What Cummins code 17335 means

The value of Fuel Cell Stack Water Pump is changing faster or slower than is physically plausible, so the ECM treats the reading as suspect. Often a loose connector, a failing sensor, or a mechanical problem the sensor is faithfully reporting.

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 517041 FMI 10 rather than as Cummins code 17335. Cummins INSITE and Calterm show the Cummins number, the SPN / FMI pair and the lamp together.

J1939 failure mode identifiers (FMI)

FMI 10 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 17335

What does Cummins fault code 17335 mean?

Cummins 17335 is "Fuel Cell Stack Water Pump - Abnormal Rate of Change". It maps to SPN 517041 FMI 10. The value of Fuel Cell Stack Water Pump is changing faster or slower than is physically plausible, so the ECM treats the reading as suspect. Often a loose connector, a failing sensor, or a mechanical problem the sensor is faithfully reporting.

Which lamp does fault code 17335 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 17335?

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 17335 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.
