An airbag ECU includes a voltage detection section that detects a voltage in a power supply supplied to other control units (for example, front passenger seat occupancy sensing ECU). In addition, the airbag ECU includes a timer that measures an elapsed time after the voltage detected by the voltage detection section falls in a preset voltage range and a recording section that records the elapsed time measured by the timer on a memory when a failure of the other control units is detected.
