− Door
Q: Is the check result normal?
YES :
Go to Step 7.
NO :
Replace the power window relay.
Step 7. Voltage measurement at the B-126 power
window relay connector.
(1) Remove the power window relay, and measure at
the junction block side.

connector terminal No.3 and body earth.
OK: System voltage
Q: Is the check result normal?
YES :
Go to Step 9.
NO :
Go to Step 8.
Step 8. Check the wiring harness between B-126
power window relay connector terminal No.3 to
fusible link (1).
NOTE:
Prior to the wiring harness inspection, check junction
block connector B-108, 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
use Troubleshooting/inspection Service
Points
− How to Cope with Intermittent
).
NO :
Repair the wiring harness.

Step 9. Resistance measurement at the B-126
power window relay connector.
(1) Remove the power window relay, and measure at
the junction block side.
(2) Resistance between B-126 power window relay
connector terminal No.2 and body earth.
OK: Continuity exists (2
Ω or less)
Q: Is the check result normal?
YES :
Go to Step 11.
NO :
Go to Step 10.
Step 10. Check the wiring harness between B-126
power window relay connector terminal No.2 to
body earth.
NOTE:
Prior to the wiring harness inspection, check junction
block connector B-131, and repair if necessary.
• Check the earth wires for open circuit.
Q: Is the check result normal?
YES :
The trouble can be an intermittent
malfunction (Refer to GROUP 00
− How to

Step 12. Check the wiring harness between B-126
power window relay connector terminal No.1 to
B-133 ETACS-ECU connector terminal No.59.
NOTE: Prior to the wiring harness inspection, check
junction block connector B-131, and repair if neces-
sary.
• Check the communication lines for open circuit.
Q: Is the check result normal?
YES :
Go to Step 13.
NO :
Repair the wiring harness.
Step 13. Resistance measurement at the D-03
power window main switch connector.
(1) Disconnect the connector, and measure at the
wiring harness side.
(2) Resistance between D-03 power window main
switch connector terminal No.2 and body earth.
OK: Continuity exists (2
Ω or less)
Q: Is the check result normal?
YES :
Go to Step 15.
NO :
Go to Step 14.
