Air Bag Module
WARNING: This page is about a different car, the 1996 Volvo 850. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Volvo recommends air bag modules and seat belt tensioners be replaced every 10 years to maintain reliability.
Each air bag module consists of an inflatable air bag and inflator unit. Gas generator and ignitor make up the inflator unit, which is mounted to rear of air bag module. A 2-pin electrical connector with gold-plated terminals is mounted to inflator unit. If 2-pin connector is disconnected for any reason, a safety shorting spring inside 2-pin connector spreads open, touching both terminals. This prevents accidental air bag deployment by static electricity or careless handling.
