On this page, we provide two comprehensive technical presentations covering Classical CAN and SAE J1939.
The Classical CAN presentation introduces the fundamentals of CAN Bus communication, including the physical layer, message structure, arbitration, error detection, and other concepts essential to understanding how CAN networks operate.
The SAE J1939 presentation builds on these CAN Bus fundamentals and introduces the higher-layer protocol used extensively in commercial vehicles, heavy-duty equipment, agricultural machinery, and industrial applications. It covers essential J1939 concepts such as Parameter Group Numbers (PGNs), Suspect Parameter Numbers (SPNs), source addresses, network management, and message communication.
Both presentations are provided as free educational resources and can be used for self-study, technical reference, or training.
SAE J1939 Starter Kit and Network Simulator
The SAE J1939 starter kit is a powerful and versatile tool designed for monitoring, simulating, and recording any Parameter Group Number (PGN) specified in the SAE J1939-71 standard, including diagnostic messages as defined in SAE J1939-73.
Users frequently ask whether the kit can process specific parameters such as fuel consumption, vehicle speed, and position. The answer is always yes; however, the starter kit is not preconfigured for specific engine parameters. To access the desired data, you must identify the corresponding PGN.
Additionally, while the starter kit is not designed to simulate a particular diesel engine, it allows full customization. By inputting the necessary PGNs, you can create and simulate any diesel engine configuration. More Information…
