AIR BAG SYSTEM
T–33
T
•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.
Crash Zone Sensor Handling
•Disconnecting the crash zone sensor connector or removing the crash zone sensor with the ignition
switch at ON position can cause the crash zone sensor to operate and the air bag modules and pre-
tensioner seat belts to deploy, which may seriously injure you. Before disconnecting the crash zone
sensor connector or removing the crash zone 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 crash zone sensor is subjected to shock or the sensor is disassembled, the air bag modules and
pre-tensioner seat belts may operate (deploy) suddenly and cause injury, or it may fail to operate
normally and cause a serious accident. Do not subject the crash zone sensor to shock or disassemble
the sensor.
•Because a sensor is built into the crash zone sensor, when the air bag modules and pre-tensioner seat
belts operates (deploys), there may be a problem, such as an internal malfunction, even if there is not
any external damage or deformation. If the crash zone sensor is reused, the air bag modules and pre-
tensioner seat belts may fail to operate normally and cause a serious injury. Always replace the crash
zone sensor with a new part. The crash zone sensor cannot be bench-checked or self-checked.

AIR BAG SYSTEM
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 fail 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.
Component Handling
•Oil, grease, water, etc on components may cause the air bag modules and pre-tensioner seat belts to
fall to deploy in an accident, which may cause serious injury. Do not allow oil, grease, water, etc., on
components.
•Inserting a screwdriver, etc., into the
connector of an air bag module or a pre-
tensioner seat belt may damage the connector
and cause the air bag module or the pre-
tensioner seat belt to deploy improperly,
which may cause serious injury. Do not insert
any foreign objects into the connector.
Component Reuse
•Even if an air bag module or a pre-tensioner seat belt does not deploy in a collision and does not have
any external signs of damage, it may have been damaged internally, which may cause improper
operation. Improper operation may cause serious injury. Always self-check the undamaged air bag
module or pre-tensioner seat belt to determine whether it can be reused.
