COMMENTS ON TROUBLE SYMPTOM
Input signal from the power window main switch is
used in order to check the power window main
switch and confirm how the system is communicating
with the ETACS-ECU. If the communication line is
defective, the power windows will not work normally.
POSSIBLE CAUSES
• Malfunction of the power window main switch
• Damaged harness wires and connectors

DIAGNOSTIC PROCEDURE
Step 1. Check the operation by using the power
window main switch.
Check if each window can be operated by means of
the power window main switch.
Q: Can each power window be operated by means of
the power window main switch?
YES :
Go to Step 2.
NO :
Go to Step 5.
Step 2. Connector check: C-221 ETACS-ECU
connector and F-05 power window main switch
connector
Q: Is the check result normal?
YES :
Go to Step 3.
NO :
Repair the defective connector.

Step 3. Check the wiring harness between C-221
ETACS-ECU connector terminal No.59 and F-05
power window main switch connector terminal
No.4.
NOTE:
Prior to the wiring harness inspection, check
intermediate connectors C-27 <LH drive vehicles>,
C-14 <RH drive vehicles> and joint connector C-01,
and repair if necessary.
• Check the communication lines for open circuit.
Q: Is the check result normal?
YES :
Go to Step 4.
NO :
Repair the wiring harness.

Step 4. Replace the power window main switch,
and then retest the system.
Replace the power window main switch, and check
that the power window main switch signal is
received.
(1) Replace the power window main switch.
(2) Check that the power window main switch signal
is received.
Q: Is the check result normal?
YES :
The procedure is complete.
NO :
Replace the ETACS-ECU.
Step 5. Voltage measurement at the F-05 power
window main switch connector.
(1) Remove the power window main switch, and
measure at the wiring harness side.
(2) Ignition switch: ON position
(3) Voltage between F-05 power window main switch
connector terminal No.6 and body earth
OK: System voltage
Q: Is the check result normal?
YES :
Go to Step 8.
NO :
Go to Step 6.
Step 6. Connector check: C-217 power window
relay connector
Q: Is the check result normal?
YES :
Go to Step 7.
NO :
Repair the defective connector.
