B1080, B1096 DRIVER AIRBAG MODULE

Description

INFOID:0000000005513559

For driver air bag module, crash is judged by main “G” sensor output signal and safing algorithm in front direc-
tion.

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

Driver air bag module mainly consists of air bag and inflator that inflates air bag.

INSTALLATION

Driver air bag module is installed on the center of steering wheel with fixed bolts.

B1081 PRE-TEN FRONT RH

Description

INFOID:0000000005513562

DTC B1081 [OPEN] PRE-TEN FRONT RH

For front RH seat belt pre-tensioner, crash is judged by main “G” sensor output signal and Safing algorithm in
front direction.

OPERATION

In the case of a frontal collision that exceeds specified impact level, the air bag diagnosis sensor unit detects
the deceleration caused by collision. It restrains the passenger with seat belt easing the stress on passengers
chest with load limiter.

STRUCTURE

The restraint system for front seat occupant consists of the pre-tensioner mechanism and load limiter mecha-
nism.

INSTALLATION

Front RH seat belt pre-tensioner is installed on the underside of center pillar with fixed nuts.
