OPERATION
1. When operation is normal
l
When the ignition switch is switched to the
ON position, battery voltage is applied (via
L,
the multi-purpose fuse @ and hazard switch)
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
shorter ON and OFF intervals of the LH Trl
(or RH
Tr2)
and a higher flashing rate of the
LH lights (or RH lights).

<Hazard-warning lights>
l
When the hazard-warning switch is switched 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-warning
lights does not change if there is damaged 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.8-315.)
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 normally.
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
(hazard-
warning light side).
