M1549021500075
The following ECUs affect the functions and control
of the windshield wiper and washer.
Windshield wiper and washer control function
.
Intermittent control
The ETACS-ECU calculates the intermittent time from the
windshield wiper intermittent time adjusting knob at the column
switch and sends it to the front-ECU as SWS data.
The front-ECU determines the intermittent time T1 from the
input SWS data signal, and turns ON the windshield wiper drive
signal. When the wiper is at the STOP position, the windshield
wiper auto-stop signal goes OFF to turn OFF the windshield
wipe drive signal. After the intermittent time T1 seconds from
when the windshield wiper drive signal turned ON, the wind-
shield wiper drive signal is turned ON again and the above
operation is repeated.
.
Mist wiper control
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.
When the windshield mist switch is turned on briefly,
the wiper operates at low speed once.
At the point the windshield mist switch is turned ON,
if the windshield wiper has been operating intermit-
tently, the same operations as the above will be per-
formed while the windshield mist wiper switch is ON.
After the windshield mist wiper switch goes OFF, the
intermittent operations will be set again T1 seconds
after the windshield wiper auto-stop signal is turned
ON last.
