Passenger Air Bag (Inflator) Module
PASSENGER AIR BAG (INFLATOR) MODULEWARNING:
- Never attempt to disassemble or repair the passenger air bag (inflator) module. If any abnormality is found, be sure to replace it with new one as an assembly.
- When handling it, be sure to read "Service Precaution" under "ON-VEHICLE SERVICE" and observe each instruction.
The passenger air bag (inflator) module consists of an inflatable bag, an inflator and a trim cover, and is mounted above the glove box in the instrument panel on the passenger side.
The passenger inflator consists of initiator, burst disk and inflator gas tank.
When the vehicle is in a frontal crash of sufficient force, the SDM causes current to flow through the passenger deployment loop. Current passing through the initiator causes a chemical reaction to occur. This chemical reaction generates pressure, depressing a burst disk which releases the stored gas rapidly inflating the air bag.
Once deployment starts, expansion force of the inflatable bag forces the trim cover and move up.
