(Approx. 0.1 second after
inserting the key)
Is the voltage 0 V?
(Approx. 1 second after insert-
ing the key)Go to step 7.Replace the IMM
ECM 37, Immobilizer
Control Module.>
and then replace
all ignition keys
(including the tran-
sponder). Then

undergone the teaching operation, furnished
with vehicle.Does the engine start? Replace the igni-
tion key (including
the transponder).
Then perform

tion manual (Pub.
No. S0820GZ).Replace the IMM
ECM 37, Immobilizer
Control Module.>
and then replace

PRECAUTION
Precaution
1. Precaution
A: PRECAUTION
Please clearly understand and adhere to the follow-
ing general precautions. They must be strictly fol-
lowed to avoid minor or serious injury to the person
doing the work or people in the area.
1. ABS
Handle the ABS as a total system. Do not disas-
semble or attempt to repair individual parts. Doing
so could prevent the ABS system from operating
when needed or cause it to operate incorrectly and
result in injury.
2. BRAKE FLUID
If brake fluid gets in your eyes or on your skin, do
the following:
 Wash out your eyes and seek immediate medical
attention.
 Wash your skin with soap and then rinse thor-
oughly with water.
3. RADIATOR FAN
The radiator fan may rotate without warning, even
when the engine is not on. Do not place your hand,
cloth, tools, or other items near the fan at any time.
4. ROAD TESTS
Always conduct road tests in accordance with traf-
fic rules and regulations to avoid bodily injury and
interrupting traffic.
5. AIRBAG
To prevent bodily injury from unexpected deploy-
ment of airbags and unnecessary maintenance, fol-
low the instructions in this manual when performing
maintenance on airbag components or nearby, and
airbag wiring harnesses or nearby.
To prevent unexpected deployment, perform the
steps below and then wait at least 20 seconds to
discharge electricity before beginning work.
 Step 1: Turn the ignition switch OFF.
 Step 2: Disconnect the ground cable from bat-
tery.
6. AIRBAG DISPOSAL
To prevent bodily injury from unexpected airbag
deployment, do not dispose airbag modules in the
same way as other refuse. Follow all government
regulations concerning disposal of refuse.
7. AIRBAG MODULE
Adhere to the following when handling and storing
the airbag module to prevent bodily injury from un-
expected deployment:
 Do not hold the harnesses or connectors to carry
module.
 Do not face the bag in the direction that it opens
towards yourself or other people.
 Do not face the bag in the direction that it opens
towards the floor or walls.
8. AIRBAG SPECIAL TOOLS
To prevent unexpected deployment, only use spe-
cial tools.
9. WINDOW
Always wear safety glasses when working around
any glass to prevent glass fragments from damag-
ing your eyes.
10.WINDOW ADHESIVE
Always use the recommended or alternative adhe-
sive when attaching glass to prevent it from coming
loose and falling, resulting in accidents and injury.

10.FRONT HOOD STAY INSTALLATION
 At the check and general maintenance
 When wider hood opening is necessary
Set stay into the hole of hood inner as shown in the figure below.
NOTE:
Before setting the front hood in this position, remove the windshield washer hose attaching clip from the front
hood.
11.TRAINING
For information about training, contact a dealer or
agent.
12.GENERAL SCAN TOOL
Using general scan tools will greatly improve effi-
ciency of repairing engine electronic controls. The
Subaru Select Monitor can be used to diagnose the
engine and also the ABS, the air conditioner, and
other parts.
