Understanding and Resolving "SCR Error Torque Derate 25 International"

Derate. A derate selection electronically reduces the rated thrust of the engine to either one or more prespecified values or by a selectable percentage of the normal flat rated thrust. As this new thrust limit cannot be exceeded during the takeoff phase, critical speeds such as V mcg and V mca change from those associated with full rated thrust.Additional Information: 1) DEF injection is disabled. 2) After 1 hour of engine operation or 50 miles with P3812 active, P1518 becomes active (25%. torque derate). 3) After 4 hours of engine operation or 200 miles with P3812 active, P151B becomes active. (40% torque derate). 4) After 4 hours of engine operation or 200 miles with P3812 active ...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.But it's giving three errors which are not in SIS. I have full access to SIS. The first says it's derating due to the cold. (No error#) But this happens when it's 45* outside and 55* outside, and even comes when the machine is warmed up and I turn it off/on and the coolant is 172*! I thought maybe this is a setting in ET where derate for cold ...

The first thing to do is to stop your vehicle and do a visual inspection. Better yet, call your service workshop for scanning. Check your DEF tank first and check for any possible contaminants.In a de-rate condition, the ECM (Engine Control Module) limits the horsepower and/or speed of the truck, sometimes to as slow as 5 mph. The ECM is hard-coded to do this when it detects certain problems with the engine such as low coolant, low oil pressure, etc and especially any fault codes related to the emissions system.Wrap Up. A Peterbilt derate happens because of numerous reasons. It could be due to the emissions system, or the DPF and SCR catalyst efficiency errors. When these problems arise, an engine derate occurs. For issues linked with emissions, the vehicle is likely to get into a 5 PMH derate enabled by your ECU.SRT: Engine Protection Torque Derate - Condition Exists.

A truck’s derate is a process that reduces the amount of engine power when the truck is driving. The derating process is controlled by the engine control module (ECM). The reason why the engine derates is to avoid damaging the engine. But a derated engine is not always a good thing, as it could indicate a problem with the emissions system, or ...
