Detroit SPN 3716 EPA10 is a Detroit DD Series diagnostic trouble code (DTC) that reports that a High Idle Regeneration (HIR) was aborted because coolant temperature did not reach the 140°F minimum needed to start 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.
On Detroit DD Series engines each fault is reported as a suspect parameter number (SPN) with a failure mode identifier (FMI): 3716 identifies the affected system and 31 describes how it failed. Read the pair with a diesel diagnostic tool such as DiagnosticLink to confirm whether the code is active or previously active before starting any repair.

Detroit SPN 3716 EPA10 description and steps
The Detroit SPN 3716 EPA10 sheet describes the fault as “High Idle Regeneration (HIR) Aborted – Low Coolant Temperature” and lays out the diagnostic path Detroit expects a technician to follow. Key points from the document:
- The Amber Warning Lamp (AWL) comes on for about 15 seconds during the regeneration, then goes out as the regeneration aborts.
- If the engine fails to reach 140°F, refer to the “Low Engine Coolant Temperature” procedure.
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. For engine specifications and warranty details, see the Detroit Diesel official website.
