The Society of Automotive Engineers (SAE) J1939 standards define a communication protocol for networking and diagnostics among electronic control units (ECUs) in heavy-duty vehicles. With advancements in vehicle electronics and the need for higher data transmission rates, the SAE introduced updates to the J1939 standard to incorporate the capabilities of…

This time, we would like to introduce Version 4.01.00. We have listened to customer feedback suggesting that it would be helpful to select a PGN within the data stream and add it to the list of filtered PGNs. Consequently, we have added a corresponding command button. Please refer to page…
Modern vehicles have electronic control units (ECUs) to manage various subsystems, such as the engine, brakes, steering, air conditioning, and infotainment. These ECUs (or simply ‘controllers’) are networked together to share information and output both measured and calculated data directly to one another. The SAE J1939 in-vehicle network is a…
The SAE J1939-22 standard addresses the issue of limited bandwidth for future data-demanding applications when using Classical CAN as the hardware layer. The proposed solution is CAN FD, which enables larger data frames and higher transmission speeds. However, the originally envisioned backward compatibility has not been achieved. The Bandwidth Issue…
The JCOM1939 Monitor Software is the perfect tool for monitoring, recording, analyzing, and simulating SAE J1939 data traffic. It works in combination with our SAE J1939 gateways. This comprehensive, easy-to-use, and easy-to-understand Windows software displays SAE J1939 data traffic. It allows network scanning, simulating an ECU (including full node address…
What is the FMS Standard? At the turn of the 21st century, GPS-based vehicle tracking systems were becoming more affordable, yet they still lacked the capability to provide vehicle-related technical information. In a significant industry development, six leading truck manufacturers (Volvo, Scania, Iveco, MAN, DAF, Mercedes-Benz) joined forces in 2002…
