  • Parameter Group Number represents the identifier of a J1939 message.
  • Every J1939 message has a unique PGN assigned to it by the SAE committee when the message is defined.
  • A PGN is 18-bits wide and is made up of the following fields:
  • Extended Data Page, Data Page, PDU Format
  • Depending on the value of the PDU Format field, a message is either destination-specific, meaning it is for a specific node.
