Low speed wiper and high speed wiper
control

When the windshield low speed wiper switch of the
column switch is turned ON while the ignition switch
is ACC or ON, the column switch turns ON the
windshield wiper drive signal. Also, the wiper speed
switching relay turns to OFF (LO), and the windshield
wiper operates at the low speed.

When the windshield high speed wiper switch is
turned ON, the windshield wiper drive signal turns
ON. Also, the wiper speed switching relay turns ON
(HI), and the windshield wiper operates at the high
speed.

GENERAL INFORMATION

SMART WIRING SYSTEM (SWS) NOT USING SWS MONITOR

54B-14

• When the front-ECU receives a windshield

washer switch signal from the column switch with
the ignition switch in the ACC or the ON position,
the ECU turns on the windshield washer relay.
When the windshield washer relay becomes ON,
the windshield washer motor starts to run to
spray the washer fluid in the washer tank onto the
windshield through the washer nozzles. When
the windshield washer switch signal remains on
for 0.3 seconds or more, the signal turns on the
windshield wiper relay (The wiper interval
depends on the condition. For details, see the
list) to operate the windshield wiper at high
speed. Turning off the windshield washer switch
causes the front-ECU to turn off the windshield
wiper relay "T" seconds later, thus operating the
wiper to the auto stop position at low speed.

• When the windshield washer switch is turned ON

during the intermittent operation of the windshield
wiper, the windshield wiper switches to
continuous operation and then resumes
intermittent operation.

• If the ignition switch is turned to ACC while the

windshield washer switch is being turned ON, the
windshield washer relay becomes ON, but the
windshield wiper does not activate linking with it.
When the windshield washer switch is turned
OFF and then ON, the windshield wiper makes
the linking operation.

NOTE:

.

•

Using a customize function, the driver can enable
or disable the windshield wiper linked with
washer function. For more information about the
customisation feature.

•

When the windshield wiper linked with washer
function is disabled by the customisation feature,
the windshield wiper does not operate in
synchronization with the windshield washer.
However, the windshield washer can be
activated. It is useful to melt down the ices of the
frozen windshield.

REAR WIPER AND WASHER
Rear wiper control [the initial condition: 8
seconds (without successive
operations)]

1. When the rear wiper switch on the column switch

is turned ON with the ignition switch at the ACC
or ON position, ETACS-ECU turns ON the rear

wiper drive signal for 3 seconds (approximately 2
operations) and performs the intermittent action
at 8-second intervals.

When the shift lever <M/T> or selector lever <A/T> is

moved to R position during the rear wiper
operation, the back-up lamp switch <M/T> or
inhibitor switch R position <A/T> turns ON one
second after that, ETACS-ECU sends the rear
wiper drive signal for 3 seconds (approximately 2
operations), and operates the intermittent action
in 8 seconds interval.

2. By the special operation of the rear wiper switch

on the column switch (successive 2-time
operations), the rear wiper operates continuously
regardless of the set intermittent time.

NOTE: The rear wiper intermittent time can be
adjusted or cancelled for continuous operation by the
customize function.

Rear wiper linked with washer function
<the initial condition: with function>

• When the rear washer switch on the column

switch is turned ON with the ignition switch ACC
or ON, ETACS-ECU turns ON the rear washer
relay. When the rear washer switch signal from
the column switch remains ON for 0.3 seconds or
more, ETACS-ECU turns ON the rear wiper relay
to operate the rear wiper continuously. When the
rear washer switch is turned OFF, the
ETACS-ECU turns OFF the rear wiper relay 3
seconds later. Then the rear wiper stops at the
auto stop position.

• Even turning ON the rear washer switch during

rear wiper operation causes the rear wiper relay
to switch the operation to continuous operation,
and then the rear wiper resumes intermittent
operation at intervals of eight seconds, 7.4
seconds after the completion of the continuous
operation.

NOTE: Using a customize function, a driver can
enable or disable the rear wiper linked with washer
function. For more information about the
customisation feature.

HEADLAMP WASHER
Headlamp washer control (Normal
control)

When the headlamp relay (LO or HI) is ON with the
ignition switch in the ACC or the ON position, turning
on the headlamp washer switch on the column
switch causes the front-ECU to turn on the headlamp
washer relay for 0.8 seconds. When the headlamp
washer relay becomes on, the headlamp washer
motor operates to spray washer fluid onto the
headlamps.

Headlamp washer control (Automatic
control)

When the headlamp relay (LO or HI) is ON with the
ignition switch in the IG ON position, turning on the
windshield washer switch causes the front-ECU to
turn on the headlamp washer relay for 0.8 seconds
once only. When the headlamp washer relay
becomes on, the headlamp washer motor operates
to spray washer fluid onto the headlamps.

NOTE: After the automatic control operated, turn the
ignition switch OFF once to operate the automatic
control again.
