Description

INFOID:0000000000959723

DTC B1137 [SHORT] SIDE MODULE LH

For side air bag, crash is judged by main “G” sensor output signal (left side: left satellite sensor, right side: right
satellite sensor) and sub “G” sensor (right and left GP in center 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

Front side air bag module mainly consists of air bag and inflator which inflates air bag.

INSTALLATION

Front side air bag module is installed on the side of front seat back with fixed nuts.
