1
CHECK SIDE AIRBAG MODULE.
1) Turn the ignition switch OFF, disconnect the
battery ground cable, and wait more than 20
seconds.
2) Disconnect the connector (AB20) from
(AB19), and connect the connector (1F) in test
harness F to connector (AB19).
3) Connect the airbag resistor to connector
(3F) in the test harness F.
4) Connect the battery ground cable and turn
the ignition switch to ON.
Does the airbag warning light
illuminate for 6 seconds and go
off?
Replace the side
airbag module
(LH). <Ref. to AB-
18, REMOVAL,
Side Airbag Mod-
ule.>
Go to step 2.
2
CHECK AIRBAG REAR HARNESS (SIDE
AIRBAG MODULE HARNESS LH).
1) Turn the ignition switch OFF, disconnect the
battery ground cable, and wait more than 20
seconds.
2) Disconnect the connector (AB21) from seat
belt pretensioner (LH).
3) Disconnect the connector (AB31) from cur-
tain airbag module (LH).
4) Disconnect the airbag resistor from test
harness.
5) Disconnect the connector (AB17) from air-
bag control module.
6) Connect the connector (1U) in the test har-
ness U to connector (AB17).
7) Measure the resistance between connector
(3U) in the test harness U and connector (3F)
in the test harness F.
Connector & terminal
(3U) No. 12 — (3F) No. 4:
(3U) No. 10 — (3F) No. 3:
Is the resistance less than 10
Ω?
Go to step 3.
Replace the airbag
rear harness with
body harness.
3
CHECK AIRBAG REAR HARNESS (SIDE
AIRBAG MODULE HARNESS LH).
Measure the resistance between connector
(3U) terminals in the test harness U.
Connector & terminal
(3U) No. 12 — (3U) No. 10:
Is the resistance more than 1
M
Ω?
Go to step 4.
Replace the airbag
rear harness with
body harness.
4
CHECK AIRBAG REAR HARNESS (SIDE
AIRBAG MODULE HARNESS LH).
Measure the resistance between connector
(3U) in the test harness U and chassis ground.
Connector & terminal
(3U) No. 12 — Chassis ground:
(3U) No. 10 — Chassis ground:
Is the resistance more than 1
M
Ω?
Replace the airbag
control module.
<Ref. to AB-22,
Airbag Control
Module.>
Replace the airbag
rear harness with
body harness.
