COMMENTS ON TROUBLE SYMPTOM
If the power windows do not work at all, the power
window relay, the power window main switch or the
ETACS-ECU may be defective.
POSSIBLE CAUSES
• Malfunction of the power window relay
• Malfunction of the power window main switch
• Malfunction of the ETACS-ECU
• Damaged harness wires and connectors
DIAGNOSIS PROCEDURE
Step 1. Pulse check
Check the input signal from the ignition switch.
OK: The MUT-III sounds or the voltmeter
needle fluctuates.
Q: Is the check result normal?
YES :
Go to Step 2.
NO :
Refer to inspection procedure A-2 "When
the ignition switch is at the LOCK (OFF)
position, the functions do not work normally.
Check the battery power supply circuit to
the ETACS-ECU
Step 2. Connector check: F-05 power window
main switch connector
Q: Is the check result normal?
YES :
Go to Step 3.
NO :
Repair the connector.
Step 3. Voltage measurement at the F-05 power
window main switch connector.
(1) Disconnect the connector, and measure at the
wiring harness side.

Step 7. Check the wiring harness between C-217
power window relay connector terminal No.5 and
fusible link (5).
NOTE:
Prior to the wiring harness inspection, check
intermediate connectors C-125 and junction block
connector C-202, and repair if necessary.
• Check the power supply line for open circuit.
Q: Is the check result normal?
YES :
The trouble can be an intermittent
malfunction (Refer to GROUP 00, How to
Cope with Intermittent Malfunction
NO :
Repair the wiring harness.
