Second Generation XM (2011-2026) / Kia Sorento XM 2011-2026 Service Manual / Restraint / Airbag Module / Passenger Airbag (PAB) Module Description
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.
