Abstract
An air bag operation device which employs only one CPU module to guarantee sufficient fail-safety in the operation of the air bag without increasing the scale of the hardware. A plurality of crash-discriminating programs of different versions and a plurality of self-diagnosing programs of different versions are executed by a single CPU module, a signal is fed to an air bag igniting device based upon a comparison of the discriminated results by the plurality of crash-discriminating programs, and a signal is fed to an abnormality alarm device based upon comparison of the discriminated results of the plurality of self-diagnosing programs.
