Description
INFOID:0000000001694575
DTC B1113, B1114 [UNIT FAIL] SATELLITE SENS RH
Main “G” sensor generates signal voltage, when it detects deceleration beyond the specified level by vehicle
side collision.
OPERATION
When ACU define the both signal voltage of the “G” sensor and the Safing sensor to be that of collision which
exceeds specified level, the driving circuit switches on and feeds the electric ignitor of both the side air bag
and 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.
