Abstract
A method of controlling an aspirator valve of a vacuum assisted braking system that rapidly fully opens and closes the aspirator valve when an engine of a motor vehicle has been shut-down and the current conditions indicate that ice is likely to have formed in the aspirator valve. The rapid opening and closing of the aspirator valve breaks up any ice buildup thereby de-icing the aspirator valve and allowing normal aspirator valve operation.
