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.
