What Cummins code 13742 means

The ECM expected HVESP7 Module 12 Operational Status to arrive on the datalink at a regular rate and it is arriving late or not at all. This is a communication fault between modules (J1939 / J1587 wiring, terminating resistors, or a module that is powered down or not responding) rather than a sensor fault.

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 14116 FMI 9 rather than as Cummins code 13742. Cummins INSITE and Calterm show the Cummins number, the SPN / FMI pair and the lamp together.

J1939 failure mode identifiers (FMI)

FMI 9 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 13742

What does Cummins fault code 13742 mean?

Cummins 13742 is "HVESP7 Module 12 Operational Status - Abnormal Update Rate". It maps to SPN 14116 FMI 9. The ECM expected HVESP7 Module 12 Operational Status to arrive on the datalink at a regular rate and it is arriving late or not at all. This is a communication fault between modules (J1939 / J1587 wiring, terminating resistors, or a module that is powered down

Which lamp does fault code 13742 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 13742?

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 13742 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.
