SWS -General Information54B-4
WINDSHIELD WIPER AND WASHER
Windshield Low-speed/High-speed Wiper
Operation
DIf the windshield low-speed wiper switch is
turned to the ON position with the ignition switch
at the ACC or ON position, the column switch
sends a low-speed wiper ON and high-speed
wiper OFF signals to the front-ECU.
This turns the wiper signal on and the wiper
speed switching relay off (low-speed), causing
the wipers to operate at low-speed.
DIf the windshield high-speed wiper switch is
turned to the ON position, the column switch
sends a low-speed wiper OFF and high-speed
wiper ON signals to the front-ECU.
This turns both the wiper signal and the wiper
speed switching relay on (high-speed), causing
the wipers to operate at high-speed.
Windshield Intermittent Wiper Operation
The ETACS-ECU calculates the wiper operation
interval according to the voltage signal sent from the
column switch. Then the ETACS-ECU sends a
signal to the front-ECU. The front-ECU determines
the wiper operation interval and turns on the wiper
signal relay. This causes the wiper auto stop relay to
turn on. Then the wiper auto stop relay will turn off
after the wipers reach the park position. This causes
the wiper signal relay and then the wipers to turn off.
If the wiper signal relay remains off for the wiper
operation interval, the relay turns on again, causing
the wipers to operate in intermittent mode.Windshield Mist Wiper Operation
DIf the windshield mist wiper switch of the column
switch is turned to the ON position with the
ignition switch at ACC or ON position, the mist
wiper high-speed operation signal is sent to
the front-ECU. This signal turns on the wiper
speed switching relay, causing the wipers to
work at high-speed while the mist switch is
on.
DWhile the windshield mist wiper switch remains
turned on when the intermittent mode is still
working, the wipers work as the mist wiper.
However, the wipers return to the intermittent
mode again when the wiper auto stop signal
turns on after the mist wiper switch is turned
off.
Windshield Washer Operation
If the windshield washer switch of the column switch
is turned to the ON position with the ignition switch
at ACC or ON position, the windshield washer ON
signal is sent to the front-ECU, causing the
windshield wiper signal to turn on after 0.3 seconds.
After the windshield washer switch signal turns off,
the windshield wiper signal turns off in three
seconds.
If the windshield wiper switch is turned to the ON
position while the windshield wiper is at intermittent
mode, the windshield washer works for that period
when the windshield washer switch remains on.
Then the wipers return to the intermittent mode.
REAR WIPER AND WASHER
Rear Wiper Operation
If the rear wiper switch is turned to the ON position
with the ignition switch at ACC or ON position,
the ETACS-ECU turns ON the rear wiper drive signal
for three seconds (approx. two operations). 7.4
seconds later, the wiper begins the intermittent
operation with 8 seconds’ cycle.
If the shift lever or selector lever is
moved to the R position when the rear wiper switch
is turned to the ON position and the ignition switch
at ACC or ON position, back-up lamp switch
or inhibitor switch R turns ON. One second
later, the ETACS-ECU turns ON the rear wiper drive
signal for three seconds (approx. two operations)
to clear the rear field of view. 7.4 seconds later,
the wiper returns to the intermittent operation with
8 seconds’ cycle.Rear Washer Operation
If the rear washer switch is turned to the ON position
with the ignition switch at ACC or ON position,
the rear washer ON signal is sent to the
ETACS-ECU, causing the rear wiper signal to turn
on after 0.3 seconds. After the rear washer switch
signal turns off, the rear wiper signal turns off in
three seconds.
If the rear wiper is in intermittent operation when
the rear washer switch is turned ON, the rear wiper
again continues the intermittent operation with 8
seconds’ cycle from 7.4 seconds later since the
rear drive signal is turned OFF.
