STEP1. Check windshield wiper motor connector A-08 for
loose, corroded or damaged terminals, or terminals pushed
back in the connector.

Q:Is windshield wiper motor connector A-08 in good

condition?

YES:

Go to Step 2.

NO:

Repair or replace the damaged component(s). Refer to

(1)

Disconnect windshield wiper motor connector A-08 and
measure the voltage available at the wiring harness side of
the connector.

(2)

Turn the ignition switch to the "ACC" position.

ZC6033620001

Harness side: A-08

(3)

Measure the voltage between terminal 2 and ground.

｠

The voltage should measure approximately 12 volts
(battery positive voltage).

Q:Is the measured voltage approximately 12 volts (battery

positive voltage)?

YES:

Go to Step 5.

NO:

Go to Step 4.

STEP 4. Check the wiring harness between windshield
wiper motor connector A-08 (terminal 2) and the fusible link
(34).

｠

Check the power supply line for open circuits.

Q:Is the wiring harness between windshield wiper motor

connector A-08 (terminal 2) and the fusible link (34) in

good condition?

YES:

Intermittent malfunction. Refer to GROUP 00, How to

cope with intermittent malfunction P.00-15.

NO:

Repair or replace the damaged component(s). Refer to

GROUP 00E, Cables and wire check P.00E-13.

STEP 5. Check ETACS-ECU connector C-304 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.

Q:Is ETACS-ECU connector C-304 in good condition?

YES:

Go to Step 6.

NO:

Repair or replace the damaged component(s). Refer to

GROUP 00E, Harness Connector Inspection P.00E-2.

STEP 6. Check the wiring harness between ETACS-ECU
connector C-304 (terminals 8, 12) and windshield wiper
motor connector A-08 (terminals 2, 3).

｠

Check the output lines for open or short circuits.

Q:Is the wiring harness between ETACS-ECU connector

C-304 (terminals 8, 12) and windshield wiper motor

connector A-08 (terminals 2, 3) in good condition?

YES:

Go to Step 7.

NO:

Repair or replace the damaged component(s). Refer to

GROUP 00E, Cables and wire check P.00E-13.

STEP 7. Retest the system.
Check that the windshield wipers stops at the specified park
position.
