When the ignition switch is at the ACC or ON posi-
tion, if the windshield mist wiper switch of the column
switch is turned ON, the front-ECU turns ON the
windshield wiper drive signal. At the same time, the
wiper speed switching relay is turned ON (HIGH-
SPEED). While the windshield mist wiper switch is
ON, the windshield wiper will operate at high speed.
Then, if the windshield mist wiper switch is turned off,
the wiper operates at low speed until it stops at the
predetermined park position.
