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.

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

General Description
SEAT BELT SYSTEM
B: CAUTION
•Before starting the work, turn the ignition switch
to OFF, disconnect the battery ground cable and
wait for 20 seconds or more.
•The pretensioner system has a backup power
source. The pretensioner might deploy if you do not
wait for 20 seconds or more before starting work.
•Do not drop or apply any impact to the preten-
sioner.
•If oil, grease or water gets on the pretensioner,
wipe it off immediately with a dry cloth.
•Do not expose the pretensioner to high tempera-
ture or flame.
•Do not allow current to flow through or voltage to
reach the pretensioner. Do not use a circuit tester
to check resistance of the pretensioner.
•Do not disassemble or attempt to repair the pre-
tensioner. If it is dented, cracked or deformed, re-
place it with a new one.
•Do not use the airbag or pretensioner parts from
other vehicles. Always replace parts with new
parts.
•When handling a seat belt with deployed preten-
sioner, wear gloves and goggles. Wash your hands
afterwards.
•Do not reuse a seat belt with deployed preten-
sioner.
•If material from the airbag enters the eyes or con-
tacts skin during deployment, wash it away with
clean water, and then consult a doctor.
