Step 12. Check the wiring harness between C-224 
power window relay connector terminal No.4 and 
E-05 power window main switch connector 
terminal No.6.

NOTE: Prior to the wiring harness inspection, check 
intermediate connectors C-17 <LH drive vehicles>, 
C-110 <RH drive vehicles> and junction block con-
nector C-211, 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 

P.00-5

).

NO : 

Repair the harness wire.

Step 13. Resistance measurement at E-05 power 
window main switch connector

(1) Disconnect the connector, and measure at the 

harness side.

(2) Resistance between terminal 2 and body earth

OK: 2

Ω or less

Q: Is the check result normal?

YES : 

Go to Step 15.

NO : 

Go to Step 14.

Step 14. Check the wiring harness between E-05 
power window main switch connector terminal 
No.2 and body earth.

NOTE: Prior to the wiring harness inspection, check 
intermediate connector C-17 <LH drive vehicles> or 
C-110 <RH drive vehicles>, and repair if necessary.

• Check the earth wires for open circuit.

The trouble can be an intermittent 

malfunction (Refer to GROUP 00, How to 
Cope with Intermittent Malfunction 

P.00-5

).

NO : 

Repair the wiring harness.

Step 15. Retest the system.
After the power window main switch is replaced, 
check that all the power windows work.
(1) Replace the power window main switch.

(2) Check that the all the power windows work.

Q: Is the check result normal?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00 

− How to 

Cope with Intermittent Malfunction 

P.00-5

).

NO : 

Replace the ETACS-ECU.

INSPECTION PROCEDURE D-2: Driver's power window does not work by means of the power window 
main switch. <LH drive vehicles>

COMMENTS ON TROUBLE SYMPTOM

If the driver's power window does not work by means 
of the power window main switch, the power window 
main switch or the driver's door power window regu-
lator motor may be defective.

POSSIBLE CAUSES

• Malfunction of the power window main switch

DIAGNOSIS PROCEDURE

STEP 1. Check the power window main switch.
Check that all of the front passenger's and rear door 
power windows can operate by means of the power 
window main switch.

Q: Is the check result normal?

YES : 

Go to Step 2.

NO : 

Refer to Inspection Procedure D-1 "Power 
windows do not work at all 

P.54B-72

."

STEP 2. Connector check: E-05 power window 
main switch connector and E-02 front power 
window regulator motor (LH) connector

Q: Are the check result normal?

YES : 

Go to Step 3.

NO : 

Repair the connector.

STEP 3. Check the wiring harness from E-02 front 
power window regulator motor (LH) connector 
terminal Nos.1 and 4 to E-05 power window main 
switch connector terminal Nos.7 and 1.

• Check the input and output lines for open or short 

circuit.

Q: Is the check result normal?

YES : 

Go to Step 4.

NO : 

Repair the wiring harness.

STEP 4. Retest the system.
After the power window main switch is replaced, 
check that the driver's door power window can be 
operated by the power window main switch.
(1) Replace the power window main switch.
(2) Check that the driver's power window works by 

means of the power window main switch.

Q: Is the check result normal?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00
