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 feed 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

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