Abstract
In a tire sensor monitoring system for a motor vehicle, each of a plurality of tire sensors periodically emits an identifying signal and a parameter signal and the monitoring system receives and processes the identifying and parameter signals. A method of indicating the status of the monitoring system comprises periodically determining whether the identifying and parameter signals emitted by the tire sensors are being received within preselected time limits, energizing a status indicator if all of said identifying and parameter signals are received within the preselected time limits, de-energizing the status indicator if any of said identifying and parameter signals is not received within the preselected time limits, periodically determining whether the parameter signals emitted by the tire sensors are within a preselected range of values, energizing the status indicator if all of said parameter signals are within the preselected range of values; and de-energizing the status indicator if any of said parameter signals is outside the preselected range of values.
