54B-177

NOTE: 

Prior to the wiring harness inspection, check the 
intermediate connector A-14, and repair if necessary.

•

Check the power supply line to front-ECU for 
open circuit.

Q: Is the check result normal?

YES : 

Go to Step 14.

NO : 

Replace the front-ECU.

Step 14. Retest the system.

Check that the windshield wipers work normally by 
moving the switch to each position.

Q: Is the check result normal?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00 

−

 How to 

Cope with Intermittent Malfunction 

P.00-6

).

NO : 

Replace the windshield wiper motor.

SYMPTOM PROCEDURES

SMART WIRING SYSTEM (SWS) NOT USING SWS MONITOR

54B-178

INSPECTION PROCEDURE F-5: The intermittent wiper interval can not be adjusted by operating the 
windshield intermittent wiper volume control.

CAUTION

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

COMMENTS ON TROUBLE SYMPTOM
The column switch or the front-ECU may be 
defective.

POSSIBLE CAUSES

•

Malfunction of the column switch

•

Malfunction of the front-ECU

•

Damaged harness wires and connectors

DIAGNOSIS PROCEDURE

Step 1. Pulse check

Check the input signals below which are related to 
the windshield intermittent wiper function.

OK: The MUT-II/III sounds or the voltmeter 
needle fluctuates.

Q: Is the check result normal?

All the signals are received normally. : 

Go to Step 

2.

The ignition switch (IG1) signal is not received. : 

Refer to inspection procedure N-1 "The 
ignition switch (ACC) signal is not received 

P.54B-298

."

The windshield wiper volume signal is not 
received. : 

Refer to inspection procedure N-7 "The 

windshield wiper volume signal is not 
received 

P.54B-321

."

Step 2. Retest the system.

Check that the windshield intermittent wiper interval 
can be adjusted by operating the windshield 
intermittent wiper volume control.

OK: The intermittent wiper interval is 
changed as the intermittent wiper volume is 
rotated.

Q: Is the check result normal?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00 

−

 How to 

Cope with Intermittent Malfunction 

P.00-6

).

NO : 

Replace the front-ECU

INSPECTION PROCEDURE F-6: The intermittent wiper interval is not changed according to the 
vehicle speed.

CAUTION

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

COMMENTS ON TROUBLE SYMPTOM
The ETACS-ECU calculates the intermittent wiper 
interval according to the vehicle speed signal which 
is sent by the engine-ECU.
If the intermittent wiper interval does not depend on 
the vehicle speed, the input circuit of the vehicle 
speed signal and the ETACS-ECU may be defective.

POSSIBLE CAUSES

•

Malfunction of the vehicle speed signal 
(engine-ECU)

•

Malfunction of the ETACS-ECU

•

Damaged harness wires and connectors

DIAGNOSIS PROCEDURE

Step 1. Retest the system.

Check that the windshield intermittent wiper interval 
can be adjusted by operating the windshield 
intermittent wiper volume control.

Q: Is the check result normal?

YES : 

Go to Step 2.

NO : 

Refer to Inspection Procedure F-5 "The 
intermittent wiper interval can not be 
adjusted by operating the windshield 
intermittent wiper volume control 

P.54B-178

."

Step 2. Pulse check

Check the input signals below which are related to 
the vehicle speed-dependent intermittent wiper.

OK: The MUT-II/III sounds or the voltmeter 
needle fluctuates.

Q: Is the check result normal?

All the signals are received normally. : 

Go to Step 

3.

The ignition switch (IG1) signal is not received. : 

Refer to inspection procedure N-1 "The 
ignition switch (ACC) signal is not received 

P.54B-298

."

The vehicle speed signal (engine-ECU) is not 
received. : 

Refer to inspection procedure N-13 

"The vehicle speed signal is not received

Step 3. Check the SWS monitor customized 
function.

Use the SWS monitor customize function to confirm 
that "SPEED SEN WIP" is set to "W.FUNCTION".

CAUTION

The SWS monitor must be used in order to 
confirm and change that setting. Use the SWS 
monitor to confirm and/or change the 
customized function.

Q: Is the check result normal?

YES : 

Go to Step 4.

NO : 

Use the SWS monitor customize function to 
set the "SPEED SEN WIP" to 
"W.FUNCTION" (Refer to GROUP 54B

).

Step 4. Retest the system.

Check that the intermittent wiper interval depends on 
the vehicle speed.

Q: Is the check result normal?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00
