General Description
AIRBAG SYSTEM
•Do not discard the uninflated airbag or preten-
sioner.
•When airbag control module, front sub sensor,
side airbag sensor and curtain airbag sensor are
removed, do not reuse the bolts and nuts of them.
Always use new bolts and nuts for them.
•Do not drop each airbag module, airbag control
module and each sensor, or store these parts un-
der high temperature over 93°C (199°F), or let wa-
ter, oil or grease get on them; the internal parts may
be damaged or the reliability may be greatly low-
ered.
•After removal of each parts for airbag system,
keep them with the pad facing upward on a dry,
clean and flat surface without heat, light sources,
moisture and dust.
•The airbag modules for driver’s, passenger’s,
side or curtain, or the pretensioner must not be dis-
assembled.
•When performing attachment of the steering
wheel and steering roll connector, make sure to
perform adjustment of the steering roll connector.
•The removed front seat with airbag module must
be kept at least 200 mm (8 in) away from walls and
other objects.

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 side seat cushion pad and frame as-
sembly
2. SIDE COLLISION
1) Airbag control module
2) Side airbag module (operating side seat back-
rest)
3) Side airbag sensor (operating side)
4) Curtain airbag module (operating side)
5) 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,
there is a good chance that the shock absorbing
part of steering shaft may have operated.)
2) Check the connectors 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) For passengers seat, replace the seat cushion
frame assembly with new one if the seat cushion
frame 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 pas-
senger detection system.
TION, Subaru Select Monitor.>
7) Use the Subaru Select Monitor to check whether
the drivers seat position sensor and the drivers and
the front left/right seat belt buckle switches are op-
erating 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.
Specification:
Axial deflection A
Less than 6 mm (0.24 in)
Vertical deflection L
Less than 7 mm (0.28 in)
