STEP

INSPECTION

ACTION

1

• Turn the ignition switch to the ON position.

• Raise door glass completely.

• When the door glass is lowered using 

manual mode, does it move down to approx. 
30 mm {1.2 in} from the completely closed 
position and stop for 1 s? (This inspection 
cannot be performed during IG OFF timer 
function operation.)

Yes

• Two-step down function is normal. 

• Reinspect malfunction symptoms.

No

• Perform the power window initial setting procedure and 

verify auto-up/down operation.(See 09-12-13 POWER 
WINDOW INITIALIZATION PROCEDURE.)
— If the automatic function does not operate, go to 

Automatic Door Glass Return Function Inspection.

— If the automatic function operates but the two-step 

down function does not, replace the power window 
switch.

Door glass does not move up and down in automatic mode

POSSIBLE 

CAUSE

• Open circuit or short to power supply in sensor 1 signal, ground signal from wiring harness (between 

power window switch and power window motor), inner power window switch, or inner motor: Steps 3–6

• Open circuit or short to power supply/ground in sensor 2 signal from wiring harness (between power 

window switch and power window motor), inner power window switch, or inner motor: Steps 7–11

Note

• The automatic function and the IG OFF timer function do not operate while the power window switch 

is in fail-safe mode. The fail-safe operates when sensor 1, and/or sensor 2, and/or the sensor power 
supply malfunctions.

• Sensor 1 and/or 2 malfunction

— When the door glass is moving up and down, the power window switch cannot sense a pulse 

signal from sensor 1 during the time it senses 5 pulses (2.5 cycles) from sensor 2.

— When the door glass is moving up and down, the switch cannot sense a pulse signal from sensor 

2 during the time it senses 5 pulses (2.5 cycles) from sensor 1. 

— There are three abnormal pulses in a pulse signal while the door glass is moving up or down.

— There are 20 cycle pulses from a closed position while the door glass is moving up.

— There is no pulse signal for 1 s after the door glass is moved down.

Diagnostic procedure

STEP

INSPECTION

ACTION

1

INSPECT WHETHER POWER WINDOW 
SWITCH ENTERS FAIL-SAFE MODE OR NOT

• Did the door glass move up or down in 

automatic mode?

Yes

Reinspect malfunction symptoms.

No

Go to the next step. (Power window switch may enter fail-
safe mode.)

2

VERIFY WHETHER MALFUNCTION IS IN 
WIRING HARNESS (BETWEEN POWER 
WINDOW SWITCH AND FRONT POWER 
WINDOW MOTOR) OR ELSEWHERE

• Turn the ignition switch to the ON position.

• Inspect the voltage at the following front 

power window switch terminals (sensor 1 
signal):
— Driver’s side (at main switch): 2C

— Passenger’s side (at sub-switch): J

• Does the voltage alternate between 0 V and 

approx. 12 V when the door glass is moving 
up and down?

Yes

Go to Step 7. 

No

Go to the next step.

3

VERIFY SENSOR 1 OUTPUT SIGNAL

• Turn the ignition switch to the ON position.

• Inspect the voltage at the following front 

power window motor terminals (sensor 1 
signal):
— Driver’s side: A

— Passenger’s side: A

• Is the voltage alternate between 0 V and 

approx. 12 V when the door glass is moving 
up and down in manual mode?

Yes

Go to the next step.

No

Replace the power window motor, then go to Step 12. 

4

INSPECT WIRING HARNESS BETWEEN 
POWER WINDOW SWITCH AND POWER 
WINDOW MOTOR FOR CONTINUITY

• Turn the ignition switch to the LOCK position.

• Disconnect the power window switch 

connector.

• Is there continuity between the following   

front power window switch terminals and 
front power window motor terminals?
— Driver’s side (at main switch— power 

window motor):

• 2C— A (sensor 1 signal)

• 2B— D (sensor power supply)

• 2A— C (ground signal)

— Except driver’s side (at sub-switch— 

power window motor):

• J— A (sensor 1 signal)

• B— D (sensor power supply)

• D— C (ground signal)

Yes

Go to the next step.

No

Repair the wiring harness between the power window 
switch and power window motor, then go to Step 12.

5

VERIFY WHETHER MALFUNCTION IS IN 
WIRING HARNESS (BETWEEN POWER 
WINDOW SWITCH AND POWER WINDOW 
MOTOR) OR POWER WINDOW SWITCH

• Turn the ignition switch to the ON position.

• Inspect the voltage at the following power 

window switch terminals:

— Driver’s side (at main switch)

• 2C (sensor 1 signal)

• 2A (ground signal)

— Passenger’s side (at sub-switch)

• C (sensor 1 signal)

• I (ground signal)

• Is the voltage approx. 12 V?

Yes

Repair the wiring harness between the suspect power 
window switch and power window motor, then go to Step 
12.

No

Replace the suspect power window switch (open circuit or 
short to power supply in power window switch).
