What does SPN 639 stand for in PACCAR MX?
With a CAN fault, there may be other modules setting related faults. SPN 639 is a CAN fault, so you may have a few modules with communications issues setting faults all related to that. SPN 513 is Actual Engine – Percent Torque.
Which is the engine SPN 513 or SPN 639?
The SA will tell you what module, SA: 0 is the engine. With a CAN fault, there may be other modules setting related faults. SPN 639 is a CAN fault, so you may have a few modules with communications issues setting faults all related to that. SPN 513 is Actual Engine – Percent Torque. I’m guessing it’s sensing low power or derated.

Do you need SPN number for PACCAR Engine?
It does log times in which the CELs happen which is another tool used to help diagnose. For SPN numbers to work, they require BOTH the SPN and FMI number. SPN numbers mean very little as they are not actual code numbers. Yes some SPN numbers can be converted to real code numbers but others do not compute.
What do the SA and FMI #’s Mean on PACCAR?
It is not a complete list though. If you are using the Paccar display to pull faults, there should be a SA and FMI #’s. The SA will tell you what module, SA: 0 is the engine. With a CAN fault, there may be other modules setting related faults.
