Description

INFOID:0000000005513547

DTC B1066, B1071 [VB-SHORT] ASSIST A/B MODULE

For front passenger air bag module, crash is judged by main “G” sensor output signal and Safing algorithm in
front direction.

OPERATION

In the case of a frontal 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 passenger air bag module mainly consists of air bag and inflator which inflates air bag.

INSTALLATION

Front passenger air bag module is installed on the instrument panel with fixed bolts.
