GENERAL DESCRIPTION

WINDSHIELD WIPER AND WASHER
OPERATION

.

WINDSHIELD LOW-SPEED (AND HIGH-SPEED)
WIPER OPERATION

• If the wiper switch is turned to the "LO" position

with the ignition switch at the "ACC" or "ON" posi-
tion, 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.

• If the wiper switch is turned to the "HI" 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 deter-
mines 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 oper-
ate in intermittent mode.

.

WINDSHIELD MIST WIPER OPERATION

• If the wiper switch is turned to the "MIST" 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.

• While the mist wiper switch remains turned on

when the intermittent mode is still working, the
wipers work as the mist wiper. However, the wip-
ers 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 wiper switch is turned to the "WASHER"

position with the ignition switch at "ACC" or "ON"
position, the washer ON signal is sent to the
front-ECU, causing the wiper signal to turn on
after 0.3 second. After the washer switch signal
turns off, the wiper signal turns off in three sec-
onds. If the wiper switch is turned the "WASHER"
position while the wiper is at intermittent mode,
the washer works for that period when the
washer switch remains on. Then the wipers
return to the intermittent mode.

Wiper Motor at Low-Speed and High-Speed Operation
Connect the battery to the wiper motor as shown in the illustra-
tion, and then check the operation of the wiper motor at low
speed and at high speed.

.

Wiper Motor at Stop Position Operation
1. Connect the battery to the wiper motor as shown in

illustration (A), and then run the wiper motor at low speed.
Then, while the motor is operating, disconnect the battery to
make the wiper motor stop.

2. Connect the terminals and the battery as shown in

illustration (B), and then check whether the wiper motor
automatically stops in the correct stop position after it has
been running at low speed.
