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 drive signal
(the wiper drive signal 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 configuration function, the washer linked
windshield wiper function can be turned off. (Refer
to P.51-13.)
⦆
Using the configuration function, when the washer
linked windshield wiper function is turned off, only
the washer operates. It is useful to melt down ice on
a frozen windshield.
