GENERAL DESCRIPTION WINDSHIELD WIPER AND WASHER OPERATION WINDSHIELD LOW-SPEED (AND HIGH-SPEED) WIPER OPERATION
If 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 control relay off (low-speed),
causing the wipers to operate at low-speed. If 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 control
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 relay 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
NOTE: The windshield wiper speed is adjustable with the built-
in wiper speed control relay. High-speed operations
take place when the wiper speed control relay is set to
"ON" and low-speed operations take place when the
wiper speed control relay is set to "OFF".

If the windshield mist wiper switch is turned to the ON position, with the
ignition switch at the "ACC" or "ON" position, the mist wiper high-speed
operation signal is sent to the front-ECU. This signal turns on the wiper speed
control relay, causing the wipers to work at high-speed while the mist switch is
on. While 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 switch is changed
back to "INT" position. To prevent the windshield mist wiper from operating when the windshield
wiper switch is turned OFF, the windshield mist wiper does not work for 0.5
second after the windshield intermittent wiper switch, the windshield low-
speed wiper switch and the windshield high-speed wiper switch are turned
OFF.
WINDSHIELD WASHER OPERATION
If the windshield washer 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. After 0.3 second, the windshield wiper signal turns on. After
the windshield washer switch signal turns off, the windshield wiper signal
turns off in three seconds. If the windshield washer switch is turned on while the windshield wiper is at
intermittent mode, and the windshield washer switch is turned OFF within 0.2
second, the wiper works only once to perform mist operation. When the
windshield washer switch is turned on for more than 0.2 second, the wiper
performs the same movement as normal condition from the time when 0.2
second has elapsed, and then returns to intermittent operation.
WINDSHIELD WIPER AND WASHER DIAGNOSIS The windshield wiper and washer are controlled by the Simplified Wiring System
(SWS). For troubleshooting, refer to SWS DIAGNOSIS
.
NOTE: Even when the ETACS-ECU has failed, the windshield wiper
can work at low speed in fail-safe mode. (Normally, the

ON-VEHICLE SERVICE WINDSHIELD INTERMITTENT WIPER VOLUME CHECK 1. If the windshield intermittent wiper volume is operated, the wiper interval
should change.
2. Holding the windshield intermittent wiper volume, input the simulated vehicle
speed with scan tool MB991958 and check that the wiper interval changes as
the vehicle speed changes.
3. If not, carry out the troubleshooting (Refer to SWS DIAGNOSIS
).
WINDSHIELD WASHER FLUID EJECTION CHECK The windshield washer nozzle aiming can not be adjusted. If the washer nozzles do
not spray washer fluid within the swept area, check the nozzles as follows.
1. Check that the windshield washer nozzles are fitted on the hood correctly, and
reinstall them if necessary. windshield wiper operates when the ignition switch is at the
"ACC" or "ON" position. But, if it enters the fail-safe mode,
the wiper can operate only when the ignition switch is at the
"ON" position).
