B1145 CURTAIN MODULE RH
Description
INFOID:0000000005513637
DTC B1145 [OPEN] CURTAIN MODULE RH
For RH side curtain air bag module, crash is judged by main “G” sensor output signal (left side:LH satellite
sensor, right side:RH satellite sensor) and Safing algorithm (left and right GP in air bag diagnosis sensor 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
RH side curtain air bag module mainly consists of air bag and inflator which inflates air bag.
INSTALLATION
RH side curtain air bag module is installed on the roof side with fixed bolts.
