B1130 SIDE MODULE RH

B1130 SIDE MODULE RH

Description

INFOID:0000000003595955

DTC B1130 [VB-SHORT] SIDE MODULE RH

For front RH 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 RH side air bag module mainly consists of air bag and inflator which inflates air bag.

INSTALLATION

Front RH side air bag module is installed on the side of front seatback with fixed nuts.
