Hyundai Sonata: Airbag Module / Passenger Airbag (PAB) Module Description and Operation
Passenger Airbag (PAB) module is located in the passenger
crash pad. This PAB contains 2 firing squibs of airbag and 1 firing
squib of active vent. Depending of crash speed or the tightening of seat
belt, it is decided a timing about both 2 firing squibs of airbag and 1
firing squib of active vent. At the moment of vehicles collisions, the
firing squib of active vent make airbag distended and then consecutively
leaked gases of airbag through a hole at once. These operations reduce
an injury of the passenger's head. At first, the active vent sets a
rapid deployment of airbag by keeping the pressure, after deployment of
airbag it emits the gases of upper airbag. The Working Principle of
Tether Cutter: When receive an electrical signal, Tether Cutter cuts a
strap which is been attached Active vent in order to open a hole of
upper airbag.The working range of Active Vent
1) If occupant in passenger seat is not belted, active vent is disposed in the end of crash event regardless of crash severity.
2) If occupant is belted and crash severe enough to require 2
stage passenger airbag deployment is occurred, active vent is activated
to optimize occupant protection.
3) Low-Speed + Belted : Inflator of Primary Fire + 2 Stage & Active Vent disposal in the end of crash event.
Never attempt to measure the circuit resistance of the airbag
module (squib) even if you are using a specified tester. If the circuit
resistance is measured with a tester, accidental airbag deployment will
result in serious personal injury. |
