ABSTRACT:
An electronic control unit in an airbag device generates a data signal for identifying a type of control unit and outputs the data signal. The output data signal is received by a light emitting diode causing the light emitting diode to turn on and off responsive to the data signal. It is possible to easily identify whether the electronic control unit is correctly installed in a vehicle even after the airbag device is mounted in the vehicle, by detecting the variation of the light emitting state of the diode by a photo sensor or the like.
