WINDSHIELD WIPER AND WASHER
OPERATION
Windshield Low-speed (and High-speed)
Wiper Operation
•If the windshield low-speed wiper switch is turned
to the ON position with the ignition switch at the
"ACC" or "ON" position, the column switch sends
a low-speed wiper ON and high-speed wiper OFF
signals to the front-ECU. This turns the wiper sig
-
nal on and the wiper speed control relay off
(low-speed), causing the wipers to operate at
low-speed.
•If the windshield high-speed wiper switch is
turned to the ON position, the column switch
sends a low-speed wiper OFF and high-speed
wiper ON signals to the front-ECU. This turns
both the wiper signal and the wiper speed control
relay on (high-speed), causing the wipers to
operate at high-speed.
NOTE: The windshield wiper speed is switchable
with the built-in wiper speed control relay.
High-speed operations take place when the wiper
speed control relay is set to "ON" and low-speed
operations take place when the wiper speed control
relay is set to "OFF".
Windshield Intermittent Wiper Operation
The ETACS-ECU calculates the wiper operation
interval according to the voltage signal sent from the
column switch. Then the ETACS-ECU sends a signal
to the front-ECU. The front-ECU determines the
wiper operation interval and turns on the wiper relay
signal relay. This causes the wiper auto stop relay to
turn on. Then the wiper auto stop relay will turn off
after the wipers reach the park position. This causes
the wiper signal relay and then the wipers to turn off.
If the wiper signal relay remains off for the wiper
operation interval, the relay turns on again, causing
the wipers to operate in intermittent mode.
Windshield Mist Wiper Operation
•If the windshield mist wipe r switch is turned to the
ON position with the ignition switch at the "ACC"
or "ON" position, the mist wiper high-speed oper
-
ation signal is sent to the front-ECU. This signal
turns on the wiper speed control relay, causing
the wipers to work at high-speed while the mist
switch is on.
•While the windshield mist wiper switch remains
turned on when the intermittent mode is still work
-
ing, the wipers work as the mist wiper. However,
the wipers return to the intermittent mode again
when the switch is changed back to "INT" posi
-
tion.
•To prevent the windshield mist wiper from operat-
ing when the windshield wiper switch is turned
OFF, the windshield mist wiper does not work for
0.5 second after the windshi eld intermittent wiper
switch, the windshield low-speed wiper switch
and the windshield high-speed wiper switch are
turned OFF.
Windshield Washer Operation
•If the windshield washer switch is turned to ON
position with the ignition sw itch at "ACC" or "ON"
position, the windshield wa sher ON signal is sent
to the front-ECU. After 0.3 second, the windshield
wiper signal turns on. After the windshield washer
switch signal turns off, the windshield wiper signal
turns off in three seconds.
•If the windshield washer switch is turned on while
the windshield wiper is at intermittent mode,
when the windshield washer switch is turned OFF
within 0.2 second, the wiper works only once to
perform mist operation by the windshield washer
switch. When the ON condi tion of the windshield
washer switch continues more than 0.2 second,
the wiper performs the same movement as nor
-
mal condition from the time when 0.2 second has
elapsed and then returns to the intermittent
motion.

DOOR MIRROR OPERATION
Remote Controlled Mirror Operation
•The mirror on the door mirror moves up/down
and left/right by operating the remote controlled
door mirror switch when the ignition switch is in
the "ON" or "ACC" position.
Heated Door Mirror operation
•The defogger relay switch is activated (ON) by
turning on the A/C-ECU built-in defogger switch
when the ignition switch is in the "ON" position.
When the defogger relay is turned ON, power is
supplied to the defogger and door mirror, and the
heater of the door mirror (heated door mirror)
starts operations. The defogger comes with a
timer function and will automatically turn OFF the
switch approximately 11 minutes after the defog
-
ger switch is turned ON. The heated door mirror
operations are also terminated along with the
defogger, at this time.
