When hazard warning switch is “OFF”, Yellow lead @ is connected to Yellow/Blue lead 0.
When the hazard warning switch is “ON”,White/Green lead @I is connected to Yellow/Blue lead @I, and
Green lead (12)to both Green/Yellow lead @ and Green/Red lead @.
When Turn-signal switch is “ON” for right turn, Green lead @ is connected to Green/Yellow lead @.
When Turn-signal switch is “ON” for left turn, Green lead @ is connected to Green/Red lead @.

INSPECTION
1) Trouble diagnosis
Symptom
1. Lights will not come on in either left or
right group of light.
2. Hazard light comes on but turn signal
lights will not.
3. No light comes on; or lights light up but
do not flicker.
4. Turn signal lights are satisfactory, but
hazard light will not come on.
5. Flickering freueqncy is erratic, or lights
remain lit.
6. Turning on hazard warning switch lights up
only one group of lights.
2) Turn signal switch
Using circuit tester, check for continuity
between each pair of terminals by referring to
the chart given below and figure at the right
for each position of turn signal switch lever.
Discontinuity means that contact points are
burnt or otherwise defective in the switch.
For example, switch is in sound condition if
continuity is noted between terminals 2 and
3, with lever in right-turn position, and
between terminals 1 and 3, with lever in left-
turn position.
Possible cause
Fusible link is blown off.
Open circuit (due to poor point contact) in turn
signal dimmer switch.
Defective relay unit.
Open circuit in hazard warning switch.
Light bulbs are defective or improperly grounded.
Defective contact in dimmer switch.

3) Hazard warning switch
Disconnect, lead wire of the hazard warning switch at its coupler. Set switch to ON position and check
for continuity with circuit tester between each of the following pairs of terminals; 2 and 3, 1 and 3, 5
and 6 among those shown in Fig. 21-10. The switch is in sound condition if continuity is noted between
each pair.

21-9. 4 WHEEL DRIVE LAMP21-10. SEAT BELT WARNING LAMP/
BUZZERThe 4 wheel drive lamp circuit consists of the 4
wheel drive indicator lamp switch installed to
the transfer and the lamp inside the combination
meter.
The 4WD switch so operates that it is switched
ON when transfer gear shift control lever is
shifted to “4H” or “4L” position.
The seat belt warning lamp/buzzer circuit is a
system to light and sound the lamp and buzzer
respectively for several seconds, urging the
driver to wear his seat belt. After several seconds
passed, the lamp goes OFF and the buzzer stops
sounding whether the seat belt is worn or not.
