GENERAL INFORMATION

WINDSHIELD WIPER AND WASHER OPERATION

.

Intermittent control (Vehicle speed-dependent
variable type) <Initial condition: with function>

1. ETACS calculates the windshield intermittent wiper interval

T1 from the position of the windshield intermittent wiper
switch on the column switch and the vehicle speed signal
(sent from the combination meter to ETACS via CAN com-
munication).
NOTE: Using the configuration function, the vehicle
speed-dependent intermittent function can be invalidated
(Refer to

P.51-65

).

2. When ETACS receives the ON signal of the windshield

intermittent wiper switch, it turns the windshield wiper relay
ON. When the wiper reaches the stop position, the wind-
shield wiper auto-stop signal turns OFF, and the windshield
wiper relay turns OFF.
When the intermittent time T1 calculated by step 1 has
elapsed after the windshield wiper relay ON, the windshield
wiper relay turns ON again, and the above-mentioned oper-
ation is repeated.

.

Mist wiper control

When the windshield wiper mist switch on the column switch is
turned ON while the ignition switch is in ACC or ON position,
the column switch turns the windshield wiper relay ON. At the
same time, the wiper speed switching relay turns ON (HI).
When the windshield mist wiper switch is ON, the windshield
wiper operates at high speed.

Low speed wiper and high speed wiper control

When the windshield low speed wiper switch on the
column switch is turned ON while the ignition switch
is in ACC or ON position, the column switch turns the
windshield wiper relay ON. Also, the wiper speed
switching relay turns OFF (LO), and the windshield
wiper operates at low speed.

When the windshield high speed wiper switch is
turned ON, the windshield wiper relay turns ON.
Also, the wiper speed switching relay turns ON (HI),
and the windshield wiper operates at high speed.

When the windshield washer switch on the column
switch is turned ON while the ignition switch is in
ACC or ON position, ETACS turns the windshield
washer relay ON.
When the windshield washer switch is kept ON for
0.3 seconds or longer, the windshield wiper relay (the
wiper relay output time varies depending on the con-
ditions. For details, see the table.) is turned ON, and
the windshield wiper operates at high speed. The
windshield wiper is turned OFF with 3 seconds delay
after the windshield washer switch is turned OFF.
Even when the windshield washer switch is turned
ON while the windshield wiper is operating intermit-
tently, the intermittent action starts again after the
linked operation is finished.

If the ignition switch is turned to ACC position while
the windshield washer switch is ON, the windshield
washer relay turns ON, but the windshield wiper
does not perform the linked operation. When the
windshield washer switch is turned OFF and then
ON, the windshield wiper starts the linked operation.
NOTE:

.

•

Using the configuration function, the washer
linked windshield wiper function can be invali-
dated (Refer to

P.51-65

).

•

Using the configuration function, when the
washer linked windshield wiper function is invali-
dated, only the washer operates. It is useful to
melt down the ices of the frozen windshield.

.

Rain sensitive wiper function

<Optional: Vehicles for USA with lighting control sensor (rain sensor)>

• Lighting control sensor (rain sensor) has been

installed in the upper part of the windshield to
sense the raindrops and windshield wiper can be
operated when the ignition switch is at ON and
wiper switch is at AUTO position.

• The lighting control sensor detects the raindrops

on the windshield surface using the optical ele-
ment, and it automatically switches the wind-
shield wiper operation, depending on the amount
of rainfall, to the intermittent or LO/HI operation.

• The lighting control sensor detects the raindrops

using the reflections of infrared rays, and
depending on the amount of rainfall, it automati-
cally adjusts the wiping speed.

• Dry windshield: All infrared rays emitted from the

emitter diode are reflected by the windshield and
directed to the receiver diode as they are.

• Wet windshield: Part of the infrared rays emitted

from the emitter diode are transmitted to outside
of the windshield through the raindrops, and the
infrared rays with reduced intensity are directed
to the receiver diode.

NOTE: Using the configuration function, the rain sen-
sitive wiper function can be invalidated (Refer to

P.51-65

).
