• Check the earth wires for open circuit.

Q: Is the check result normal?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00, How to 
use Troubleshooting/inspection Service 
Points 

− How to Cope with Intermittent 

Malfunction ).

NO : 

Repair the wiring harness.

Prior to the wiring harness inspection, check the 
junction block connector C-210 and repair if neces-
sary.

• Check the earth wires for open circuit.

Q: Is the check result normal?

YES : 

Go to Step 10.

NO : 

Repair the wiring harness.

STEP 10. Retest the system.
The windshield washer should now work normally.

Q: Is the check result normal?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00, How to 
use Troubleshooting/inspection Service

− How to Cope with Intermittent 

Malfunction ).

NO : 

Replace the ETACS-ECU and register the 
ID codes.

ON-VEHICLE SERVICE

WINDSHIELD INTERMITTENT WIPER 
INSPECTION

M1511023600071

1. Check that the intermittent wiper interval is 

changed as the windshield intermittent wiper vol-
ume is operated.

2. Turn the windshield intermittent wiper switch to 

the intermittent operation position. Use the 
M.U.T.-III to set a simulated vehicle speed with 
the wiper volume held. The intermittent wiper 
interval should be changed as the simulated vehi-
cle speed is changed.

3. If either of above is defective, carry out the trou-

bleshooting. (Refer to 

P.51-53

)

LIGHTING CONTROL SENSOR (RAIN 
SENSOR) INSPECTION

M1511028400083

Turn the ignition switch to the "ON" position when the 
windshield glass is dry, and turn the wiper switch to 
the "AUTO" position. Apply water to the upper part of 
the windshield glass where the lighting control sen-
sor is installed. Confirm that the windshield wiper 
operates at this time. If not, perform troubleshooting 
(Refer to 

P.51-93

).
