1) How to disconnect:
Holding outer part (A), pull it in the direction of ar-
row.
CAUTION:
When pulling the slide lock or disconnecting
connector, be sure to hold the connector, not
the harness.

•Outer side (A) move back, and so do not put
your hand on the outer part.
•Be sure to insert the connector in until it is
locked. Then pull it gently to make sure that it is
locked.

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.
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)

General Description
AIRBAG SYSTEM (DIAGNOSTICS)
•The removed front seat with airbag module must
be kept at least 200 mm (8 in) away from walls and
other objects.
•When painting or performing sheet metal work
on the front part of the vehicle, including the front
wheel apron, front fender and front side frame, re-
move the front sub sensors and wire harness of air-
bag system.
•When painting or performing sheet metal work
on the side of the vehicle, including the side sill,
center pillar and front and rear doors, remove the
side airbag sensors and wire harness of the airbag
system.
•Do not discard undeployed airbag module. They
could easily cause a serious accident if accidentally
deployed.

Step Check Yes No
1CHECK POOR CONTACT OF CONNEC-
TORS.
Check for poor contact of the connectors
between the airbag control module and the
occupant detection control module.
Is there poor contact? Reconnect the
connector. If
defective is not
improved, replace
the airbag rear
harness RH or the
occupant detection
harness (seat har-
ness).
Go to step 2.
2CHECK THE AIRBAG HARNESS.
1) Turn the ignition switch to OFF, disconnect
the battery ground cable, and wait more than
20 seconds.
2) Disconnect the connector (AB18) from air-
bag control module.
3) Disconnect the connectors (AB59) and
(AB61) under the passenger's seat.
4) Connect the connector (1U) in the test har-
ness U to connector (AB18).
5) Connect the connector (1AB) in the test
harness AB to the connector (AB61).
6) Measure the resistance between connector
(3U) in the test harness U and connector (2AB)
in the test harness AB.
Connector & terminal
(3U) No. 2 — (2AB) No. 1:
(3U) No. 4 — (2AB) No. 2:
Is the resistance less than 10
Ω?
Go to step 3.Replace the airbag
rear harness RH
with body harness.
3CHECK THE AIRBAG HARNESS.
Measure the resistance between connector
(3U) in the test harness U and chassis ground.
Connector & terminal
(3U) No. 2 — Chassis ground:
(3U) No. 2 — (3U) No.4:
Is the resistance less than 10
Ω?
Go to step 4.Replace the airbag
rear harness RH
with the body har-
ness.
4CHECK THE AIRBAG HARNESS.
1) Turn the ignition switch to ON.
2) Measure the voltage between connector
(2AB) in the test harness AB and chassis
ground.
Connector & terminal
(2AB) No. 3 — chassis ground:
Is the voltage more than 9 V? Go to step 5.Check the battery
voltage and fuse. If
there is no faulty,
replace the airbag
rear harness RH
with body harness.

5CHECK THE AIRBAG HARNESS.
Measure the voltage between connector (2AB)
in the test harness AB and chassis ground.
Connector & terminal
(2AB) No. 1 — chassis ground:
Is the voltage more than 9 V? Replace the airbag
rear harness RH
with body harness.
Replace the occu-
pant detection har-
ness (seat
harness). If defec-
tive is not
improved, replace
the occupant
detection system
(seat cushion &
frame assembly),
and then the air-
bag control mod-
ule in this order.

T: DTC 36 SEAT POSITION SENSOR LH FAILURE
DTC DETECTING CONDITION:
•Driver's seat position sensor is faulty.
•Airbag control module is faulty.
•Airbag rear harness LH circuit is open, shorted or shorted to ground.
CAUTION:
•Before diagnosing the airbag system, be sure to turn the ignition switch to OFF, disconnect the
ground terminal from battery, and wait more than 20 seconds before starting to work.
•After replacing the airbag module, seat belt pretensioner, roll connector, control module and sen-
sor, reconnect each part and confirm that the warning light operates properly.
•When inspecting the airbag harness, disconnect the each airbag module connector, and seat belt
pretensioner for safety reasons.
