Scope
The J1939 Digital Annex
The J1939 Digital Annex, introduced in August 2013, offers key J1939 technical data in an Electronic Spreadsheet that can be easily searched, sorted, and adapted to other formats. J1939DA contains all of the SPNs (parameters), PGNs (messages), and other J1939 data previously published in the SAE J1939 top level document. J1939DA also contains all of the SLOTs, Manufacturer ID Codes, NAME Functions, and Preferred Addresses previously published in the SAE J1939 top level and the J1939-71 document. J1939DA contains the complete technical details for all of the SPNs and PGNs previously published in the SAE J1939-71 document. It also includes the supporting descriptions and figures previously published in the SAE J1939-71 document. For other SPNs and PGNs which are published in a document other than SAE J1939-71, J1939DA lists only basic details along with a reference to the document that contains the complete technical details.
J1939DA replaces, and expands upon, the 1939 Companion Spreadsheet (CS1939), which was last published through November 2012.

Issuing Committee
Truck Bus Control and Communications Network Committee
The Truck and Bus Control and Communications Network Committee of the Truck & Bus Electrical/Electronic Steering Committee is responsible for developing, reviewing and approving standards, recommended practices and information reports related to communication networks for the exchange of control and diagnostic information among electronic components on or connected to truck and bus vehicles. The objective is the architecture of communication networks offering an open interconnect system that supports communication between loose package components, such as engines and transmissions, which are sourced from many different component suppliers and integrated into vehicle systems. The communication networks are developed for use in on-highway and off-highway trucks and their trailers, buses, construction equipment, and agricultural equipment and implements, and applicable to 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).
