1. A method for initiating and verifying operation of at least one tire pressure sensor having a plurality of modes, the method comprising:
- (i) transmitting a signal to change a sensor from a power-conserving first mode to an information-providing second mode;
(ii) causing the sensor to transmit information;
(iii) processing the information from the sensor;
(iv) determining whether the sensor is operating acceptably, whereby if the determination is that the sensor is not acceptably operating, repeating step (iii) and if the determination is that the sensor is acceptably operating, repeating steps (i), (ii), and (iii) and then proceeding to step (v);
(v) determining again whether the sensor is operating acceptably, whereby if the determination is that the sensor is not acceptably operating, repeating steps (i), (ii), (iii) and (iv) one time, and if the determination is that the sensor is acceptably operating, proceeding to step (vi);
(vi) transmitting a signal to change the sensor from the second mode to a third mode.

11. A method for initiating and verifying operation of at least one tire pressure sensor having a plurality of modes, the method comprising:
-
(i) transmitting a signal to change a sensor from a first mode to a second mode; (ii) causing the sensor to transmit information; (iii) processing the information from the sensor; (iv) determining whether the sensor is operating acceptably, whereby if the determination is that the sensor is not acceptably operating, reprocessing the information from the sensor, and if the determination is that the sensor is acceptably operating, proceeding to step (v); (v) transmitting a signal for the sensor to be in the second mode; (vi) causing the sensor to transmit information; (vii) processing the information from the sensor; (viii) determining whether the sensor is operating acceptably, whereby if the determination is that the sensor is not acceptably operating, repeating steps (i), (ii), (iii), (iv), (v), and (vii) one time, and if the determination is that the sensor is acceptably operating, proceeding to step (ix); (ix) transmitting a signal to change the sensor from the second mode to a third mode. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A system for initiating and verifying a tire pressure monitoring system, comprising:
-
a tire pressure sensor having a plurality of modes, including a first mode and a second mode; a trigger switch for transmitting a signal to the sensor for changing the sensor from the first mode to the second mode, the sensor configured to transmit information upon receipt of the signal; a receiver for receiving the information transmitted from the sensor and processing the information, the receiver configured to determine whether the sensor is operating acceptably based on the information received from the sensor, the receiver further configured to reprocess the information if determined that the sensor is not acceptably operating and to command the trigger switch to retransmit the signal if determined that the sensor is acceptably operating. - View Dependent Claims (20, 21, 22, 23, 24, 25)
