AIRBAG SYSTEM (DIAGNOSTICS)
2. WITHOUT DTC
DETECTING CONDITION:
•Defective combination meter
•Open circuit of harness
TROUBLE SYMPTOM:
•Airbag warning light remains on.
•“NO TROUBLE CODE” will be displayed on the Subaru Select Monitor.
For detailed operation procedure, refer to “Airbag Warning Light Failure”. <Ref. to AB(diag)-40, Airbag Warn-
ing Light Failure.>
NOTE:

nector (AB6)?
If the poor contact
of the connector is
not fixed, replace
the airbag main
harness with body
harness or replace
the airbag control
module. <Ref. to
AB-21, Airbag
Control Module.>
Go to step 3.
3CHECK AIRBAG MAIN HARNESS.
1) Remove the instrument panel lower cover
and disconnect the connectors (AB7) and
(AB2).
2) Remove the console side cover lower on
the passenger's side and disconnect the con-
nectors (AB10) and (AB9).
3) Disconnect the connector (AB6) from air-
bag control module, and connect the connector
(1U) in the test harness U.
4) Connect the battery ground terminal and
turn the ignition switch to ON.
5) Connect the connectors (7U) and (8U) in
the test harness U.
NOTE:After the fault has been cleared, disconnect the
connectors (7U) and (8U).
Does the airbag warning light
go off?
Go to step 4.Go to step 5.
4CHECK GROUND CIRCUIT.
1) Turn the ignition switch to OFF, disconnect
the battery ground cable, and wait more than
20 seconds.
2) Disconnect the connector (AB6) from air-
bag control module.
3) Connect the connector (1U) in the test har-
ness U to body harness connector (AB6).
4) Measure the resistance between connector
(2U) in the test harness U and chassis ground.
Connector & terminal
(2U) No. 10 — Chassis ground:
(2U) No. 11 — Chassis ground:
Is the resistance less than 10
Ω?
Replace the airbag
control module.
<Ref. to AB-21,
Airbag Control
Module.>
Repair the chas-
sis ground circuit.
5CHECK AIRBAG MAIN HARNESS AND
BULKHEAD HARNESS.
1) Disconnect the connectors (7U) and (8U).
2) Remove the combination meter.
3) Measure the resistance between connector
(i11) and connector (2U) in the test harness U.
Connector & terminal
(2U) No. 7 — (i11) No. 12:
Is the resistance less than 10
Ω?
Check the combi-
nation meter.
Go to step 6.

Basic Diagnostic Procedure
WIRING SYSTEM
•Each connector number shown in the wiring dia-
gram corresponds to that in the wiring harness. The
location of each connector in the actual vehicle is
determined by reading the first character of the
connector (for example, a “F” for F8, “i” for i16, etc. )
and the type of wiring harness. The first character
of each connector number corresponds to the area
or system of the vehicle.
