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 works normally.
STEP 8. Measure the voltage at ETACS-ECU connector
C-304.
(1)
Disconnect ETACS-ECU connector C-304 and measure the
resistance available at the wiring harness side of the
connector.
ZC6033620000
Harness side: C-304
(2)
Measure the voltage between terminal 1 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 10.
NO:
Go to Step 9.
STEP 9. Check the wiring harness between ETACS-ECU
connector C-309 (terminal 1) and the fusible link (34).
⦆
Check the power supply line for open circuits.
Q:Is the wiring harness between ETACS-ECU connector
C-309 (terminal 1) 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 10. Check the wiring harness between ETACS-ECU
connector C-304 (terminals 5, 6) and windshield wiper
motor connector A-308 (terminals 1, 4).
⦆
Check the input and output lines for open or short ciruit.
Q:Is the wiring harness between ETACS-ECU connector
C-304 (terminals 5, 6) and windshield wiper motor
connector A-308 (terminals 1, 4) in good condition?
YES:
Go to Step 11.
NO:
Repair or replace the damaged component(s). Refer to
GROUP 00E, Cables and wire check P.00E-13.
STEP 11. Retest the system.
Check that the windshield wipers work normally.
Q:Is the check result normal?
YES:
Intermittent malfunction. Refer to GROUP 00, How to
cope with intermittent malfunction P.00-15.

DIAGNOSIS
NO:
Replace the ETACS-ECU.
INSPECTION PROCEDURE 2: The windshield wipers do not work when the wiper switch
is at the "INT", "Washer" or "Mist" position. However, the wipers work at low speed
when the switch is at the "Lo" and "Hi" position.

TECHNICAL DESCRIPTION (COMMENT)
This system may be at fail-safe mode if the LIN
communication line is defective.
If the system cannot receive any signal from the
column switch (windshield wiper and washer switch)
due to a open circuit in the LIN communication line or
other reasons, the system will enter the fail-safe mode
when the ignition switch is at the "ACC" position.
