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.
(Refer to
P.54-108.)

OPERATIONl
Battery voltage is always applied (via sub-fusiblelink No. (6) and multipurpose fuse No. (19))
to the luggage compartment light and door light.l
When the door is opened, the door switch is
switched ON and the door light illuminates.l When the
liftgate is opened, the luggage
compartment light switch is switched ON and
the luggage compartment light illuminates.GLOVE BOX LIGHT, VANITY MIRROR LIGHT AND INSPECTION LIGHT
OPERATIONl
When the lighting switch is.placed in the TAIL
or HEAD position, and the contacts of the tail
light relay close, battery voltage is applied viathe dedicated fuse (2) to the glove box light,
the vanity mirror light and the inspection light.l
When the glove box is opened, the glove box
illumination light switch is switched ON and the
glove box illumination light illuminates.l
When the vanity mirror lid is opened, the vanity
mirror light switch is switched ON and the vanity
mirror light illuminates.l
When the engine hood is opened, the inspection
light switch is switched ON and the inspection
light illuminates.
NOTE
The light automatic shut-off system is valid for theglove box light, vanity mirror light and inspection
light. (Refer to
P.54-37.)

Downloaded from www.Manualslib.com manuals search engine 1. When operation is normal
l
When the ignition switch is switched to the
ON position, battery voltage is applied (viathe multipurpose fuse (11) and hazard
switch) to the turn-signal and hazard flasher
unit.l
When the turn-signal switch is switched to
the LH position,
Trl (within the flasher unit)
is switched ON and OFF repeatedly.
Then the contacts of the relay 1 (also within
the flasher unit) repeatedly switch from ON
to OFF, causing the turn-signal lights and
turn-signal indicator light LH to flash.l
When the turn-signal switch is switched to
the RH position, Tr2 (within the flasher unit)
is switched ON and OFF repeatedly.Then the contacts of relay 2 (also within
the flasher unit) repeatedly switch from ON
to OFF, causing the turn-signal lights and
turn-signal indicator light RH to flash.2. If one of the bulbs is burned out
lIf the LH (or RH) turn-signal light bulb is
burned-out, the resistance of the turn-signalcircuit as a whole increases, resulting in
Lshorter ON and OFF intervals of the LHTrl (or RH Tr2) and a higher flashing rateof the LH lights (or RH lights).CHASSIS ELECTRICAL

TURN-SIGNAL LIGHT AND HAZARD
L
LIGHT
OPERATION
lWhen the hazard-warning switch is switch-
ed to the “ON” position, the relay contactof the turn signal and hazard flasher unit
is switched ON and OFF repeatedly, in thesame manner as for the operation of the
turn-signal lights, and the left and right turn-
signal lights and turn-signal indicator lights
simultaneously flash repeatedly.
NOTE
(1) The number of flashes of the hazard-warn-
ing lights does not change if there is dam-
aged or disconnected wiring of one light.
(2)The light automatic shut-OFF system is valid
for the illumination light of the hazard switch.(Refer to
P.54-37.)
TROUBLESHOOTING HINTS
1.The turn-signal lights and hazard-warning lightsdo not operate at all.
l Check the hazard switch contact (power
supply side).l Check the turn-signal and hazard flasher
unit.2. All turn-signal lights at the left (or right) side
do not function.
(1) The hazard-warning lights function normal-
ly-lCheck the hazard switch contact (turn-
signal side).l Check the turn-signal switch.
3.The number of flashes of the turn-signal lights
is excessive.l Check the bulbs.
4. The hazard-warning lights do not function.
(1) The turn-signal lights function normally.l
Check the hazard switch contact (haz-
ard-warning light side).
NOTE
For the troubleshooting hints of the automatic lightshut-OFF system, refer to
P.54-37.
