B1147 CURTAIN MODULE RH

Description

INFOID:0000000000959735

DTC B1147 [GND-SHORT] CURTAIN MODULE RH

For curtain air bag, crash is judged by main “G” sensor output signal (left side: left satellite sensor, right side:
right  satellite sensor) and sub “G” sensor (right and left GP in center unit).

OPERATION

In case of 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 gener-
ate hot gases that flow into the air bag through a filter and expand the bag.

STRUCTURE

Curtain air bag module mainly consists of air bag and inflator which inflates air bag.

INSTALLATION

Curtain air bag module is installed on the roof side with fixed bolts.
