< COMPONENT DIAGNOSIS >
B1152 CURTAIN MODULE LH
B1152 CURTAIN MODULE LH
Description
INFOID:0000000003814074
For LH side curtain air bag module, crash is judged by main “G” sensor output signal (left side: LH satellite
sensor, right side: RH satellite sensor) and safing algorithm (left and right GP 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
LH side curtain air bag module mainly consists of air bag and inflator which inflates air bag.
INSTALLATION
LH side curtain air bag module is installed on the roof side with fixed bolts.
