a controller coupled to the aftertreatment system heater, the controller configured to:
determine a condition of an exhaust gas from the engine;
compare the condition of the exhaust gas to a predefined threshold;
in response to determining that the condition of the exhaust gas does not meet the predefined threshold, determine whether an engine operating condition is met for activating a cylinder deactivation operating mode for the engine;
