Kia Cadenza: 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 the specified tester. If the
circuit resistance is measured with a tester, accidental airbag
deployment will result in serious personal injury. |
