A method of monitoring operation of an adjustable shutter adapted for cooling a powertrain in a vehicle includes commanding the shutter to adopt a position and assessing whether the shutter has adopted the commanded position. The method also includes generating a first signal if the shutter has adopted the commanded position, and commanding the shutter to perform a first retry to adopt the commanded position if the shutter has not adopted the commanded position. The method additionally includes generating a second signal if the shutter has adopted the commanded position on the first retry. A vehicle using a controller to perform such a method is also provided.
