WINDSHIELD WASHER MOTOR CHECK

1. The windshield washer tank assembly should be installed 

and the windshield washer tank should be filled with water 
when checking the washer motor.

2. Check that water is sprayed out strongly when battery 

positive voltage is applied to terminal (1) and terminal (2) is 
grounded.

WINDSHIELD  WASHER FLUID LEVEL SWITCH 
CHECK

1. Connect a circuit tester to the connector of the level sensor 

as shown.

2. Check that when the float is moved down, the circuit is 

closed and that when the float is moved up, the circuit is 
opened.

REAR WIPER AND WASHER

GENERAL DESCRIPTION

REAR WIPER AND WASHER OPERATION

.

REAR WIPER OPERATION

• If the rear wiper switch of the column switch 

assembly is turned ON with the ignition switch in 
the ACC or ON position, the ETACS-ECU turns 
ON the rear wiper drive signal for three seconds 
(approx. two operations). 7.4 seconds later, the 
wiper begins the intermittent operation with eight 
seconds' cycle. If the selector lever is moved to 
the R position when the rear wiper switch of the 
column switch assembly is turned ON and the 
ignition switch is in any position other than OFF, 
transmission range switch (reverse) turns ON. 
One second later, the ETACS-ECU turns ON the 
rear wiper drive signal for three seconds (approx. 
two operations) to clear the rear field of view. 7.4 
seconds later, the wiper returns to the intermittent 
operation of eight seconds' cycle.

.

REAR WASHER OPERATION

• If the washer switch at the steering column is 

placed in the ON position when the ignition switch 
is in the ACC or ON position, the rear washer 
switch signal to the ETACS-ECU is set to high. 
Then the wiper drive signal turns ON 0.3 second 
and turns OFF three seconds after the rear 
washer switch signal has become low. If the rear 
wiper is in intermittent operation when the rear 
washer switch is turned ON, the rear wiper again 
continues the intermittent operation with eight 
seconds' cycle from 7.4 seconds after the rear 
wiper drive signal is turned OFF.

REAR WIPER AND WASHER DIAGNOSIS

M1511000700420

The rear wiper and washer are controlled by the Sim-
plified Wiring System (SWS). For troubleshooting, 
refer to GROUP 54B, SWS Diagnosis
