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,

3 CHECK THE AIRBAG HARNESS.
1) Turn the ignition switch to OFF, disconnect
the battery ground cable, and wait more than
20 seconds.
2) Disconnect the test harness AC from the
belt tension sensor connector (AB56).
3) Connect the test harness AD (1AD) to the
connector (AB56).
4) Disconnect the airbag harness connector
(AB61), and connect the connector (1AB) in
test harness AB.
5) Measure the resistance between test har-
ness terminals.

(2AB) No. 4 — (2AD) No. 3:
(2AB) No. 6 — (2AD) No. 2:
Is the resistance less than 10
Ω?
Go to step 4.Replace the airbag
harness with chas-
sis harness.
4 CHECK THE AIRBAG HARNESS.
Measure the resistance between test harness
terminals, and between test harness terminal
and chassis ground.

(2AB) No. 5 — chassis ground:
Is the resistance more than 1
MΩ?
Go to step 5.Replace the airbag
harness with chas-
sis harness.
5 CHECK THE AIRBAG HARNESS.
1) Connect the battery ground terminal and
turn the ignition switch to ON.
2) Measure the voltage between test harness
and chassis ground.
Connector & terminal
(2AD) No. 1 — chassis ground:
(2AD) No. 3 — chassis ground:
Is the voltage less than 1 V? Replace the airbag
harness with chas-
sis harness.
Check the seat
harness, and if any
fault is found,
replace the seat
harness. If no fault
is found in the seat
harness, replace
the seat cushion
frame assembly.
