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.

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.
