Scr torque derate.

A System Fault refers to a malfunction or failure in the Selective Catalyst Reduction system of a vehicle. The SCR system is responsible for reducing emissions by injecting diesel exhaust fluid (DEF) into the exhaust stream to react with nitrogen oxides (NOx). When a System Fault occurs, it indicates a problem that requires attention.

Didn't wait for it to Derate. Did a Regen and check engine light and DEF warning light went off. A yellow engine light not labeled stayed on. Delivered then did a long deadhead to pickup a lite load in New York. During that trip, the plain yellow light next to the check engine light went off. During all this, I didn't see a DPF light come on.

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.

Okay. If the acm sees that the pump can put out 130 psi, the inducement should go away. But with the time being driven with the key cycle this will more than likely get the spn 4094 fault which is the 5 mph derate within the 100 miles as it is already in a torque derate.The engine load is based on torque; i.e., 100 % engine load implies the maximum torque at a particular engine speed. For instance, if the maximum torque (100 % load) is 300 N·m at an engine speed of 1250 rpm, the 50 % load condition corresponds to a torque of 150 N·m at the same engine speed. In this way, 16 conditions in total were carried out.SPN 1569 FMI 31 - SCR Tamperproof Warning and Protection System Inducement Severe. Fault Overview.
