B1134 SIDE MODULE LH

Description

INFOID:0000000003367683

DTC B1134 [OPEN] 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 Safing algorithm (in air bag diagnosis sensor unit).

OPERATION

In the case of a 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
generate 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.

DTC B1145 [OPEN] CURTAIN MODULE RH

For RH 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 (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

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

B1146 CURTAIN MODULE RH

Description

INFOID:0000000003367701

DTC B1146 [VB-SHORT] CURTAIN MODULE RH

For RH 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 (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

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

INSTALLATION

RH side curtain air bag module is installed on the roof side with fixed bolts.
