Rear wiper linked with washer function Initial condition: with function

When the rear washer switch on the column switch is 
turned ON while the ignition switch is in ACC or ON 
position, ETACS turns the rear washer relay ON.
The rear washer relay turns ON after the rear washer 
switch has been ON for 0.3 seconds, then turns the 
rear wiper relay ON to operate the rear wiper simul-
taneously. When the rear washer switch is turned 
OFF, after 3 seconds the rear wiper is turned OFF.

If the rear washer switch is turned ON during the rear 
wiper operation, 7.4 seconds after turning OFF the 
rear wiper relay turns OFF, the intermittent action is 
resumed in 8 seconds interval.
NOTE: Using the customization function, the washer 
linked rear wiper function can be invalidated. (Refer

CIRCUIT OPERATION

• The rear wiper switch sends a signal through the 

column-ECU (incorporated in the column switch) 
to the ETACS-ECU. If the column-ECU sends a 
rear wiper switch "ON" signal to the ETACS-ECU, 
the ETACS-ECU turns on the relay (incorporated 
in the ETACS-ECU), thus causing the rear wiper 
motor to be turned on.

• The ETACS-ECU operates the rear wiper accord-

ing to the following switches:

• Ignition switch (ACC)

• Rear wiper switch

.

TECHNICAL DESCRIPTION (COMMENT)

If the rear wiper does not work normally, the input cir-
cuit system from the switches, the rear wiper motor, 
the column switch (windshield wiper and windshield 
washer switch) or the ETACS-ECU may be defective.

.

TROUBLESHOOTING HINTS

• The rear wiper motor may be defective

• The column switch (windshield wiper and washer 

switch) may be defective

• The ETACS-ECU may be defective

• The wiring harness may be damaged or the con-

nectors may have loose, corroded or damaged 
terminals, pushed back in the connector
