The standard maps functions to specific termed Diagnostic Messages (DMs). Technicians and developers interact with these primary messages daily: DM1: Active Diagnostic Trouble Codes (PGN 65226)

– If you have more context about what the PDF was supposed to cover (e.g., diagnostic trouble codes, PGNs, SPNs), I can point you to the correct standard.

Instead of the "P0420" codes found in passenger cars (OBD-II), J1939-73 uses a four-part structure:

This identifies the specific component or system that is malfunctioning (e.g., SPN 190 is Engine Speed).

While protocols like Unified Diagnostic Services (UDS/ISO 14229) operate on a request-and-response loop optimized for passenger vehicles, SAE J1939-73 uses a built over a 29-bit CAN identifier structure. This design allows ECUs to transmit active vehicle diagnostics continuously, enabling real-time fault tracking without flooding the network with request packets. sae j193973 pdf exclusive
