SRC-110

< COMPONENT DIAGNOSIS >

B1150 CURTAIN MODULE LH

B1150 CURTAIN MODULE LH

Description

INFOID:0000000003814068

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.
