Seat Weight Sensor Handling
• The passenger-side seat and the seat weight sensor may become deformed or otherwise damaged due
to operation (deployment) of the front or side air bag in an accident. This may cause the passenger
sensing function to operate improperly and result in a serious accident. Always replace the passenger
seat and seat weight sensor with new ones after the front or side air bags have operated (deployed).
After servicing, verify that the seat operates normally and that the wiring harness is not caught. If the
collision is not hard enough to cause the front or side air bags to operate (deploy), inspect the seat
weight sensor and replace it if there is any malfunction.
SAS Control Module Handling
• Removing the SAS control module or disconnecting the SAS control module connector with the
ignition switch at the ON position can activate the sensor in the SAS control module and operate
(deploy) the air bags and pre-tensioner seat belts, which may cause serious injury. Before removing 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 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, once the air bag has operated (deployed) due to
a collision or other causes, the side air bag sensor must be replaced with a new one even if the used
one does not have any visible external damage or deformation. If the side air bag sensor is reused, the
side air bag may not operate (deploy) normally, which could result in a serious accident. Always
replace the side air bag sensor with a new one. The side air bag sensor cannot be bench-checked or
self-checked.
