3. Inspection Locations after a

Collision

A: REPLACEMENT

Replace the following parts if the airbag has been

activated.

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 passenger detection sys-

tem. 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)-14, SYS-

TEM

CALIBRATION

(REZEROING),

OPERATION, Subaru Select Monitor.>

7) Use the Subaru Select Monitor to check whether

the front right 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 (deflection of steering

wheel)

Less than 6 mm (0.24 in)

Vertical deflection L (runout of steering

wheel)

Less than 17 mm (0.68 in)
