ENABLING/DISABLING THE HAZARD
ANSWERBACK FUNCTION
The hazard answerback function can be enabled or
disabled by one of the two following procedures.
1. Enter the hazard answerback customize mode by performing one of the following steps. If the
ETACS-ECU enters the customize mode, its
buzzer will sound once.
(1) Turn the ignition switch to “LOCK”(OFF) position.
(2) Turn off the hazard warning lamp switch.
CAUTION
Before connecting or disconnecting the earth,
turn the ignition switch to the "LOCK" (OFF)
position.

(4) Close the driver's side door.
(5) Keep the windshield washer switch on for at least ten seconds. Then the ETACS-ECU
buzzer will sound once.
2. If the transmitter “LOCK” button is pushed consecutively twice (wit hin two seconds), the
ETACS-ECU buzzer will sound, indicating that the
hazard answerback function can be enabled or
disabled when the doors are locked.
WINDSHIELD WIPER AND WASHER

WINDSHIELD WIPER AND WASHER
GENERAL INFORMATIONM1511000100514
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.
