The present concept is method of controlling a vehicle's engine idle and includes the steps of monitoring a vehicles operating parameters with a controller and comparing parameters to preselected shutdown conditions. In the event shutdown conditions are met and the key is not in the ignition, the controller warns operator of impending shutdown. The controller intercepts the ignition key signal and simulates the vehicle key to be in the run position such that vehicle functions are operable as if key is in run position. The controller shuts down engine. The method may also include the steps of: the controller intercepting the ignition key signal and simulating the vehicle key to be in the accessory position such that vehicle functions are operable as if key is in accessory position.
