Step 6. Check the wiring harness between E-04 
rear wiper motor connector terminal No.1 to body 
earth.

• Check the earth line for open or short 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

).

NO : 

Repair the wiring harness.

Step 7. Connector check: B-134 ETACS-ECU 
connector.

Q: Is the check result normal?

YES : 

Go to Step 8.

NO : 

Repair the connector.

Step 8. Check the wiring harness between B-134 
ETACS-ECU connector terminal No.13 to E-04 
rear wiper motor connector terminal No.2.

NOTE: 

Prior to the wiring harness inspection, check interme-
diate connector C-12 and junction block connectors 
B-128, and repair if necessary.

• Check the output line.

INSPECTION PROCEDURE G-2: The rear wiper does not stop at the specified park position.

CAUTION

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

COMMENTS ON TROUBLE SYMPTOM

If the rear wiper does not stop normally within the 
predetermined range, the rear wiper motor or the 
ETACS-ECU may be defective.

POSSIBLE CAUSES

• Malfunction of the rear wiper motor
