TROUBLE SYMPTOM

Inspection 
procedure 
No.

Reference 
page

The windshield wipers do not work at all.

1

P.51-24

The windshield wipers do not work when the wiper switch is at the "INT", 
"Washer" or "Mist" position. However, the wipers work at low speed when the 
switch is at the "Lo" and "Hi" position.

2

P.51-26

The windshield wipers do not stop at the specified park position.

3

P.51-27

The windshield wipers do not work normally.

4

P.51-27

The windshield intermittent wiper interval cannot be adjusted by operating the 
windshield intermittent wiper volume control.

5

P.51-29

The intermittent wiper interval is not changed according to the vehicle speed.

6

P.51-30

The rain sensitive AUTO wiper function does not work at all <Vehicles with 
lighting control sensor>.

7

P.51-30

The rain sensitive AUTO wiper function works even though there is no rainfall 
<Vehicles with lighting control sensor>.

8

P.51-32

Sometimes the rain sensitive AUTO wiper function works even though there is 
no rainfall <Vehicles with lighting control sensor>.

9

P.51-33

The windshield washer does not work.

10

P.51-33

The comfort washing function does not work normally

11

P.51-35

Delayed finishing wipe function does not work normally.

12

P.51-35

NOTE: If the ETACS-ECU failed, the windshield 
wiper will operate only at low speed as a fail-safe 
measure.

Inspection Procedure 1: The windshield wipers do not work at all.

CAUTION

Whenever ECU is replaced, ensure that the input and output signal circuits are normal.

COMMENTS ON TROUBLE SYMPTOM

The windshield wiper motor, the column switch (col-
umn-ECU) or ETACS-ECU may be defective. Check 

the wiper backup circuit (between the column switch 
WB/U and the ETACS-ECU WB/U), and repair if nec-
essary.

PROBABLE CAUSES

• Defective windshield wiper motor

• Malfunction of ETACS-ECU

• Defective column switch (column-ECU)

• Malfunctions of the wiring harness and connec-

tors

DIAGNOSTIC PROCEDURE

STEP 1. M.U.T.-III diagnosis code
Check if an ETACS-related diagnosis code is set.

Q: Is the diagnosis code set?

YES : 

Diagnose the ETACS-ECU (Refer to 

GROUP 54A 

− ETACS, Trouble Symptom 

Chart ).

NO : 

Go to Step 2.

STEP 2. M.U.T.-III data list
Check the input signal related to the windshield wiper 
operation.

• Turn the ignition switch to the ACC position.

items> : 

Go to Step 3.

GROUP 54A 

− ETACS, Diagnosis - 

Inspection Procedure 11 "Column switch 
signal is not received." .

NO <Normal condition is not displayed for item No. 
288> : 

GROUP 54A 

− ETACS, Diagnosis - 

Inspection Procedure 1 "The ignition switch 
(ACC) signal is not received" .

STEP 3. Check the windshield wiper motor.
Check that the windshield wiper motor works nor-
mally. Refer to 

P.51-42

.

Q: Is the check result normal?

YES : 

Go to Step 4.

NO : 

Replace the windshield wiper motor.

STEP 4. Measure the resistance at windshield 
wiper motor connector.
(1) Disconnect the connector, and measure the 

resistance at the wiring harness.

(2) Measure the resistance between the windshield 

wiper motor connector earth terminal and body 
earth.

OK: Continuity exists (2 

Ω or less)

Q: Is the check result normal?

YES : 

Go to Step 6.

NO : 

Go to Step 5.

STEP 5. Check the wiring harness between 
windshield wiper motor connector and body 
earth.

Q: Is the check result normal?

YES : 

Intermittent malfunction (Refer to GROUP 

00 

− How to Use 

Troubleshooting/Inspection Service Points - 
How to Cope with Intermittent Malfunction ).

NO : 

Repair the connector(s) or wiring harness.

STEP 6. Measure the voltage at ETACS-ECU 
connector.
(1) Disconnect the connector, and measure the 

voltage at the wiring harness side.

(2) Measure the voltage between the 

ETACS-ECU(+B1 terminal) and the body earth.

OK: System voltage

Q: Is the check result normal?

YES : 

Go to Step 8.

NO : 

Go to Step 7.

STEP 7. Check of open in power supply line 
between fusible link and ETACS(+B terminal).

Q: Is the check result normal?

YES : 

Intermittent malfunction. Refer to GROUP 

00 

− How to Use 

Troubleshooting/Inspection Service Points, 
− How to Cope with Intermittent 
Malfunctions .)

NO : 

Repair the connector(s) or wiring harness.

STEP 8.Check of open, short circuit in W.LO, HI 
line between windshield wiper motor connector 
and ETACS-ECU connector

YES : 

Go to Step 9.

NO : 

Repair the connector(s) or wiring harness.

STEP 9. Check the trouble symptom.
Check that the windshield wipers work normally.

Q: Is the check result normal?

YES : 

Intermittent malfunction. Refer to GROUP 

00 

− How to Use 

Troubleshooting/Inspection Service Points, 
− How to Cope with Intermittent 
Malfunctions .)

NO : 

Replace the ETACS-ECU.

INSPECTION PROCEDURE 2: The windshield wipers do not work when the wiper switch is at the 
"INT", "Washer" or "Mist" position. However, the wipers work at low speed when the switch is at the 
"Lo" and "Hi" position.

CAUTION

Whenever the ECU is replaced, ensure that the 
communication circuit is normal.

COMMENTS ON TROUBLE SYMPTOM

It is assumed that the windshield wipers are in the 
fail-safe mode due to the LIN bus lines failure.

PROBABLE CAUSES

• Faulty LIN bus line

• Malfunction of ETACS-ECU

• Defective column switch (column-ECU)

• Malfunctions of the wiring harness and connec-

tors

DIAGNOSTIC PROCEDURE

STEP 1. M.U.T.-III diagnosis code
Check if an ETACS-related diagnosis code is set.

Q: Is the diagnosis code set?

YES : 

Troubleshoot the ETACS. Refer to GROUP 

54A 

− ETACS .

NO : 

Go to Step 2.

STEP 2. M.U.T.-III data list
Check the input signal related to the windshield wiper 
operation.

• Turn the ignition switch to the ACC position.
