INSPECTION

M1511019100567

FRONT WIPER MOTOR CHECK

Check the wiper motor after disconnecting the wiring harness 
connector, and with the wiper motor remaining installed to the 
body.

.

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. Run the wiper motor at low-speed, disconnect the battery, 

and stop the motor.

2. Reconnect the battery as shown in the illustration, and 

confirm that the motor starts turning at low-speed, and then 
stops at the automatic stop position.

FRONT WASHER MOTOR CHECK

1. With the washer motor installed to the washer tank, fill the 

washer tank with water.

2. Check that water is sprayed out strongly when battery 

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

Measure the resistance value at terminal numbers 27 and

approximately 0 

Ω ("FAST" position) to approximately 1 kΩ 

("SLOW" position). 

REAR WIPER AND WASHER

GENERAL INFORMATION

M1511000100138

OPERATION
Rear Wiper Operation

• If the rear wiper and washer switch is turned to 

the "INT" position with the ignition switch at 
"ACC" or "ON" position, the ETACS-ECU causes 
the rear wiper to operate continuously two times, 
then intermittently at eight-second intervals.

• If the selector lever is moved to the "R" position 

when the rear wiper and washer switch is turned 
the "INT" position and the ignition switch at 
"ACC" or "ON" position, park/neutral position 
switch "R" turns ON. One second later, the 
ETACS-ECU causes the rear wiper to operate 
two times continuously to ensure good rearward 
visibility. The ETACS-ECU then causes the rear 
wiper to again operate intermittently at eight-sec-
ond intervals.

Rear Washer Operation

• If the rear wiper and washer switch is turned the 

"WASHER" position with the ignition switch at 
"ACC" or "ON" position, the rear washer ON sig-
nal is sent to the ETACS-ECU, causing the rear 
wiper signal to turn on after 0.9 seconds. After the 
rear washer switch signal turns off, the rear wiper 
signal turns off in three seconds.

• If the rear wiper and washer switch is turned to 

the "WASHER" position while the rear wiper is at 
intermittent mode, the rear washer works for that 
period when the washer switch remains on. Then 
the rear wipers return to the intermittent mode. 

EXTERIOR DIAGNOSIS

M1511000700118

The rear wiper and washer are controlled by 
ETACS-ECU. For troubleshooting, refer to GROUP 
54B, SWS Diagnosis
