No one unrelated parameter will be changed. 50 minutes (or lessOn Test Vehicle 1, the warnings and inducements were implemented as expected. CARB deemed the warnings effective in drawing the driver's attention to the need for SCR-related service. The initial inducement incorporated in Test Vehicle 1 was a 25 percent engine torque derate and a 55 mph speed limitation.

DEF Dosing Valve Failure. 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.• "Selective Catalytic Reduction (SCR) Service", page 13 • "Engine Turbocharger Failure", page 13 • "Precautions for Installation of Replacement Engine Turbochargers", page 23 Note: Information is subject to change without notice.

Derating servo motors is relatively easy. Induction motors (asynchronous or squirrel-cage motors) behave differently than permanent magnet motors. Due to the design of the motor, it operates at a rated speed less than the synchronous speed, by a difference known as the slip speed. Because the motor has this slip speed, there is not a linear ...

Then connect your cathode side onto your negative lead. Follow the designated resistance value presented in your ohmmeter. When there is a high resistance value, this means that your SCR system is working just right. On the other hand, a low resistance value presents a fault to the system. Hence, you will need to replace or repair …

Step 2: Thoroughly Inspect and Repair Mechanical Issues. Here’s where the true repair work begins. Once you’ve diagnosed the fault codes and pinpointed the failing engine components involved with the derate, it’s time to physically inspect and rectify the underlying mechanical issues.Technician: Joe Green. Typically a battery disconnect won't have any effect on a derate issue on these. If it did have any aftertreatment issues, you typically have to do a reset on whatever system you're having the issue with. In this case, since you don't have any lights or codes, I'm thinking you have something that failed in range.SCR CATALYST Do not perform an SCR catalyst reset with Test Plan ABL-DIT-B1365_D7USANAB-SCR system: Adjustment – V.20 (replacement of the SCR cat) unless the SCR cat has been replaced.
