<p>A diagnostic method for sensing and reacting to conditions indicative of leakage of an inflatable tire (12/14), the pressurization of which tire is measured and controlled by an on-board CTIS (10), said CTIS automatically measuring inflation pressurization of said tire at predetermined extended time intervals and, in the absence a sensed system fault condition or pressure modification commands, assuming a steady-state condition during each of said extended intervals between automatic pressure measurements, said method characterized by: At the completion of each automatic pressure measurement operation and pressure adjustment operation, after desired tire pressurization is sensed, assuming steady-state conditions for a relatively short period of time, then performing a confirming pressure measurement to sense change in tire pressurement during said short period of time, and; if the sensed change in tire pressurization is less than a referenced value, allowing said CTIS to assume steady-state conditions until expiration of said extended time interval; and if the sensed change in tire pressurization is equal to or greater than said referenced value, causing said CTIS to pressurize the tire to desired pressurization and to perform continuing automatic tire pressurization measurements after shortened time intervals of steady-state condition.</p> |
