Looking for a simple intro to J1939? In this video we go through the basics, applications, PGNs, SPNs and more.

SAE J1939 is the standard communications network for ECUs within commercial vehicles. This includes in particular heavy duty applications such as trucks, buses, foresting, mining, agriculture etc.

J1939 is a higher layer protocol based on CAN bus and specifies e.g. how to handle multi-packet messages - and how to interpret raw data. In particular, J1939 defines standard Parameter Group Numbers (PGNs) and Suspect Parameter Numbers (SPNs).

Armed with a J1939 data logger and the J1939-71 standard, one is able to go from raw J1939 CAN bus data to scaled engineering values on e.g. vehicle speed, RPM and more.

In this intro, we run through the basics of the SAE J1939 standard incl. applications, message interpretation and considerations when choosing a J1939 data logger or J1939 interface. We also briefly touch upon J1939 DBC files, the J1939 request message and J1939 multi packet messages.
