Assuming the typo theory is correct, here is a comprehensive, useful article about the standard (most likely SAE J1939-73 ) and how to obtain an exclusive , legitimate PDF copy.
SAE J1939.73 is a subset of the SAE J1939 protocol, specifically defining the application layer for vehicle networks. The standard outlines the rules for data exchange between electronic control units (ECUs) in a vehicle network, enabling them to communicate with each other seamlessly.
