the SAS control module or disconnecting the SAS control module connector, always turn the
ignition switch to the LOCK position, disconnect the negative battery cable, and then wait for 1 min
or more to allow the backup power supply of the SAS control module to deplete its stored power.



Connecting the SAS control module connector with the SAS control module not securely fixed to
the vehicle is dangerous. The sensor in the SAS control module could send an electrical signal to the
air bag modules and pre-tensioner seat belts. This will operate (deploy) the air bags and pre-
tensioner seat belts, which may result in serious injury. Therefore, before connecting the connector,
securely fix the SAS control module to the vehicle.



Because a sensor is built into the SAS control module, once the air bags and pre-tensioner seat belts
have operated (deployed) due to a collision or other causes, the SAS control module must be
replaced with a new one even if the used one does not have any visible external damage or
deformation. The used SAS control module may have been damaged internally, which may cause
improper operation. If the SAS control module is reused, the air bags and pre-tensioner seat belts
may not operate (deploy) normally, which could result in a serious accident. Always replace the
SAS control module with a new one. The SAS control module cannot be bench-checked or self-
checked.

CRASH ZONE SENSOR HANDLING



Removing the crash zone sensor or disconnecting the crash zone sensor connector with the ignition
switch at the ON position can activate the crash zone sensor and operate (deploy) the air bags and
pre-tensioner seat belts, which may cause serious injury. Before removing the crash zone sensor or
disconnecting the crash zone sensor connector, always turn the ignition switch to the LOCK
position, disconnect the negative battery cable, and then wait for 1 min or more 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 bags and pre-
tensioner seat belts may accidentally operate (deploy) and cause injury, or the system 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, once the air bags and pre-tensioner seat belts
have operated (deployed) due to a collision or other causes, the crash zone sensor must be replaced
with a new one even if the used one does not have any visible external damage or deformation. If
the crash zone sensor is reused, the air bags and pre-tensioner seat belts may not operate (deploy)
normally, which could result in a serious accident. Always replace the crash zone sensor with a new
one. The crash zone sensor cannot be bench-checked or self-checked.

SIDE AIR BAG SENSOR HANDLING



Removing the side air bag sensor or disconnecting the side air bag sensor connector with the
ignition switch at the ON position can activate the side air bag sensor and operate (deploy) the side
air bag, which may cause serious injury. Before removing the side air bag sensor or disconnecting
the side air bag sensor connector, always turn the ignition switch to the LOCK position, disconnect
the negative battery cable, and then wait for 1 min or more 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 may
accidentally operate (deploy) and cause injury, or the system may fail to operate normally and

PRE-TENSIONER SEAT BELT INSPECTION



Inspecting a pre-tensioner seat belt using a tester can operate (deploy) the pre-tensioner seat belt,
which may cause serious injury. Do not use a tester to inspect a pre-tensioner seat belt. Always use
the on-board diagnostic function to diagnose the pre-tensioner seat belt for malfunctions.

AIR BAG SYSTEM COMPONENT DISASSEMBLY



Disassembling the air bag system components could cause it to not operate (deploy) normally.
Never disassemble any air bag system components.

AIR BAG MODULE, PRE-TENSIONER SEAT BELT HANDLING



Oil, grease, or water on the air bag modules may cause the air bags and pre-tensioner seat belts to
fail to operate (deploy) in an accident. Never allow oil, grease, or water to get on the air bag
modules or pre-tensioner seat belts.



Inserting a screwdriver or similar object 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
operate (deploy) improperly, which may cause serious injury. Never insert any foreign objects into
the air bag module or seat belt connectors.

SEAT WEIGHT SENSOR HANDLING



The seat weight sensor has a built-in strain gauge which may operate improperly if the sensor is
dropped by itself or when installed to the seat. If it is dropped, replace the seat weight sensor with a
new one.



Oil, grease, or water on the seat weight sensor may cause the system to operate (deploy)
improperly. Never allow oil, grease, or water to get on the seat weight sensor.



Foreign material in the seat weight sensor components may cause the system to operate (deploy)
improperly. Always make sure that no foreign material can get into the seat weight sensor.



Disassembling the seat weight sensor, or tightening any of the nuts and bolts installed to the sensor
body may cause it to operate (deploy) improperly. Never disassemble the seat weight sensor or
tighten any of the nuts or bolts installed to the body of the sensor.

AIR BAG MODULE, PRE-TENSIONER SEAT BELT REUSE



Even if an air bag module or a pre-tensioner seat belt does not operate (deploy) in a collision and
does not have any external signs of damage, it may have been damaged internally, which may cause
improper operation. Before reusing a live (undeployed) air bag module and the pre-tensioner seat
belts, always use the on-board diagnostic to diagnose the air bag module and the pre-tensioner seat
belts to verify that they have no malfunction.
