J1939 Explained - A Simple Intro [v2.0 | 2021] 🌟

What is J1939? https://www.csselectronics.com/pages/... In short, J1939 is a set of standards defined by SAE (Society of Automotive Engineers) that define how electronic control units (ECUs) communicate via the CAN bus in heavy-duty vehicles. It is a higher layer protocol and serves as a standard for e.g. trucks, buses, excavators, tractors - across different manufacturers and brands. Further, J1939 serves as the basis for derived protocols like NMEA 2000 (maritime) and ISOBUS (agriculture). Within J1939, a 250K or 500K bit rate is used and 29-bit extended CAN frame identifiers (CAN 2.0B). CAN signals are called Suspect Parameter Numbers (SPN) and are grouped by their Parameter Group Number (PGN) within CAN frames. Because of the standardized nature of J1939, it enables both manufacturers (OEMs) and after market users to record as well as interpret raw data from heavy duty vehicles using e.g. CAN bus data loggers.
