WINDSHIELD WIPER AND WASHER

CONSTRUCTION DIAGRAM

2-speed (low/high speed) windshield wiper has been adopted.
The intermittent wiper features a vehicle speed-dependent variable intermittent time system*.
Wiper motor torque has been increased to improve kinetic performance of the wiper in the snowfall. Wiper blade pressure has been increased to improve the wiping performance while driving at high speed.
The mist wiper is turned ON by operating the mist switch in the opposite direction of the wiper switch for easy operation. The mist wiper is equipped with the function that quickly wipes raindrops away at high speed when the mist switch is ON, and when the mist switch is OFF, at low speed until the stop position is reached. When the mist switch is briefly turned ON, the wiper operates once at low speed.
The windshield washer is a 2-nozzle and 4-jet type.
Washer nozzle with the integral check valve has been adopted to prevent the washer fluid from running down, and to improve the response to switch operation.
The washer motor for both of a windshield washer motor and a rear washer motor has been installed to reduce the weight.
Washer-linked wiper function* has been adopted. The washer fluid can be injected without operating the wiper. When the ignition switch is turned ON while the washer switch is ON, the washer motor operates but the wiper does not.

note

*: Using the customisation function, the vehicle speed-dependent variable intermittent time system and the washer-linked wiper function can be adjusted (Refer to

DESCRIPTION OF CONSTRUCTION AND OPERATION

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

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 communication).

note Using the customisation function, the vehicle speed-dependent intermittent function can be invalidated (Refer to ).
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 windshield 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 operation 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.

Windshield wiper linked with washer function <Initial condition: with function, with windshield washer check valve>

Wiper switch	OFF position			Intermittent operation position				Low-speed or high-speed operation position
Washer switch ON time	0.3 second or less	0.3 to 0.5 second	0.5 second or more	0.2 second or less	0.2 to 0.4 second	0.4 to 0.6 second	0.6 second or more	-
Intermittent wiper time (T)	0 second	2 seconds	3 seconds	0 second	1 second	2 seconds	3 seconds	3 seconds

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 conditions. 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 intermittently, 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 customisation function, the washer linked windshield wiper function can be invalidated (Refer to ).
Using the customisation function, when the washer linked windshield wiper function is invalidated, only the washer operates. It is useful to melt down the ices of the frozen windshield.
