WINDSHIELD WIPER AND WASHER

GENERAL DESCRIPTION

M1511000100558

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 sig-
nal 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 WIPER AND WASHER

TSB Revision

EXTERIOR

51-12

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".

.

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

• 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 oper-
ation 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 work-
ing, the wipers work as the mist wiper. However, 
the wipers return to the intermittent mode again 
when the switch is changed back to "INT" posi-
tion.

• To prevent the windshield mist wiper from operat-

ing 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 wind-
shield 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 sec-
ond, 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

M1511000700389

The windshield wiper and washer are controlled by 
the Simplified Wiring System (SWS). For trouble-
shooting, refer to GROUP 54B, SWS Diagnosis 

P.54B-9

.

NOTE: Even when the ETACS-ECU has failed, the 
windshield wiper can work at low speed as fail-safe 
mode. (Normally, the windshield wiper operates 
when the ignition switch is at the "ACC" position. But, 
if it enters the fail-safe mode, the wiper can operate 
only when the ignition switch is at the "ON" position.)
