WINDSHIELD WIPER AND WASHER

GENERAL DESCRIPTION

M1511000100558

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 adjustable
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 wiper 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 windshield 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 the

ON position with the ignition switch at "ACC" or
"ON" position, the windshield washer ON signal is
sent to the front-ECU. After 0.3 second, the wind-
shield 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, and
the windshield washer switch is turned OFF
within 0.2 second, the wiper works only once to
perform mist operation. When the windshield
washer switch is turned on for more than 0.2 sec-
ond, the wiper performs the same movement as
normal condition from the time when 0.2 second
has elapsed, and then returns to intermittent
operation.

WINDSHIELD WIPER AND WASHER DIAGNOSIS

M1511000700389

The windshield wiper and washer are controlled by
the Simplified Wiring System (SWS). For trouble-
shooting, refer to GROUP 54B, SWS Diagnosis

P.54B-10

.

NOTE: Even when the ETACS-ECU has failed, the
windshield wiper can work at low speed as fail-safe
mode. (Normally, the windshield wiper operates
when the ignition switch is at the "ACC" position. But,
if it enters the fail-safe mode, the wiper can operate
only when the ignition switch is at the "ON" position.)
