of communicating a required set of information, which is described by the diagnostic messages specified in SAE J1939-73, that is in accordance with off-board diagnostic tool interface requirements contained in the government regulations cited below. This document describes the tests, methods, and results for verifying diagnostic communications from an off-board diagnostic tool (i.e., scan tool) to a vehicle and/or component. SAE members have generated this document to serve as a guide for testing vehicles for compliance with ARB and other requirements for emissions-related on-board diagnostic (OBD) functions for heavy-duty engines used in medium- and heavy-duty vehicles. The development of HD OBD regulations by U.S.

The purpose of this Recommended Practice is to verify that vehicles and/or components are capable of communicating a minimum subset of information, in accordance with the diagnostic test modes specified in SAE J1939-73: Diagnostic Services. This document describes the tests, test methods, and results for verifying diagnostics communication from an off board device to a vehicle and/or component.

This document describes the application of the SAE J1939 recommended practices for compliance with on-board diagnostic malfunction detection system requirements for marine sterndrive and inboard spark ignition engines, as mandated by the California Air Resources Board (CARB). These Otto-cycle engines are not derived from automotive diesel-cycle engines.

SAE J1939-13 specifies the diagnostic connectors used for off-board connection to a vehicle’s SAE J1939 communication links. The defined diagnostic connectors support connection to the twisted shielded pair media (SAE J1939-11), the Reduced Physical Layer unshielded twisted pair (SAE J1939-15), the unshielded twisted pair of SAE J1939-14, as well as the twisted unshielded quad media (ISO 11783-2).

These Recommended Practices are intended for light, medium, and heavy duty vehicles used on or off road as well as appropriate stationary applications which use vehicle derived components (e.g. generator sets). Vehicles of interest include, but are not limited to: on and off highway trucks and their trailers; construction equipment; and agricultural equipment and implements. The purpose of these Recommended Practices is to provide an open interconnect system for electronic systems. It is the intention of these Recommended Practices to allow Electronic Control Units to communicate with each other by providing a standard architecture.

This top level document describes the network in general, the OSI layering structure, the subordinate document structure, and provides control for all preassigned values and names. The Appendices of this document lists all SPN assignments, PGN assignments, NAME Function assignments, Manufacturer Code assignments, and Preferred Address assignments. All SPN and PGN assignments are listed in this document even though the complete definition details might be recorded in another standard. The SPN and PGN listings in this document identify the standard document that either contains the definition details or is associated with the identifier.
