The driver or input for EGR Valve Control Circuit sees more current than it should, which the ECM interprets as a short to ground: chafed insulation, a pinched harness, or a shorted coil / solenoid.
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 2791 FMI 6 rather than as Cummins code 2353; an OBD-II reader shows it as P0489. Cummins INSITE and Calterm show the Cummins number, the SPN / FMI pair and the lamp together.
This is an emissions-system code. If the component it refers to has been removed or unplugged (DPF, EGR, SCR / DEF or NOx sensor delete) the code will keep returning and the derate with it, however many times it is cleared, because the diagnostic is still enabled in the calibration. The lasting fix in that case is to disable the fault in the .xcal itself.
Fault code 2353 is defined in the fault tables of the Cummins calibrations we have analysed and is one of the more commonly enabled codes, so it is a real, current code rather than a legacy number.

J1939 failure mode identifiers (FMI)
FMI 6 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 2353
What does Cummins fault code 2353 mean?
Cummins 2353 is "EGR Valve Control Circuit - Current Above Normal or Grounded Circuit". It maps to SPN 2791 FMI 6 and OBD code P0489. The driver or input for EGR Valve Control Circuit sees more current than it should, which the ECM interprets as a short to ground: chafed insulation, a pinched harness, or a shorted coil / solenoid.
Which lamp does fault code 2353 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 2353?
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 2353 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.
