OPERATION
When the lighting switch is placed in the TAIL
or HEAD position, current flows through the
coil of the tail light relay to the lighting switch
and ground, causing the contacts of the tail
light relay to close.
Then current flows through the contacts of the
tail light relay to the dedicated fuse (2) the
individual lights and ground, causing the tail
lights, parking/side marker lights and license
plate lights to go ON.
If the driver's door is opened after the ignition
l
switch is turned to "OFF" or the ignition switch
is 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 relay
will 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.
To turn on the tail lights, parking and front side
l
marker lights and license plate light again after
they are automatically shut off, turn the lighting
switch 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 automatic
shut-OFF unit to the coil side of the tail light
relay to close the contact point. Thus, the tail
light 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.
