What is CAN SAE J1939?
The SAE J1939 network protocol describes communication on a CAN bus in commercial vehicles for transmitting diagnostic data and control information. The protocol was defined by the international Society of Automotive Engineers (SAE) and operates on the physical layer with CAN high speed according to ISO 11898.
The focus of application is in the area of the drive train and chassis of commercial vehicles. The protocol is used in heavy vehicles for both road and off-road operation (agricultural and construction machinery).
