A smart device or component involved with EACS PDM CLASS1 FAIL GRADE has failed its own internal test or is returning data the ECM considers invalid. For ECM internal faults the usual outcome is an ECM replacement or re-flash; for external smart sensors it is normally the sensor.
It lights the amber CHECK ENGINE (warning) lamp. The engine keeps running, but a torque or speed derate may apply depending on the calibration and on how long the fault stays active.
On a generic J1939 scan tool, or on the dash of a Freightliner, Kenworth, Peterbilt, International or Volvo chassis, the same fault is shown as SPN 516210 FMI 12 rather than as Cummins code 13639. Cummins INSITE and Calterm show the Cummins number, the SPN / FMI pair and the lamp together.

J1939 failure mode identifiers (FMI)
FMI 12 is highlighted. The FMI is the second half of every J1939 fault and tells you how the component failed; the SPN tells you which component.

Questions about code 13639
What does Cummins fault code 13639 mean?
Cummins 13639 is "EACS PDM CLASS1 FAIL GRADE - Bad Intelligent Device or Component". It maps to SPN 516210 FMI 12. A smart device or component involved with EACS PDM CLASS1 FAIL GRADE has failed its own internal test or is returning data the ECM considers invalid. For ECM internal faults the usual outcome is an ECM replacement or re-flash; for external smart sensors it is
Which lamp does fault code 13639 turn on?
Amber WARNING lamp: It lights the amber CHECK ENGINE (warning) lamp. The engine keeps running, but a torque or speed derate may apply depending on the calibration and on how long the fault stays active.
How do I clear or permanently delete Cummins code 13639?
An active code goes inactive on its own once the condition is gone; the inactive record stays in the ECM fault history until it is cleared with Cummins INSITE (or a J1939 tool that supports the DM3 / DM11 clear). If the code keeps coming back because the part is gone, disconnected or not worth repairing, the lasting fix is to disable fault 13639 in the calibration: upload your .xcal to the ECFG Superstore file service, custom DTC delete from $150 (up to 30 codes), full DPF / EGR / SCR delete $500, and flash the returned file with Calterm or INSITE.
