Abstract

A method and system of controlling a vacuum-driven actuator in a vehicle. The method includes determining an amount of vacuum available to actuate the actuator, determining whether the available vacuum is sufficient to actuate the actuator, actuating the actuator only when the available vacuum is sufficient, and preventing actuation of the actuator when the available vacuum is insufficient.
