This document defines a physical layer having a higher bandwidth capacity than other physical layers defined for SAE J1939. Newer transceiver technologies are utilized to minimize EMI. CAN controllers are now available which support the flexible data rate frame format. These controllers, when used on SAE J1939-14 networks, must be restricted to use only the classical frame format compliant to ISO 11898-1:2015. This SAE Recommended Practice is 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.
