To determine whether a faulty sensor having been diagnosed as being faulty before is connected to a control apparatus. An air bag ECU 100 includes an ECU communication unit 181 communicating with ah external sensor (for example, a front right acceleration sensor 600) and a faulty sensor mount determination unit 182 determining whether a faulty sensor having been diagnosed as being faulty before is connected to the air bag ECU 100 based on failure history data indicating whether the external sensor has been diagnosed as being faulty before. The faulty sensor mount determination unit 182 compares identification data recorded in, for example, a faulty sensor ID recording unit 184, for individually identifying an external sensor having been diagnosed as being faulty before with the identification data of the external sensor connected to the air bag ECU 100 and determines whether a faulty sensor is connected to the air bag ECU 100. |
