TROUBLESHOOTING
LHEADLIGHT
OPERATION

lTurn the lighting switch to “HEAD”, and the con-
tact point of the headlight relay will be closedto turn “ON” the headlight relay.
lWhen the dimmer switch is placed in the LO
position, the headlight low-beams go on. On
vehicles up to 1993 model, when the switch
is placed in the HI position, the headlight high-
beams go on. On vehicles from 1994 model,when the switch is placed in the HI position,
the headlight high-beams and low-beams go
on.
l
When the high-beam is lit or when the passing
switch is activated, the high-beam indicator lightwill be lit.
l
If the driver’s door is opened after the ignition
switch is turned to “OFF” or the ignition switchis turned to “OFF” after the driver’s door is
opened when the headlights are lit, the currentwhich flows to the coil side of the headlight
relay will be cut off by the light automatic shut-OFF unit opening the contact point, and the
headlight relay will be turned “OFF” to automati-
cally shut off the headlights.l
To turn the headlights on again after they are
automatically shut off, turn the lighting switchto “OFF” once and then back to “HEAD”, or
turn the ignition switch to “ACC” or “ON”, and
the
aut0mati.c shut-OFF will be cancelled andthe current will flow from the light automatic
shut-OFF unit to the coil side of the headlightrelay again to close the contact point. Thus,
the headlight relay will be turned “ON” to turnon the headlights.
NOTEWhen the lighting switch is at “HEAD”, the light
automatic shut-OFF system is valid for tail lights,
parking and side marker lights, license plate light,
illumination light, etc.(Refer to
P.54-70.)
(Up to 1993 models)by lighting
l
When the lighting switch is placed in the HEAD
position, current flows through multi-purpose
fuse (6) to the lighting switch, and the ETACScontrol unit. Then the UP timer circuit in the
LETACS control unit is operated, and currentflows from the ETACS control unit to the U con-tact of the pop-up motor U/D (UP/DOWN)
switch, the coil of the pop-up motor relay and
ground, causing the contacts of the pop-up mo-
tor relay to close.
When the contacts of the pop-up motor relay
close, current flows through the contacts of the
pop-up motor relay to the pop-up motor and
ground, causing the pop-up motor to rotate,
which brings the headlights to the UP position.
The pop-up motor rotates until the automatic
UP stop position is reached, then the contactsof the interlocked U/D (UP/DOWN) switch
change from the U to D contacts. As a result,
the contacts of the pop-up motor relay opento cut off the current supplied to the pop-up
motor. Then the pop-up motor ceases to rotate,
holding the headlights in the UP position.l
When the lighting switch is placed in the TAIL
or OFF position, current flows through the multi-
purpose fuse (6) to the lighting switch, and the
ETACS control unit. Then the DOWN timer cir-
cuit in the ETACS control unit is operated and
current flows from the ETACS control unit to
the DOWN contacts of the pop-up motor U/D
(UP/DOWN) switch, the coil of the pop-up motor
relay and ground, causing the contacts of the
pop-up motor relay to close.
When the contacts of the pop-up motor relay
close, current flows through the contacts of the
pop-up motor relay to the pop-up motor andground, causing the pop-up motor to rotate,
which brings the headlights to the DOWN posi-
tion.
The pop-up motor rotates until the automatic
DOWN stop position is reached, then the con-
tacts of the interlocked U/D (UP/DOWN) switch
change from the D to U contacts. As a result,
the contacts of the pop-up motor relay open
to cut off current supply to the pop-up motor.
Then the pop-up motor ceases to rotate, holding
the headlights in the DOWN position.
switch> (Up to 1993 models)by POPUPl
When the pop-up switch is placed in the UP
position, current flows through multi-purpose
fuse (6) to the lighting switch, the pop-up switch
and the ETACS control unit, which brings the
headlights to the UP position and holds them
in the UP position just like when they are oper-
ated by the lighting switch.l
When the pop-up switch is placed in the DOWN
position, current flows through the multi-purpose
fuse (6) to the lighting switch, the pop-up switch
and the ETACS control unit, which brings the
headlights to the DOWN position and holds them
in the DOWN position just like when they are
operated by the lighting switch.

OPERATION
lWhen the fog light switch is placed in the ON position with the lighting switch in the HEAD positionand the dimmer switch in the LO position, current flows through the dedicated fuse (4) to the coil
of the fog light relay, the fog light switch, the dimmer switch and ground, causing the contacts of
the fog light relay to close.
When the contacts of the fog light relay close, current flows through the dedicated fuse (4) to the
contacts of the fog light relay, the fog lights and ground, causing the fog lights to come on.
lWhen the dimmer switch is placed in the HI position or the lighting switch is placed in the TAIL or
OFF position while the fog lights are ON, current supply to the fog light relay or headlight relay is
cut off. As a result, the contacts of the fog light relay open, and the fog lights go out.
NOTE
The fog lights are included in the light automatic shut-OFF system. (Refer to P.54-37). The indicator lights
are also included in the same system.

OPERATION
0When the lighting switch is placed in the TAILor HEAD position, current flows through the
coil of the tail light relay to the lighting switchand ground, causing the contacts of the tail
light relay to close.
Then current flows through the contacts of thetail light relay to the dedicated fuse
(2) the
individual lights and ground, causing the tail
lights, parking/side marker lights and licenseplate lights to go ON.

lIf the driver’s door is opened after the ignition
switch is turned to “OFF” or the ignition switchis turned to “OFF” after the driver’s door is
opened when the tail lights are lit, the current
which flows to the coil side of the tail light relaywill be cut off by the light automatic shut-off
unit opening the contact point, and the tail light
relay will be turned “OFF’ to automatically shut
off the tail lights, parking and front side marker
lights and license plate light.
lTo turn on the tail lights, parking and front side
marker lights and license plate light again after
they are automatically shut off, turn the lightingswitch to “OFF” once and to “HEAD” again,
or turn the ignition switch to “ACC” or “ON”,
and the automatic shut-OFF will be cancelled
and the current will flow from the light automaticshut-OFF unit to the coil side of the tail light
relay to close the contact point. Thus, the taillight relay will be turned “ON” to turn on the
tail lights, parking and front marker lights and
license plate light.
NOTE
When the lighting switch is at the “HEAD” position,
the light automatic shut-OFF system will be also
activated for the headlights. (Refer to P.54-37.) The
same system will also be activated for the illumina-
tion lights, etc.
TROUBLESHOOTING HINTS1. All lights don’t illuminate.
(1) The headlights don’t illuminate, either.l Check the fusible link (3).
(2) The headlights illuminate.l Check the tail light relay. (Refer to
P.54-108.)l Check the dedicated fuse (2).
l Check the lighting switch. (Refer to
P.54-113.)l Check the light automatic shut-OFF
unit. (Refer to
P.54-108.)2. Some light does not come on.
l Check the bulb.
l Check the grounding circuit.
3. Some light is not automatically shut off.
lCheck the driver’s side door switch.
(Refer to GROUP 42- Door Assembly.)l Check the automatic shut-OFF unit.
