Note
• Perform the following inspection for the power window system component parts of windows where the
front door glass cannot be operated automatically.
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).
