B1212, B1213, B1214 RH1 SAT-SENS

Description

INFOID:0000000005513883

Main “G” sensor generates signal voltage, when it detects deceleration beyond the specified level by vehicle
side collision.

OPERATION

When air bag diagnosis sensor unit judges both signal voltage of the “G” sensor and the Safing algorithm to be
that of collision which exceeds specified level, the driving circuit switches on and feeds the electric ignitor of
both the front side air bag and side curtain air bag.

STRUCTURE

Integrated type of the “G” sensor element for side collision with output terminals for signal voltage.

INSTALLATION

RH satellite sensor is installed at the underside of center pillar with fixed nuts.
