Detroit SPN 3711 EPA10 is a Detroit DD Series diagnostic trouble code (DTC) that reports that a High Idle Regeneration (HIR) was aborted because the Diesel Oxidation Catalyst (DOC) inlet temperature did not reach the 270°C (518°F) minimum needed to begin dosing during an HIR. This library entry summarizes the official one-page EPA10/GHG14 fault-code sheet published on TruckFaultCodes.com (Copyright © 2017) so technicians can confirm the meaning of the code before opening the full PDF.

Detroit SPN 3711 EPA10 description and steps
The Detroit SPN 3711 EPA10 sheet describes the fault as “High Idle Regeneration (HIR) Aborted – Low Exhaust Temperature” and lays out the diagnostic path Detroit expects a technician to follow. Key points from the document:
- Connect the diesel diagnostic tool and check whether SPN 3242 FMI 8 or SPN 3242 FMI 20 is active; troubleshoot those first.
- Monitor the DOC inlet and outlet temperature sensors while idling for 10 minutes, and replace the DOC inlet sensor if its reading has drifted low.
- Perform an Intake Throttle Service Routine and replace the Intake Throttle Valve (ITV) if the commanded position is not achieved.
- Inspect the exhaust and intake tract for leaks, check Inlet Manifold Pressure during a parked regen, and verify Jake Brake® operation and oil temperature.
- Review Actual Fuel Mass (AS087) during the regen and send the log file to the Detroit™ Customer Support Center if further analysis is needed.
Applicable truck models
This fault-code sheet applies to Detroit DD Series engines (DD13, DD15 and DD16) built to EPA 2007 and later emissions standards, and to Series 60 engines with DDEC VI (EPA 2007). Coverage and calibration always depend on the specific chassis and engine build, so verify applicability against the vehicle before servicing.
