A method of operating the machine includes steps of determining whether preconditions are satisfied for changing the master electronic control module from an operating state to a low power state, and determining whether preconditions are satisfied for changing the secondary electronic control module from an operating state to a power off state by opening a power supply circuit. The method also includes steps of changing the secondary electronic control module from the operating state to the power off state, and changing the master electronic control module from the operating state to the low power state.
