1) Disconnect the connector (i84) from body
integrated unit.
2) Turn the ignition switch to ON.
3) Measure the voltage between body inte-
grated unit connector and chassis ground.
Connector & terminal
(i84) No. 1 (+) — Chassis ground (–):
Is the voltage more than 10 V? Go to step 3.Repair the har-
ness for open or
shorted circuit
between body inte-
grated unit and
fuse.
3CHECK POOR CONTACT OF CONNECTOR.Is there poor contact in body
integrated unit connector?
Repair the poor
contact of connec-
tor.
Go to step 4.
4CHECK BODY INTEGRATED UNIT HAR-
NESS.
1) Connect all the connectors.
2) Perform the clear memory mode.
3) Read DTC.

1 CHECK POOR CONTACT OF CONNEC-
TORS.
Check for poor contact of the connectors
between the occupant detection control mod-
ule and belt tension sensor.
Is there poor contact? Reconnect the
connector. If the
fault is not fixed,
replace the airbag
harness.
Go to step 2.
2CHECK THE BELT TENSION SENSOR.
1) Turn the ignition switch to OFF, disconnect
the battery ground cable, and wait more than
20 seconds.
2) Disconnect the belt tension sensor connec-
tor (AB56) from the airbag harness.
3) Connect the test harness AC to the con-
nector (AB56).
4) Connect the battery ground terminal and
turn the ignition switch to ON.
Does the airbag warning light
illuminate for approximately 6
seconds and go off?
Replace the seat
belt outer. SB-10, REMOVAL,
