WARNING: This page is about a different car, the 2018 Nissan Titan XD. However, it is still accessible from the selected car via links, so may be relevant.
The ECM monitors the engine operation for critical Selective Catalytic Reduction (SCR) current DTCs. If the DTCs are current for an extended period of time and no repair action has been taken, the ECM will limit the engine torque depending on which SCR DTCs are current.
