Now look at the case, where is the generator responsible for the manifestation of the work of a pillow of safety - must all be safe and without any damage. Make an attempt combining pillows of safety to the steering column of the vehicle. The deployment design should coincide with an emergency situation. Any distortions should not be.

Wait half a minute, and "short-circuit" the contacts are numbered No. 4 and No. 13 of connector. Now look at the instrument panel. It is seen that there is a blinking light bulbs.
