(1) Connect the scan tool to the data link connector located
at the right side of the junction block or connect the voltme-
ter between the ETACS terminal and the ground terminal.
(2) Check if the buzzer of the scan tool sounds or the needle
of the voltmeter moves when each switch is operated.
If the buzzer sounds or the needle moves, the input signalsare being input to the ETACS unit, so that switch can
be considered to be functioning normally. If not, the switch

OPERATION light>l
Battery voltage is always applied to the dome light. When the dome light switch is turned to “ON”,
the dome light will remain lit. After either door is opened if the dome light switch is at “DOOR” position,the dome light will come on.
lWith the dome light turned on (with the ignition switch in the OFF position and with the dome light
switch in the DOOR position), close all doors, and the timer circuit in the ETACS unit will be activatedto gradually vary the voltage for approx. 6 seconds owing to the duty control, and the voltage will
be output to transistor Tr. Since the voltage applied to the dome light gradually decreases, the dome
light will be dimmed.lIf the ignition switch is turned to “ON” while the dome light is lit (while the timer is activated), the
timer circuit will be opened to turn “OFF” transistor Tr. This will immediately turn off the dome light
without dimming. light>-lBattery voltage is always applied to the foot lights and ignition key illumination light.
With the ignition switch in the OFF position, open any door, and all lights will come on.
l
With all lights turned on (with the ignition switch in the OFF position), close all doors, and the timercircuit inside the ETACS unit will operate in the same manner as the dome light to dim all lights.
When the ignition switch is placed in the ON position with all lights turned on (with the timer in operation),the same operation as the dome light will take place.

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

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
