Description
INFOID:0000000005241166
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 a 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.
DTC Logic
INFOID:0000000005241167
