Okay. Both of those faults are simply inducement faults which are indicating that a derate is active due to an issue with the SCR or DPF systems. This will take some diagnostics with a scanner or PC. The only real thing you can do is disconnect the speed sensor on the rear of the trans and this will stop the derate and allow you to go on your way.Anybody knows how to make ECU doesn't limit torque due to Adblue/SCR fails (25% to 40% limitation according max permissible weight)? Any ideas? For example is it possible to code truck's ECU like military truck? BW

Different egr, dpf, scr, ECM. Keep maintenance records and keep that fuel clean.Oct 24, 2023 · Excessive coolant temperature is one of the most frequent reasons an ECM will enforce a derate. The coolant temperature sensor provides constant real-time readings to the ECM. If the coolant exceeds the maximum predefined limit, usually around 230°F, the ECM will immediately derate engine power. This protects the engine from overheating damage ... Anybody knows how to make ECU doesn't limit torque due to Adblue/SCR fails (25% to 40% limitation according max permissible weight)? Any ideas? For example is it possible to code truck's ECU like military truck? BWPosted by u/Disastrous_Skill8428 - No votes and no commentsThe Cummins engine is designed with a "torque derate curve". This basically means that as certain conditions are met, the ECM will automatically adjust the torque output of the motor to compensate. These conditions can be changes in atmospheric temperature and pressure, fuel quality, and altitude. By reducing torque output, the engine is ...

The dosing valve is responsible for injecting DEF into the exhaust stream and, if it malfunctions, your engine will be forced into derate. This is because the ECU will not receive the correct information about the amount of DEF in the system. As a result, will not be able to properly regulate the engine’s emissions.An 'inducement' may also be referred to as an engine derate There are three primary events that could initiate an inducement/derate: (1) Low Diesel Exhaust Fluid (DEF) level, (2) Incorrect fluid in DEF tank, and (3) SCR Faults. The driver will recognize this as a performance penalty initiated by the Electronic Control Module (ECM ...To start, "Poor DEF Quality" is highly suggestive and worded in a way that can be misleading. I believe the best way to word this message would be "High NOx Emissions Detected" or "Poor SCR Efficiency" (some mfg use this terminology). Either of these would be a more accurate representation of what is wrong and better encompasses its potential ...
