B1070 ASSIST A/B MODULE
Description
INFOID:0000000000959645
DTC B1070 [OPEN] ASSIST A/B MODULE
For passenger “AIR BAG”, crash is judged by main “G” sensor output signal and sub “G” sensor 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 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
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.
