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.
