B1135 SIDE MODULE LH

Description

INFOID:0000000001694605

DTC B1135 [VB-SHORT] SIDE MODULE LH

For front LH 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 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 LH side air bag module mainly consists of air bag and inflator which inflates air bag.

INSTALLATION

Front LH side air bag module is installed on the side of front seatback with fixed nuts.
