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
7) Roll connector
8) Passenger's side seat cushion pad and frame
assembly
9) Instrument panel (for integrating with passen-
ger's airbag module)
2. SIDE COLLISION
1) Airbag control module
2) Satellite safing sensor
3) Satellite safing sensor cover
4) Side airbag module (operating side seat back-
rest)
5) Side airbag sensor (operating side)
6) Curtain airbag module (operating side)
7) Curtain airbag sensor (operating side)
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 driver's air-
bag module, curtain airbag module, pretensioner,
etc. for damage, and also check each harness for
pinch and connector damage. Replace the main
harness as a unit if damage is found.
3) Check the seat cushion, backrest, seat rail and
headrest for installing condition and play.
4) For the passenger's seat, replace the seat cush-
ion pad frame assembly with a new part if the seat
cushion 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. If sys-
tem adjustment is not performed, the occupant
detection system may not function properly. <Ref.
to OD(diag)-15, SYSTEM CALIBRATION (REZE-
ROING), 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-
tems.
1. DRIVER'S AIRBAG MODULE
1) Check for the following, and replace the dam-
aged parts with new parts.
• Airbag module is cracked or deformed.
• Harness and/or connector is cracked, deformed
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.
Standard:
Axial deflection A
Less than 6 mm (0.24 in)
Vertical deflection L
Less than 17 mm (0.68 in)
