Airbag Warning Light Failure
AIRBAG SYSTEM (DIAGNOSTICS)
Step Check Yes No
1 READ DTC.
Read the DTC. <Ref. to AB(diag)-32, READ
DIAGNOSTIC TROUBLE CODE (DTC),
OPERATION, Subaru Select Monitor.>
Is DTC displayed? Perform the diag-
nosis according to
DTC. Go to step 2 .
2 CHECK POOR CONTACT.
1) Turn the ignition switch to OFF, disconnect
the battery ground cable, and wait more than 20
seconds.
2) Confirm that there is solid connection
between the airbag control module and connec-
tor (AB6).
Is there poor contact in connec-
tor (AB6)? If the poor contact
of the connector is
not fixed, replace
the airbag main
harness along with
body harness or
replace the airbag
control module.
<Ref. to AB-19,
Airbag Control
Module.> Go to step 3 .
3 CHECK 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 connec-
tors (AB10) and (AB9).
3) Disconnect the connector (AB6) from the
airbag control module, and connect the connec-
tor (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).

4 CHECK 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 airbag
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-19,
Airbag Control
Module.> Repair the chassis
ground circuit.
5 CHECK 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 .
6 CHECK POOR CONTACT OF CONNECTORS
(AB) AND (B31).
1) Turn the ignition switch to OFF, disconnect
the battery ground terminal, and wait more than
20 seconds.
2) Confirm that there is a firm contact between
connectors (AB) and (B31).
Is there poor contact between
connectors (AB) and (B31)? Repair the bulk-
head harness or
replace the airbag
main harness
along with body
harness. Go to step 7 .
