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.
7) Use the Subaru Select Monitor to check whether
the driver’s seat position sensor and the front left/
right seat belt buckle switches are operating nor-
mally.
B: INSPECTION
If the vehicle is involved in a collision on any side,
even if it is a slight collision, be sure to check the
following systems.
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) Occupant detection system and seat cushion
pad
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 the following. If necessary, install a new air-
bag module and steering wheel.
• 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 17 mm (0.67 in)
L
A
2. SIDE COLLISION
1) Airbag control module
2) Side airbag module (operating side seat back)
3) Side 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 connector of airbag module, preten-
sioner, etc. for damage, and also check each har-
ness for pinch and connector damage. Replace the
harness as a unit if damage is found.
3) Check the seat cushion frame, backrest, seat rail
and headrest for deformation, distortion, crack, and
installing condition and play.
4) If deformation or cracks are seen in the seat
cushion frame of the passenger’s seat, replace the
occupant detection system.
5) If there are tears or loosening in the passenger’s
seat cushion cover, it may interfere with the proper
operation of the occupant detection system. Re-
place with a new cushion cover.
6) If the seat cushion cover is removed or replaced,
make sure to perform occupant detection system
adjustment after installing the seat. <Ref. to OD(di-
ag)-17, SYSTEM CALIBRATION (REZEROING),
OPERATION, Subaru Select Monitor.>
Failure to do so may cause improper activation of
passenger’s airbag.

2. PASSENGER’S AIRBAG MODULE
Check for the following, and replace the damaged
parts with new parts.
• Airbag module is cracked or deformed.
• Harness and/or connector is cracked, deformed
or open. Harness wire is exposed.
• Mounting bracket is cracked or deformed.

8. STEERING SHAFT
Check for the following, and replace the damaged
parts with new parts.
• Overall length of steering column should be with-
in specification.
Specification:
Overall length L
808.6
±
1.5 mm (31.83
±

2) After checking the installing condition of passen-
ger’s seat, perform the system calibration of occu-
pant detection system. <Ref. to OD(diag)-17,
SYSTEM CALIBRATION (REZEROING), OPERA-
TION, Subaru Select Monitor.>
11.BELT TENSION SENSOR
Check for the following, and replace the damaged
parts with new parts.

semble.
• Cracks or deformation is found in the seat
