The ECM expected Longitudinal Acceleration 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.
No dash lamp is attached to this code in the Cummins fault table. It is logged in the ECM and shows up in Cummins INSITE (or any J1939 tool reading DM1 / DM2), but on its own it does not light a lamp.
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 1810 FMI 9 rather than as Cummins code 17366. 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 17366
What does Cummins fault code 17366 mean?
Cummins 17366 is "Longitudinal Acceleration - Abnormal Update Rate". It maps to SPN 1810 FMI 9. The ECM expected Longitudinal Acceleration 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
Which lamp does fault code 17366 turn on?
No lamp: No dash lamp is attached to this code in the Cummins fault table. It is logged in the ECM and shows up in Cummins INSITE (or any J1939 tool reading DM1 / DM2), but on its own it does not light a lamp.
How do I clear or permanently delete Cummins code 17366?
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 17366 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.
