Description
INFOID:0000000001694533
DTC B 1065, B1070 [OPEN] ASSIST A/B MODULE
For front passenger air bag module, crash is judged by main “G” sensor output signal and sub “G” sensor 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.
