The remains one of the most highly searched, "hot" topics among heavy-duty vehicle engineers, fleet managers, and telematics developers. As the Vehicle Application Layer of the broader SAE J1939 standards collection, this extensive protocol defines how raw Electronic Control Unit (ECU) data is translated into real-world parameter values like vehicle speed, engine oil temperature, and fuel economy.

SAE J1939-71 is a recommended practice developed by SAE International that defines the of the J1939 network architecture. While other parts of the standard (like J1939-11 or J1939-15) define physical cabling and J1939-21 defines the data link layer, J1939-71 specifies the actual Parameter Groups (PGs) and Suspect Parameter Numbers (SPNs) .
