1. Method of verifying valve integrity of a valve interposed between a tire and conduit assemblies for conducting fluid to or from the tire in a tire maintenance system comprising:
- closing the valve for prohibiting fluid flow into the conduit assemblies in fluid communication with the valve;
monitoring the pressure of fluid in the conduit assemblies in fluid communication with the valve for ascertaining a pressure increase therein;
updating a counter when the pressure is equal to or greater than a pressure value; and
initiating an alarm if the value of the counter is equal to or greater than a count.

Abstract
A method of verifying the integrity of a valve in service in a tire pressure management system is disclosed. The method of verifying valve integrity of a valve interposed between a tire and conduit assemblies for conducting fluid to and/or from the tire in a tire maintenance system includes closing the valve for prohibiting fluid flow into the conduit assemblies in fluid communication with the valve and monitoring the pressure of fluid in the conduit assemblies in fluid communication with the valve for ascertaining a pressure increase therein.

5. Method of verifying valve integrity of a valve interposed between a tire and conduit assemblies for conducting fluid to or from the tire in a tire maintenance system comprising:
-
closing the valve for prohibiting fluid flow into the conduit assemblies in fluid communication with the valve;
monitoring the pressure of fluid in the conduit assemblies in fluid communication with the valve for ascertaining a pressure increase therein; and
,initiating an alarm when the pressure is equal to or greater than a pressure value;
wherein the pressure value is offset by an amount of pressure anticipated in the conduit assemblies from a make-up or bleed fluid supply.

6. Method of verifying valve integrity of a valve interposed between a tire and conduit assemblies for conducting fluid to or from the tire in a tire maintenance system comprising:
-
closing the valve for prohibiting fluid flow into the conduit assemblies in fluid communication with the valve;
monitoring the pressure of fluid in the conduit assemblies in fluid communication with the valve for ascertaining a pressure increase therein; and
,initiating an alarm when the pressure is equal to or greater than a pressure value;
wherein said initiating occurs within a predetermined time and the predetermined time is offset by an amount of time related to a rate of fluid supply anticipated in the conduit assemblies from a make-up or bleed fluid supply.

7. A method for verifying valve integrity of a wheel end valve, comprising the steps of:
-
venting a conduit disposed between a fluid source and said wheel end valve, said wheel end valve disposed between a tire and said conduit;
determining the pressure within said conduit after said venting step; and
comparing said pressure to a pressure limit corresponding to an anticipated pressure increase resulting from air provided to said conduit from said fluid source to counteract fluid leakage in said conduit. - View Dependent Claims (8, 9, 10)
