SEAT BELT SYSTEM
Seat Belt Warning System
14 CHECK HARNESS BETWEEN TCU AND
SEAT BELT TIMER MODULE.
Measure the resistance between seat belt
timer module harness connector and chassis
ground.
Connector & terminal
(B44) No. 7 — Chassis ground:Is the resistance less than 10
Ω?Go to step 15.Repair the short of
harness.
15 CHECK SEAT BELT TIMER MODULE OUT-
PUT SIGNAL.
1) Turn the ignition switch to ON.
2) Measure the voltage between seat belt
timer module harness connector and chassis
ground.
Connector & terminal
(B44) No. 2 (+) — Chassis ground (–):Is the voltage more than 10 V? Go to step 16.Check the wiring
harness and com-
bination meter,
and then repair or
replace them.
16 CHECK POOR CONTACT.
Check the poor contact of seat belt warning
light circuit.Is there any poor contact
occurs?Repair the poor
contact.Go to step 17.
17 CHECK SEAT BELT TIMER MODULE.
1) Connect all connectors.
2) Lift-up the vehicle and place rigid racks.
NOTE:
Raise all wheels off floor.
3) Hold the tang plate disconnected from seat
belt buckle.
4) Start the engine, and set the vehicle speed
less than 19 km/h (12 MPH)
N
OTE:
The speed difference between front and rear
wheels may light the ABS warning light, but this
indicates no malfunction. When diagnosis is fin-
ished, perform the ABS memory clearance pro-
cedure of OBD system. Memory Mode.>
Check seat belt warning light comes on.Does the seat belt warning
light come on?Go to step 18.Replace the seat
belt timer module.
18 CHECK SEAT BELT TIMER MODULE.
1) Connect all connectors.
2) Lift-up the vehicle and place rigid racks.
N
OTE:
Raise all wheels off floor.
3) Hold the tang plate disconnected from seat
belt buckle.
4) Start the engine, and set the vehicle speed
more than 25 km/h (16 MPH).
NOTE:
The speed difference between front and rear
wheels may light the ABS warning light, but this
indicates no malfunction. When diagnosis is fin-
ished, perform the ABS memory clearance pro-
cedure of OBD system. Memory Mode.>
Check seat belt warning light comes on and
buzzer beeps.Does the seat belt warning
light come on and buzzer
beep?Temporary poor
contact of connec-
tor or harness may
be the cause.
Check the poor
contact.Replace the seat
belt timer module. Step Check Yes No
