B1212, B1213, B1214 RH1 SAT-SENS
DescriptionINFOID:0000000003941406
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 defines 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.
