Scr torque derate.

Engine derate is an automatic safety feature that reduces the power output of a diesel engine to prevent damage and prolong its lifespan. This occurs when the engine control unit (ECU) detects issues such as emission system faults, high intake air temperature, or low DEF levels, triggering a protective response to limit the engine’s performance.torque derate). 2) After 4 hours of engine operation or 200 miles with P3830 active, P151B becomes active (40% torque derate). 3) After 4 hours of engine operation or 200 miles with P3830 active, P151A becomes active (5 MPH vehicle speed limit) after a: - key cycle, or - vehicle re-fuel (fuel tank volume increase > 16%), orIn this video we use the TEXA Off-Highway Kit to clear a derate on a Cummins QSF.
