CHECK AIRBAG REAR HARNESS (BE-
TWEEN AIRBAG CONTROL MODULE AND
SIDE AIRBAG SENSOR LH).
1) Disconnect the connectors (AB6, AB17,
AB18) from airbag control module.
2) Connect the connector (1AH) in the test har-
ness AH to the connectors (AB17, AB6, AB18).
3) Connect the connector (2AH) in the test har-
ness AH and the connector (1AG) in the test
harness AG.
4) Disconnect the connector (AB23) in the side
airbag sensor (LH) from the connector (1AI) in
the test harness AI.
5) Disconnect the connector (2AI) in the test
harness AI from the connector (1V) in the test
harness V.
6) Connect the connector (2V) in the test har-
ness V to the connector (AB23).
7) Measure the resistance between connector
(5AG) in the test harness AG and connector
(3V) in the test harness V.
Connector & terminal
(5AG) No. 9 — (3V) No. 2:
(5AG) No. 10 — (3V) No. 1:
Is the resistance less than 10
Ω?
Go to step
5.
Replace the airbag
rear harness along
with body harness.

CHECK AIRBAG REAR HARNESS (BE-
TWEEN SIDE AIRBAG SENSOR LH AND
CURTAIN AIRBAG SENSOR LH).
Measure the resistance between connector
(3V) in test harness V and chassis ground, and
the resistance between connector (5AG) termi-
nals in test harness AG.
Connector & terminal
(5AG) No. 9 — Chassis ground:
(5AG) No. 10 — Chassis ground:
(5AG) No. 9 — (5AG) No. 10:
Is the resistance 1 MΩ or
more?
Go to step
6.
Replace the airbag
rear harness along
with body harness.

CHECK AIRBAG CONTROL MODULE.
1) Connect all connectors.
2) Clear the memory.
3) Perform the Inspection Mode.
4) Read the DTC.
Is the same DTC displayed?
Go to step
7.
Go to step
8.

REPLACE SIDE AIRBAG SENSOR (LH) AND
CHECK AIRBAG CONTROL MODULE AF-
TER REPLACEMENT.
1) Turn the ignition switch to OFF, disconnect
the battery ground cable, and wait for 60 sec-
onds or more.
2) Replace the side airbag sensor (LH). <Ref.
to AB-23, REMOVAL, Side Airbag Sensor.>
3) Connect all connectors.
4) Clear the memory.
5) Perform the Inspection Mode.
6) Read the DTC.
Is the system normal?
Go to step
8.
Replace the cur-
tain airbag sensor
(LH). <Ref. to AB-
24, REMOVAL,
Curtain Airbag
Sensor.> Replace
the airbag control
module if not oper-
ating normally
even after replac-
ing the sensor.
<Ref. to AB-21,
REMOVAL, Airbag
Control Module.>
