STEP 8. Check the wiring harness between C-302
column switch connector terminal No.9 and
ignition switch (IG1).
NOTE:
Prior to the wiring harness inspection, check junction
block connectors C-207, C-209 and joint connector
C-132, and repair if necessary.
• Check the power supply line for open circuit and
short circuit.

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.
STEP 9. Connector check: C-219 ETACS-ECU
connector
Q: Is the check result normal?
YES :
Go to Step 10.
NO :
Repair the defective connector.
STEP 10. Check the wiring harness between C-
302 column switch connector terminal No.3 and
C-219 ETACS-ECU connector terminal No.54.
• Check the communication lines for open circuit.
Q: Is the check result normal?
YES :
Go to Step 11.
NO :
Repair the wiring harness.

(2) Check that the signals from the column switch
are received.
Q: Is the check result normal?
YES :
The procedure is complete.
NO :
Replace the ETACS-ECU and register the
ID codes (Refer to
Inspection Procedure C-2: The ignition switch (ACC) signal is not received.
CAUTION
Whenever the ECU is replaced, ensure that the input signal circuit is normal.
COMMENTS ON TROUBLE SYMPTOM
Input signal from the ignition switch (ACC) is used to
operate the windshield wiper and washer. If the sig-
nal is abnormal, windshield wiper and washer will not
work normally.
PROBABLE CAUSES
• Malfunction of the ETACS-ECU
• Damaged harness wires and connectors

DIAGNOSIS PROCEDURE
STEP 1. Connector check: C-219 ETACS-ECU
connector
Q: Is the check result normal?
YES :
Go to Step 2.
NO :
Repair the defective connector.
STEP 2. Voltage measurement at the C-219
ETACS-ECU connector.
(1) Disconnect the connector, and measure at the
wiring harness side.
(2) Turn the ignition switch to the "ACC" position.
(3) Voltage between C-219 ETACS-ECU connector
terminal No.74 and body earth
OK: System voltage
Q: Is the check result normal?
YES :
Go to Step 4.
NO :
Go to Step 3.
