Patent ID: 8183992

Claim:
A method of indicating the status of a tire sensor monitoring system for a motor vehicle, wherein each of a plurality of tire sensors periodically emits an identifying and parameter signal and a monitor receives and processes the identifying and parameter signals when the tire sensors and the monitor are operating properly, said method comprising: (a) periodically determining whether the identifying and parameter signals emitted by the tire sensors are being received by the monitor within a pre-selected time limit; (b) periodically determining whether the parameter signals emitted by the tire sensors and processed by the monitor are within a pre-selected range of values; (c) energizing a single status indicator if: (i) all of the identifying and parameter signals of step (a) are received within the pre-selected time limit; and (ii) all of the parameter signals of step (b) are within the pre-selected range of values; and (iii) the tire sensors and monitor are operating properly; and (d) de-energizing said single status indicator if: (i) any of the said identifying and parameter signals is not received within the pre-selected time limit; or (ii) any of said parameter signals is outside the pre-selected range of values; or (iii) any of the tire sensors or monitoring system is not operating properly.
