Inspection Locations After a Collision

AIRBAG SYSTEM

3. Inspection Locations After a 

Collision

A: REPLACEMENT

Replace the following parts when the airbag is de-
ployed.

1. FRONT COLLISION

1) Driver’s airbag module
2) Passenger’s airbag module
3) Driver’s seat belt (Pretensioner)
4) Passenger’s seat belt (Pretensioner)
5) Airbag control module
6) Front sub sensor (L/R)
7) Roll connector
8) Instrument panel (for integrating with passen-
ger’s airbag module)
9) Passenger’s side seat cushion pad and frame
assembly

2. SIDE COLLISION

1) Airbag control module
2) Satellite safing sensor
3) Side airbag module (operating side seat back-
rest)
4) Side airbag sensor (operating side)
5) Curtain airbag module (operating side)
6) Curtain airbag sensor (operating side)
7) Satellite safing sensor mounting bracket and
cover

3. INSPECTION OF OTHER PARTS

Check for the following parts, and replace the dam-
aged parts with new parts.
1) Steering wheel and steering shaft
Check the steering shaft for mounting conditions
and deflection of front and rear, upward and down-
ward directions, and deflection of front and rear di-
rection with tilt lever released. (After a collision,
absorbing part of steering shaft may have been op-
erated.)
2) Check the direct type connector of drivers airbag
module, curtain airbag module and pretensioner,
etc. for damage, and also check each harness for
pinch and connector damage. Replace the harness
as a unit if damage is found.
3) Check the seat cushion frame, backrest, slide
rail and headrest for deformation, distortion, crack,
and installing condition and play.
4) For the passenger’s seat, replace the seat cush-
ion pad and frame assembly with a new part if the
seat cushion pad and frame assembly is deformed
or cracked.

5) If there are tears or loosening in the passenger
side seat cushion cover, it may interfere with the
proper operation of the occupant detection system.
Replace with a new cushion cover.
6) Be sure to perform the system calibration for the
occupant detection system after removing or re-
placing the passenger seat cushion cover. Failure
to do so may cause improper operation of the occu-
pant detection system. <Ref. to OD(diag)-15, SYS-
TEM CALIBRATION (REZEROING),
OPERATION, Subaru Select Monitor.>
7) Use the Subaru Select Monitor to check whether
the passenger’s seat belt buckle switch is operating
normally.

B: INSPECTION

If the vehicle is involved in a collision, even if it is a
slight collision, be sure to check the following sys-

or open. Harness wire is exposed.
• The module surface is fouled with grease, oil,
water or cleaning solvent.
2) When installing a new driver’s airbag module,
check for the following, and replace the damaged
parts with new parts.
• The steering wheel is in the way, making it diffi-
cult to install the airbag module.
• The clearance between the driver’s airbag mod-
ule and steering wheel is not constant.
• When steering wheel deformation in axial and
vertical directions exceed limits.

Specification:

Axial deflection A

Less than 6 mm (0.24 in)

Vertical deflection L

Less than 15 mm (0.59 in)
