Inspection Procedure 6: The intermittent wiper interval is not changed according to the vehicle 
speed.

CAUTION

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

OPERATION

The ETACS-ECU calculates the intermittent wiper 
interval according to the vehicle speed signal which 
is sent by the ABS-ECU <Vehicles without ASC> or 
ASC-ECU <Vehicles with ASC>.

COMMENTS ON TROUBLE SYMPTOM

If the intermittent wiper interval does not depend on 
the vehicle speed, the input circuit of the vehicle 
speed signal (combination meter) and the 
ETACS-ECU may be defective. Alternatively, the 
vehicle speed-dependent wiper may be set to "disa-
bled" by using the customise function.

PROBABLE CAUSES

• Defective combination meter

• Malfunction of ETACS-ECU

• Damaged wiring harness and connectors

DIAGNOSTIC PROCEDURE

STEP 1. Check the operation of windshield 
intermittent wiper volume control.
Check that the windshield intermittent wiper interval 
can be adjusted by operating the windshield intermit-
tent wiper volume control.

Q: Is the check result normal?

YES : 

Go to Step 2.

NO : 

Refer to Inspection Procedure 5 "The 
windshield intermittent wiper interval cannot 
be adjusted by operating the windshield 
intermittent wiper volume control" 

P.51-29

.

STEP 2. Check the ETACS customise function.
Use the ETACS customise function to confirm that 
"FRONT WIPER OPERATION" is set to "VEHICLE 
SPEED DEPENDENT".

Q: Is the check result normal?

YES : 

Go to Step 3.

NO : 

Use the ETACS customise function to set 
"FRONT WIPER OPERATION" to 
"VEHICLE SPEED DEPENDENT" (Refer to 

P.51-37

).

STEP 3.Check the speedometer.
(1) Connect the M.U.T.-III to the diagnosis connector.
(2) Use the M.U.T.-III to enter simulated vehicle 

speed.

• Item No.1: Speedometer (Refer to .)

OK: The speedometer shows that simu-
lated vehicle speed.

Q: Is the check result normal?

YES : 

Go to Step 4.

No : 

Perform the troubleshooting to the 
speedometer (Refer to GROUP 54A 

− 

Combination Meter, Inspection Procedure 5 
"Speedometer does not work." Refer to .)

STEP 4. Retest the system.
Check that the intermittent wiper interval depends on 
the vehicle speed.

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 : 

Replace the ETACS-ECU.

Inspection Procedure 7: The rain sensitive AUTO wiper function does not work at all <Vehicles with 
lighting control sensor>. 

CAUTION

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

OPERATION

The raindrops sensitive wiper function automatically 
adjusts the wiping speed of windscreen wiper by 

detecting the rainfall through lighting control sensor 
when the ignition switch is in the ON position and the 
column switch is in the AUTO position.
