Step 2. Check the power window sub switch.
Check that each power window works by means of 
the respective power window sub switch when the 
power window lock switch is turned off.

Q: Is the check result normal?

YES : 

Go to Step 3.

NO : 

Refer to Inspection Procedure D-3 
"Relevant power window(s) do not work by

."

Step 3. Retest the system.
Check that the rear left 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 

− How to 

use Troubleshooting/inspection Service 
Points 

− How to Cope with Intermittent 

Malfunction 

P.00-13

).

NO : 

Replace the power window main switch.

Inspection Procedure D-5: The power window timer function does not work normally.

CAUTION

Whenever the ECU is replaced, ensure that the 
input and output signal circuits are normal.

COMMENTS ON TROUBLE SYMPTOM

If the power window timer function does not work 
normally, these input signal circuit(s), the 
ETACS-ECU may be defective.

POSSIBLE CAUSES

• Malfunction of the driver's door switch

• Malfunction of the passenger's door switch

• Malfunction of the ETACS-ECU

• Damaged harness wires and connectors

DIAGNOSTIC PROCEDURE

Step 1. ECU check by using the SWS monitor
Check that the power supply and earth lines to the 
ETACS-ECU and the SWS communication lines are 
normal.

• Ignition switch: ON

ECU TO BE CHECKED

• ETACS ECU

OK: "OK" is displayed on the "ETACS ECU" 
menu.

Q: Is the check result normal?

YES : 

Go to Step 2.

NO : 

Refer to Inspection Procedure A-3 
"Communication with the ETACS-ECU is 
not possible
