Basic Diagnostic Procedure
AIRBAG SYSTEM (DIAGNOSTICS)
1. Basic Diagnostic Procedure
A: PROCEDURE
Step Check Yes No
1CHECK WARNING LIGHT.
Check whether the airbag warning light in the
combination meter is lit.
Does the airbag warning light
illuminate?
Go to step 2.Perform the diag-
nosis according to
phenomenon of
the problem.
2READ DTC.
1) Turn the ignition switch to OFF.
2) Connect the Subaru Select Monitor to data
link connector.
3) Turn the ignition switch to ON, and the Sub-
aru Select Monitor power switch to ON.
4) Read the DTC.
OPERATION, Read Diagnostic Trouble Code
(DTC).>
NOTE:If the communication function of the Subaru Se-
lect Monitor cannot be executed normally,
check the communication circuit.
AB(diag)-33, COMMUNICATION FOR INI-
TIALIZING IMPOSSIBLE, INSPECTION, Sub-
aru Select Monitor.>
5) Record all DTCs and freeze frame data.
Is DTC displayed? Go to step 3.

ing Light Fail-
ure.>Go to “Airbag
Wa r ni n g L ig h t Fa i l-
ure”.
3PERFORM DIAGNOSIS.
1) Judge the possible cause from “List of
Diagnostic Trouble Code”
45, List of Diagnostic Trouble Code (DTC).>.
2) Inspect the DTC using “List of Diagnostic
Tr o u b l e C o d e ( D T C ) ” .
3) Repair the trouble cause.
4) Perform the clear memory mode.

General Description
AIRBAG SYSTEM (DIAGNOSTICS)
3. General Description
A: CAUTION
•When servicing a vehicle, be sure to turn the ig-
nition switch to OFF, disconnect the ground cable
from battery, and wait for more than 20 seconds
before starting work.
•The airbag system is fitted with a backup power
source. After disconnecting the battery ground ca-
ble, the airbag may deploy if you do not wait for
more than 20 seconds before starting the service of
airbag system.
•If sensors, airbag module, airbag control module,
pretensioner or harness is deformed or damaged,
replace with new part.
•Do not use the airbag system and pretensioners
on other vehicles. When replacing parts, be sure to
replace them with new ones.
•When checking the airbag system, be sure to
use a digital circuit tester. Use of an analog circuit
tester may cause the airbag to activate erroneously
due to a minimal current inside tester.
•When checking, use a test harness (1). Damage
to connector terminal causes malfunction. Do not
directly put the tester probe on airbag connector
terminal.
•Do not drop the airbag system parts, or keep
them at high temperature over 93°C (199°F), or let
water, oil or grease get on them; the internal parts
may be damaged and reliability greatly lowered.

General Description
AIRBAG SYSTEM (DIAGNOSTICS)
•If damage, open circuit or rust is found on airbag
system wire harness, do not use a soldering equip-
ment to repair. Replace the faulty harness with a
new genuine part.
•Install the wire harness securely with the speci-
fied clips to avoid interference or tangled with other
parts.
•Do not allow water or oil to come in contact with
the connector terminals. Also do not touch the con-
nector terminals.
•Either of the airbag modules for driver’s, passen-
ger’s, side or curtain, or the pretensioner must not
be disassembled.
•The airbag module cannot be used again if de-
ployed once.
•After removal, keep the airbag module with the
pad side facing upward on a dry, clean and flat sur-
face away from heat, light sources, moisture and
dust.
•Do not check continuity of the airbag modules for
driver’s side, passenger’s side and curtain, or the
pretensioner.
