Data in Table A5B reflects the content of SAE J1939-DA of February 2015. Section A.10 was added to describe processing for PGNs that are only supported by some of the OBD modules under test.

Streaming Processes for Heavy-Duty Vehicles

Heavy-duty engine design Increasing regulations and market demands call for cleaner, more durable and fuel-efficient engines. Developers rely on CAE simulation, enhanced test methods and 3D printing to keep up. Switching to comfort mode Switches, knobs and touch panels evolve to reduce operator fatigue. Big on prognostics Smart data-analyzing procedures that support predictive maintenance will help to significantly increase the uptime of heavy-duty vehicles. The "Evolution of Big Data" symposium at SAE COMVEC 2018 addresses such critical topics. Starship road trip Optimized aerodynamics and production-ready technologies propel Shell's Class 8 concept to a 248% freight-ton-efficiency improvement.

The SAE J1939DA Digital Annex spreadsheet replaces the Appendices of this document for the publication of the list of all SPN assignments, PGN assignments, NAME Function assignments, Manufacturer Code assignments, and Preferred Address assignments. ...This document has been updated to reflect the change to discontinue publishing the content of Table A2, Tables B1 through B12, and Table C1 in Appendix A, Appendix B, and Appendix C; instead, this content is now published in the SAE J1939DA Digital Annex spreadsheet.

The SAE J1939 communications network is developed for use in heavy-duty environments and suitable for horizontally integrated vehicle industries. The SAE J1939 communications network is applicable for light-duty, medium-duty, and heavy duty vehicles used on-road or off-road, and for appropriate stationary applications which use vehicle derived components (e.g., generator sets). Vehicles of interest include, but are not limited to, on-highway and off-highway trucks and their trailers, construction equipment, and agricultural equipment and implements.SAE J1939-71 is the SAE J1939 reference document for the conventions and notations used to specify the parameter (SP) placement in PG data, the conventions for ASCII parameters, and conventions for PG transmission rates. This document previously contained the majority of the SAE J1939 OSI application layer data parameters and messages for information exchange between the ECU applications connected to the SAE J1939 communications network.

The data parameters (SPNs) and messages (PGNs) previously published within this document are now published in SAE J1939DA. The reference figures and reference information for the SPNs and PGNs associated with the SAE J1939-71 document are published in this document.
