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.
