AIR BAG SYSTEM
Air Bag Module Handling
• A live (undeployed) air bag module may
accidentally deploy when it is handled and
cause serious injury. When carrying a live
(undeployed) air bag module, point the front
surface away from your body to lessen the
chance of injury in case it deploys.
A live (undeployed) air bag module placed face
down on a surface is dangerous. If the air bag
module deploys, the motion of the module can
cause serious injury. Always face the front
surface up to reduce the motion of the module
in case it accidentally deploys.
Side Air Bag Module Handling
• When the side air bag module deploys due to a
collision, the interior of the seat back (pad,
frame, etc.) may become damaged. If the seat
back is reused and the side air bag module
does not deploy properly, a serious accident
may result. When the side air bag module
deploys, always replace both the side air bag
module and the seat back (pad, frame, trim)
with new parts. After service, confirm that the
seat operates normally and that the harness is
positioned properly.
SAS Unit Handling
• Disconnecting the SAS unit connector or
removing the SAS unit with the ignition switch
at ON position can cause the air bag modules
to deploy, which may seriously injure you.
Before disconnecting the SAS unit connector
or removing the SAS unit, turn the ignition
switch to LOCK position, then disconnect the
negative battery cable and wait for more than 1
minute to allow the backup power supply of
the SAS unit to deplete its stored power.
• Connecting the SAS unit connector without
firmly installing the SAS unit to the vehicle is
dangerous. The crash sensor inside the
control module may send an electrical signal
to the air bag modules. This will deploy the air
bag modules, which may result in serious
injury. Therefore, before connecting the
connector, firmly mount the control module to
the vehicle.
• For vehicles with a single point sensor, once
an air bag module is deployed due to an
accident or other causes, the SAS unit must be
replaced with a new one even if the used one
does not have any external signs of damage.
The used SAS unit may have been damaged
internally which may cause improper
operation, resulting in major injuries or even
death. The used single point SAS unit cannot
be bench-checked or self-checked.
Side Air Bag Sensor Handling
• Disconnecting the side air bag sensor
connector or removing the side air bag sensor
with the ignition switch at ON position can
cause the side air bag sensor to operate and
the side air bag module to deploy, which may
seriously injure you. Before disconnecting the
side air bag sensor connector or removing the
side air bag sensor, always turn the ignition
switch to LOCK position, then disconnect the
negative battery cable and wait for more than 1
minute to allow the backup power supply of
the SAS control module to deplete its stored
power.
• If the side air bag sensor is subjected to shock
or the sensor is disassembled, the side air bag
module may operate (deploy) suddenly and
cause injury, or it may fail to operate normally
and cause a serious accident. Do not subject
the side air bag sensor to shock or
disassemble the sensor.
• Because a sensor Is built Into the side air bag
sensor, when the side air bag module operates
(deploys), there may be a problem, such as an
internal malfunction, even if there is not any
external damage or deformation. If the side air
bag sensor Is reused, the side air bag module
may fall to operate normally and cause a
serious injury. Always replace the side air bag
sensor with a new part. The side air bag
sensor cannot be bench-checked or
self-checked.
Pre-tensioner Seat Belt Inspection
• Inspecting a pre-tensioner seat belt using an
ohmmeter can deploy the pre-tensioner seat
belt, which can cause serious injury. Do not
use an ohmmeter to inspect the pre-tensioner
seat belt. Always use the on-board diagnostic
to diagnose the pre-tensioner seat belt for
malfunctions.
