SYMPTOM TROUBLESHOOTING [POWER WINDOW SYSTEMS (AUTO-OPEN/
Two-step Down Function Inspection
• The distance the door glass opens can be changed using the two-step down function (approx. 20— 100 mm
{0.79— 3.93 in}).
• The two-step down function can be made inoperative. (The function is operative at the initial setting.)
• The two-step down function does not function during IG OFF timer.
Note
• Perform the following inspection for the power window main switch and the power window subswitches for
each front window.
STEP
• Turn the ignition switch to the ON position.
1
• 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.)
End Of Sie
No.1 DOOR GLASS DOES NOT MOVE UP AND DOWN IN AUTOMATIC MODE[POWER WINDOW SYSTEMS
(AUTO-OPEN/CLOSE FUNCTION)]
Note
• Perform the following inspection for the power window system component parts of windows where the
front door glass cannot be operated automatically.
1 Door glass does not move up and down in automatic mode
• 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
POSSIBLE
supply malfunctions.
CAUSE
• Sensor 1 and/or 2 malfunction
— When the door glass is moving up and down, the power window switch cannot sense a pulse
— When the door glass is moving up and down, the switch cannot sense a pulse signal from sensor
— 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.
