J1939 Considerations
J1939 is a CAN standard adopted primarily by the truck industry. It further specifies the Data Frame of
CAN’s Extended Format. In addition, a large number of parameters, typically known as Parameter Group
Numbers (PGNs) are specified. For ease of operation, a database of several hundred J1939 PGNs is
included with the DBK70 software.
Note: For J1939 only, the address of the DBK70 (diagnostic tool) is always F8.
If your vehicle under test supports J1939, use the included database to specify desired PGNs. The following
diagram shows how PGNs, per the J1939 standard, are formatted in the DBK70 database. The following is
an example of how to develop a DBK70 database record from the J1939 PGN, “Actual engine percent
torque”.
