1. When operation is normal
l
When the ignition switch is switched to the
ON position, battery voltage is applied (via
the 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
l
If the LH (or RH) turn-signal light bulb is
burned-out, the resistance of the turn-signal
circuit as a whole increases, resulting in
L
shorter ON and OFF intervals of the LH
Trl (or RH Tr2) and a higher flashing rate
of the LH lights (or RH lights).

OPERATION
<Hazard-warning lights,
l When the hazard-warning switch is switch-
ed to the “ON” position, the relay contact
of the turn signal and hazard flasher unit
is switched ON and OFF repeatedly, in the
same 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 lights
do 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-
l Check 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 light
shut-OFF system, refer to P.54-37.
