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 Vehicle Application Layer is the SAE J1939 reference document for the conventions and notations that specify parameter placement in PGN data fields, the conventions for ASCII parameters, and conventions for PGN transmission rates. This document previously contained the majority of the SAE J1939 data parameters and messages for information exchange between the ECU applications connected to the SAE J1939 communications network.

This document defines a physical layer having a robust immunity to EMI and physical properties suitable for harsh environments.

CAN controllers are available which support the CAN Flexible Data Rate Frame Format. These controllers, when used on SAE J1939-11 networks, must be restricted to use only the Classical Frame Format compliant to ISO 11898-1:2015.

These SAE Recommended Practices are intended for light- and heavy-duty vehicles 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.

SAE J1939-1 specifies the minimum set of SAE J1939 documents that define the Truck and bus control and communications vehicle network as it applies to on-highway equipment. Vehicles covered include all on-highway straight trucks and combination vehicles. A combination vehicle consists of one towing vehicle (tractor) and one or more towed vehicles (trailers and dollies). Dolly axles within the road train are considered to be towed vehicles.
