out.
1) Prepare the Subaru Select Monitor kit.
TOOL, General Description.>
2) Connect the diagnosis cable to Subaru Select
Monitor.
3) Insert the cartridge to Subaru Select Monitor.
4) Connect the Subaru Select Monitor to data link
connector.
(1) Data link connector (1) is located in the low-
er portion of instrument panel (on the driver’s
side).
(2) Connect the diagnosis cable to data link
connector.
CAUTION:
Do not connect the scan tools except for Suba-
ru Select Monitor.
5) Turn the ignition switch to ON (engine OFF) and
turn the Subaru Select Monitor switch to ON.
6) On the «Main Menu» display screen, select the
{Each System Check} and press the [YES] key.
7) On the «System Selection Menu» display
screen, select the {Airbag System} and press the
[YES] key.
8) {Press the [YES] key after the {**MY AIRBAG
SYSTEM} is displayed.
9) On the «Airbag System» screen, select the
{DTC Display}, and then press the [YES] key.

Step Check Yes No
1CHECK POOR CONTACT OF CONNEC-
TORS.
Check for poor contact of the connectors
between the airbag control module and the
driver's airbag module.
Is there poor contact? Replace the airbag
harness.
Go to step 2.
2CHECK DRIVER'S AIRBAG MODULE.
1) Turn the ignition switch to OFF, disconnect
the battery ground cable, and wait more than
20 seconds.
2) Remove the driver’s airbag module.
3) Connect the connector (AB38) to the con-
nector (1N) in the test harness N.
4) Connect the airbag resistor to the connec-
tor (2N) of test harness N.
5) Connect the connector (1Q) in the test har-
ness Q to connector (AB37).
6) Connect the airbag resistor to the connec-
tor (2Q) of test harness Q.
7) Connect the battery ground terminal and
turn the ignition switch to ON.
Does the airbag warning light
illuminate for 6 seconds and go
off?
Replace the
driver's airbag
module.

Go to step 3.
3CHECK ROLL CONNECTOR.
1) Turn the ignition switch to OFF, disconnect
the battery ground cable, and wait more than
20 seconds.
2) Disconnect the test harness N from con-
nector (AB38).
3) Disconnect the test harness Q from con-
nector (AB37).
4) Remove the instrument panel lower cover
and disconnect the connector (AB7) from
(AB2).
5) Connect the connector (1P) in the test har-
ness P to connector (AB2).
6) Connect the airbag resistor to the connec-
tors (2P) and (3P) of test harness P.
7) Connect the battery ground terminal and
turn the ignition switch to ON.
Does the airbag warning light
illuminate for 6 seconds and go
off?

Go to step 4.
4CHECK AIRBAG MAIN HARNESS (DRIV-
ER'S AIRBAG HARNESS).
1) Turn the ignition switch to OFF, disconnect
the battery ground cable, and wait more than
20 seconds.
2) Disconnect the airbag resistor from the
connectors (2P) and (3P) of test harness P.
3) Remove the console side cover lower on
the passenger's side and disconnect the con-
nectors (AB10) and (AB9).
4) Disconnect the connector (AB6) from air-
bag control module, and connect the connector
(1U) in the test harness U.
5) Connect the battery ground terminal and
turn the ignition switch to ON. (Engine OFF)
6) Measure the voltage between connector
(2U) in the test harness U and chassis ground.
