Passenger Air Bag (Inflator) Module

WARNING: Never attempt to disassemble or repair 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".




Passenger air bag (inflator) module consists of inflatable bag, inflator and trim cover, and is mounted above glove box in instrument panel on the passenger side.




Passenger inflator consists of initiator, burst disk and inflator gas tank.
When vehicle is in frontal crash of sufficient force, SDM causes current to flow through passenger deployment loop. Current passing through initiator causes a chemical reaction to occur. This chemical reaction generates pressure, depressing burst disk which releases stored gas rapidly inflating air bag.




Once deployment starts, expansion force of the inflatable bag forces trim cover and move up.
