Zusammenfassung:	PROBLEM TO BE SOLVED: To surely determine the fault of a sensor module in an early stage when the sensor module is disabled. SOLUTION: Data are transmitted and received successively between the sensor modules attached inside respective tires and a plurality of antennas respectively. Among error counters provided for the respective sensor modules, the error counter of the sensor module which could transmit and receive the data is cleared (S13), and the error counter of the sensor module which could not transmit or receive the data is counted up (S16). When the count value of the error counter becomes larger than a sensor fault determination value, the sensor module relating to the error counter is determined as a fault. COPYRIGHT: (C)2007,JPO&INPIT
