ABSTRACT:
A system for controlling the activation of an air bag for a vehicle includes a capacitor connected to a battery via a main electric wire. The supply of electric current from the capacitor to a squib of the air bag is controlled by a first switch. Upon collision of the vehicle, the first switch is closed to allow current to flow to the squib of the air bag. The control system further includes a malfunction alarm device which is connected to the battery via an auxiliary electric wire. The supply of current from the battery to the malfunction alarm device via the auxiliary electric wire is controlled by a second switch. When an electric current path, extending between the battery and the capacitor and including the main electric wire, is interrupted, the second switch is intermittently closed to operate the malfunction alarm device. A current control device is connected between the capacitor and one end of the auxiliary electric wire connected to the malfunction alarm device, and allows electric current to flow only from the auxiliary electric wire toward the capacitor. When said second switch is opened, the battery changes the capacitor via the auxiliary electric wire.
