  "textContent": "A system includes an aftertreatment system coupled to an engine and a controller communicably coupled to the engine and the aftertreatment system, the controller is configured to perform operations. The operations include receiving an engine braking request, and, responsive to receiving the engine braking request, enabling an engine braking operation whereby at least one engine braking mode of a plurality of engine braking modes is enabled and implemented. The operations include receiving a temperature value regarding a temperature of the aftertreatment system, comparing the temperature value to a first threshold or a second threshold, and selecting and implementing one of the one or more engine braking modes based on comparing the temperature value to the first threshold or the second threshold.",
