Cummins fault code 3714 is logged by the electronic control module (ECM) on Cummins ISX11.9 and ISX15 CM2250 engines when it detects a engine protection torque derate problem recorded as Engine Protection Torque Derate – Condition Exists. This page in the DiagTechPro manuals library explains the SPN, FMI and lamp behaviour so a technician can plan the repair before the truck reaches the bay. Every entry in this library follows the same layout, so a workshop can move quickly from the dashboard warning to the correct wiring or component test.
What Cummins fault code 3714 means
Cummins identifies this event as SPN 1569, FMI 31, with an amber warning lamp. The ECM illuminates the amber CHECK ENGINE lamp and applies an immediate engine power derate.
How the ECM sets this code
This is an information-only code showing that the ECM has commanded an engine power derate so the critical fault codes that are presently active are addressed as quickly as possible. Reading the exact SPN and FMI with a Cummins INSITE electronic service tool is the fastest way to confirm you are chasing the right circuit rather than a related aftertreatment code.
Possible causes and shop talk
Because it is informational, this code goes inactive on its own once the underlying critical fault codes are found and repaired, so start by reading and clearing those active codes. This entry behaves as an informational status rather than a hard component failure, so read every active code with INSITE and work the highest-priority faults first.
Clearing fault code 3714
Because fault code 3714 can share root causes with other SPN 1569 aftertreatment and engine codes, repair the confirmed fault, then restore the monitored conditions and check that the status changes to inactive in INSITE.
