B1150 CURTAIN MODULE LH

Description

INFOID:0000000005513649

DTC B1150 [OPEN] CURTAIN MODULE LH

For LH side curtain 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 (left and right GP in air bag diagnosis sensor unit).

OPERATION

In case of collision whose acceleration exceeds the specified level, the ignition materials are ignited by electric
ignition system. The system burns and introduces the chemical reaction of gas generating materials to gener-
ate 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.
