has been enabled if the limited range of operation has not been enabled the controller determines if the cumulative value of aeration exceeds a first predetermined threshold block 58 when the cumulative value of aeration does not exceed the first predetermined threshold the 100 millisecond execution of the algorithm block 66 ends without further action when the cumulative value of aeration exceeds the first predetermined threshold the controller 10 enables the limited range of operation of the output device in subsequent operations block 62 and the method ends block 66 if the limited range of operation of the output device has not been enabled the controller 10 determines if the cumulative value of aeration is less than a second predetermined threshold block 60 when the cumulative value of aeration is less than the second predetermined threshold the method disables the limited range of operation of the output device in subsequent operations block 64 and the algorithm ends block 66 when the cumulative value of aeration is not less than the second predetermined threshold the method will continue to enable the limited range of operation of the output device in subsequent operations block 62 and the method will end block 66 when the engine 5 and controller 10 are using.
