B1131 SIDE MODULE RH
Description
INFOID:0000000005241184
For front RH side air bag module, crash is judged by main “G” sensor output signal (left side: LH satellite sen-
sor, right side: RH satellite sensor) and safing algorithm (in air bag diagnosis sensor unit).
OPERATION
In case of frontal collision whose acceleration exceeds the specified level, the ignition materials are ignited by
electric ignition system. The system burns the gas generating materials resulting in a chemical reaction. This
generates hot gases that flow into the air bag through a filter and expand the bag.
STRUCTURE
Front RH side air bag module mainly consists of air bag and inflator that inflates air bag.
INSTALLATION
Front RH side air bag module is installed on the side of front seatback with fixed nuts.
