Be sure to read “Precautions on Service and
Diagnosis of Air Bag System” before starting
to work and observe every precaution during
work. Neglecting them may result in personal
injury or inactivation of the air bag system
when necessary.

Removal
1) Disconnect negative (–) cable at battery.
2) Disable air bag system referring to “Disabling Air
Bag System”.
3) Remove console box referring to “Console Box
Components in Section 9H”.
4) Remove G sensor referring to “G Sensor Removal
and Installation (4WD Model) in Section 4E” and its

Removal
1) Disconnect negative (–) cable at battery.
2) Disable air bag system referring to “Disabling Air
Bag System”.
3) Remove front bumper referring to “Front Bumper
and Rear Bumper Components in Section 9K”.
4) Disconnect forward impact-sensor connector (1)
sliding connector outer (2) as shown.
5) Remove forward impact-sensor bolt (3) and forward
impact-sensor (4) from apron-side-member (driver
side) (5).
Installation
CAUTION!
Proper operation of forward impact-sensor
requires sensor be rigidly attached to vehicle
structure and that the arrow on sensor be
pointing toward the front of the vehicle.

1) Check that none of the following faulty conditions
exists.
• Bend, deformity or rust of front panel.
• Foreign matter on mating surface of sensor.
2) Install forward impact-sensor (1) to apron-side-
member (driver side) (3) and tighten mounting bolt
(2) to specified torque.
Tightening torque
Forward impact-sensor mounting bolt (a): 9 N·m
(0.9 kgf-m, 6.5 lb-ft)3) Connect forward impact-sensor connector (4) by
pushing connector till click is heard from it.
4) Install front bumper referring to “Front Bumper and
Rear Bumper Components in Section 9K”.
5) Enable air bag system referring to “Enabling Air Bag
System”.
6) Connect negative (–) cable at battery.
Forward Impact-Sensor InspectionS6RW0D8206014
WARNING!
During service procedures, be very careful
when handling a sensor.
• Never strike or jar a sensor.
• A sensor and mounting bracket bolts must
be carefully torqued to assure proper
operation. Under loose connection, it
could cause improper operation of the air
bag system.

CAUTION!
• Never disassemble forward impact-sensor.
• Sensor should be replaced when it was
dropped from a height of 90 cm (3 ft) or
more.

• Check sensor for dents, cracks or deformation.
• Check sensor connector (sensor side and harness
side) and sensor connector lock mechanism for
damage or crack.
• Check connector terminals for bend, corrosion or rust.

21) Wash your hands with mild soap and water
afterward.
NOTE
Remaining steps are to be followed in the
unlikely event that air bag (inflator) module
did not deploy or seat belt pretensioner did
not activate.

22) Ensure that deployment harness has been
disconnected from 12 volts vehicle battery and that
its two banana plugs have been shorted together by
fully seating one banana plug into the other.
23) Disconnect deployment harness and adapter cable
from air bag (inflator) module or seat belt
pretensioner.
24) Temporarily store undeployed air bag (inflator)
module referring to “Precautions on Service and
Diagnosis of Air Bag System” for details.
25) Contact your local distributor for further assistance.
Deployment / Activation Inside of Vehicle
When the vehicle will be destroyed, or salvaged for
component parts, deploy the air bag modules and/or
activate seat belt pretensioners installed on vehicle.
NOTE
If equipped with the seat belt pretensioners,
activate both side of seat belt pretensioners
at the same time when using special tool (C).

1) Turn ignition switch to LOCK position, remove key
and put on safety glasses.
2) Remove all loose objects from front seats and
instrument panel.
3) Disconnect air bag (inflator) module or seat belt
pretensioner connector as follows.
• For driver air bag (inflator) module [A]
Remove driver side front pillar lower trim and
disconnect driver air bag (inflator) module
connector (1).
• For passenger air bag (inflator) module [B]
Remove passenger side front pillar lower trim and
disconnect passenger air bag (inflator) module
connector (2).
• For side-air bag (inflator) module [C]
Disconnect side-air bag (inflator) module
connectors (3) under front seat cushion.
• For side curtain-air bag (inflator) module [D]
Remove right-side rear quarter lower trim and
disconnect side curtain-air bag (inflator) module
connector (4).
• For seat belt pretensioners (right and left) [E]
Remove both side (driver and passenger side)
center pillar lower trim and disconnect seat belt
pretensioner connectors (5).4) Confirm that each air bag (inflator) module and/or
seat belt pretensioners is securely mounted.
