NOSIS MODE.
1) Turn the ignition switch to OFF.
2) Start the engine while pressing defroster
switch and A/C switch.

OTE:
Self-diagnosis can also be performed with the
ignition switch ON, but start the engine be-
cause telling the magnet clutch operation is dif-
ficult.

2 CHECK LED ILLUMINATION.
Make sure that three LED blink in turn on A/C
control panel (5 patterns are repeated 2 times).Do all LED blink? Go to step 3.Go to step 5.
3 CHECK SENSORS MALFUNCTION.
1) After completing the LED check or when
AUTO switch is pressed, the A/C switch LED
illuminates, and then the sensor check is
started.
2) Check the input signal of each sensor in
turn. If there are any trouble for each sensor,
DEF, MODE and fan speed LEDs are blinked.
Also check for each sensor is possible respec-
tively every time AUTO switch is pressed. (At
this time, the AUTO switch LED illuminates.)
3) If there is no trouble, DEF, MODE and fan
speed LEDs are turned off.
N
OTE:
Rear window defogger LED illuminates in case
of stored malfunction but does not illuminate in
case of present malfunction.Does each DEF, MODE and
fan speed LED turn off?Go to step 4.Confirm the com-
bination of illumi-
nating LEDs by
using Sensor
Check Table, and
identify the mal-
functioning sensor
before repairing.

4 CHECK OPERATION OF EACH ACTUATOR,
COMPRESSOR AND FAN MOTOR.
1) Press the FRESH/RECIRC switch
(FRESH/RECIRC switch LED illuminates at
this time.).
2) Refer to OPERATING MODE TABLE to
check the operation of each actuator, compres-
sor and fan motor. ING MODE TABLE, OPERATION, Diagnostic
Chart for Self-Diagnosis.>
Also check for each step is possible respec-
tively every time AUTO switch pressed. (At this
time, the AUTO switch LED illuminates.)Does each actuator, compres-
sor and fan motor operate
according to operating mode
table?Press the OFF
switch or turn the
ignition switch to
OFF and finish the
self-diagnosis
mode.Refer to each
diagnostics chart
for actuator, com-
pressor and fan
motor, and repair
the malfunctioning
par t as necessary.

5 CHECK POOR CONTACT.
Check the auto A/C control module connector
for poor contact.Is there a poor contact in con-
nector?Replace the auto
A/C control mod-
ule.Repair the con-
nector.

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
