Step 6. Check the power window relay.
Refer to GROUP 42 

− Door 

P.42-36

.

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.

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 

Malfunction 

P.00-13

).

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 

use Troubleshooting/inspection Service 
Points 

− How to Cope with Intermittent 

Malfunction

).

NO : 

Repair the wiring harness.

Step 11. Connector check: B-133 ETACS-ECU 
connector

Q: Is the check result normal?

YES : 

Go to Step 12.

NO : 

Repair the defective connector.

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.
