WARNING: This page is about a different car, the 2024 Jeep Grand Cherokee L. However, it is still accessible from the selected car via links, so may be relevant.

The MIL light will illuminate or flash depending on severity of the misfire.
During a severe misfire (MIL Light flashing) the PCM will disable the Fuel Injector of the affected cylinder(s) for a calibrated number of engine revolutions to prevent damage to the Catalytic Converter. When the engine rev counter has reached the calculated threshold the Fuel Injector is turned back on. If a misfire is still occurring, the injector is disabled again. This cycle will continue until the misfire has stopped.
If the vehicle is equipped with the stop/start feature, the system will be disabled when this DTC is active.
