Cummins fault code 3714
Engine Protection Torque Derate: condition exists
What it means
Cummins' description: Engine Protection Torque Derate - Condition Exists.
SPN 1569 is Engine Protection Torque Derate. FMI 31 means the ECM has confirmed the condition described in the code is happening.
Engine protection codes mean the ECM has reduced power or is preparing to shut down to protect the engine. The protection is triggered by another problem, so look at the other active codes to find the real cause.
What the lamp means
An amber (yellow) warning lamp means the engine can usually keep running, but the fault should be repaired soon, ideally the same day.
Green, yellow, red: three ways this can look
The same code can be a quick fix or a reason to shut down. Match your situation to the closest example.
Keep an eye on it
A brief derate that cleared once the engine cooled on a steep climb in heat.
Schedule a repair
Derate comes and goes, or happens with other aftertreatment codes. Diagnose the code underneath before it becomes a shutdown.
Stop and get help
Approaching shutdown warning, stop lamp, or a severe derate. Pull over safely now. The engine is protecting itself from damage.
Common causes
The sensor reading itself is out of range or the condition is real, so look at the system:
- High coolant or oil temperature
- Low oil pressure or coolant level
- Aftertreatment problem (DPF, DEF, SCR)
- Overspeed or high altitude
- External protection input from equipment
What you can check before calling
- Look for other active codes. They tell you why protection kicked in
- Check coolant and oil levels and the gauges
- Note what the truck was doing when power dropped
Clearing the code without fixing the cause usually brings it right back, and on emissions systems it can restart derate timers.
