AIRBAG SYSTEM (DIAGNOSTICS)
2
CHECK AIRBAG REAR HARNESS (BE-
TWEEN SIDE AIRBAG SENSOR (RH) AND
CURTAIN AIRBAG SENSOR (RH)).
1) Turn the ignition switch to OFF, disconnect
the battery ground cable, and wait for 60 sec-
onds or more.
2) Disconnect the connector (AB26) from seat
belt pretensioner (RH).
3) Disconnect the connector (AB33) from cur-
tain airbag module (RH).
4) Disconnect connector (AB24) of the side
airbag module (RH).
5) Disconnect connector (AB28) from side air-
bag sensor (RH).
6) Connect the connector (AB28) of side air-
bag sensor (RH) and the connector (1AI) in the
test harness AI.
7) Connect the connector (2AI) in the test har-
ness AI and the connector (1V) in the test har-
ness V.
8) Disconnect the connector (AB34) from cur-
tain airbag sensor (RH), and connect the con-
nector (2V) in test harness V to connector
(AB34).
9) Measure the resistance between connector
(3V) terminals in the test harness V.
Connector & terminal
(3V) No. 2 — (3V) No. 6:
(3V) No. 1 — (3V) No. 7:
Is the resistance less than 10
Ω?
Go to step
3.
Replace the airbag
rear harness along
with body harness.

CHECK AIRBAG REAR HARNESS (BE-
TWEEN SIDE AIRBAG SENSOR AND CUR-
TAIN AIRBAG SENSOR RH).
Measure the resistance between connector
(3V) in test harness V and chassis ground, and
the resistance between connector (3V) in test
harness V.
Connector & terminal
(3V) No. 2 — Chassis ground:
(3V) No. 1 — Chassis ground:
(3V) No. 2 — (3V) No. 1:
Is the resistance 1 MΩ or
more?
Go to step
4.
Replace the airbag
rear harness along
with body harness.
