STEP 5. Check the windshield wiper motor.
(1) Disconnect windshield wiper motor connector A-08.
(2) Connect a battery to the windshield wiper motor as shown.

Then check if the windshield wiper motor operates normally
at high and low speeds.

Q: Does the windshield wiper motor operate normally?

YES : Go to Step 6.
NO : Replace the windshield wiper motor. Verify that the

windshield wiper operates normally when the
windshield wiper switch is moved to each position.

STEP 6. Measure the voltage at windshield wiper motor
connector A-08
(1) Disconnect the connector, and measure the voltage at the

wiring harness side.

(2) Ignition switch: ACC
(3) windshield wiper switch: LO
(4) Measure the voltage between A-08 windshield wiper motor

connector terminal No. 3 and body ground.

OK: Battery positive voltage

Q: Is the measured voltage approximately 12 volts (battery

positive voltage)?
YES : Intermittent malfunction (Refer to GROUP 00

− How

to Use Troubleshooting/Inspection Service Points -
How to Cope with Intermittent Malfunction

P.00-15

).

NO : Go to Step 7.

STEP 7. 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 8.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection

P.00E-2

. Verify that the windshield wiper operates

normally when the windshield wiper switch is moved
to each position.

STEP 8. Check the wiring harness between windshield
wiper motor connector A-08 (terminals 1) and ETACS-ECU
connector C-304 (terminals 5).

• Check the output lines for open or short circuit.

Q: Is the wiring harness between windshield wiper motor

connector A-08 (terminals 1) and ETACS-ECU connector
C-304 (terminals 5) in good condition?
YES : Go to Step 9.
NO : The wiring harness may be damaged or the

connector(s) may have loose, corroded or damaged
terminals, or terminals pushed back in the connector.
Repair the wiring harness as necessary. Verify that
the windshield wiper operates normally when the
windshield wiper switch is moved to each position.

STEP 9. Retest the system.
Check that the windshield wipers work normally by moving the
switch to each position.
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.

STEP 10. Check the A-08 windshield wiper motor
connector
Q: Is the check result normal?

YES : Go to Step 11.
NO : Repair the connector concerned.

STEP 11. Check the windshield wiper motor.
(1) Disconnect windshield wiper motor connector A-08.
(2) Connect a battery to the windshield wiper motor as shown.

Then check if the windshield wiper motor operates normally
at high and low speeds.

Q: Does the windshield wiper motor operate normally?

YES : Go to Step 12.
NO : Replace the windshield wiper motor. Verify that the

windshield wiper operates normally when the
windshield wiper switch is moved to each position.

STEP 12. Measure the voltage at the A-08 windshield wiper
motor connector.
(1) Disconnect the connector, and measure the voltage at the

wiring harness side.

(2) Ignition switch: ACC
(3) Windshield wiper switch: HI,MIST
(4) Measure the voltage between A-08 windshield wiper motor

connector terminal No.4 and body ground.

OK: Battery positive voltage

Q: Is the check result normal?

YES : Intermittent malfunction (Refer to GROUP 00

NO : Go to Step 13.

STEP 13. 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 14.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection

).

NO : Replace the ETACS-ECU.

INSPECTION PROCEDURE 5: The windshield intermittent wiper interval cannot be adjusted by
operating the windshield intermittent wiper volume control switch.

.

TECHNICAL DESCRIPTION (COMMENT)

If the windshield intermittent wiper interval is not
changed by operating the windshield intermittent
wiper interval adjusting knob or according to the
vehicle speed, the column switch or the ETACS-ECU
may be defective.

.

TROUBLESHOOTING HINTS
