Downloaded from www.Manualslib.com manuals search engine Air Bag System: 8B-104
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.
