Power Window Initialization Procedure
- Switch the ignition to ON.
- Press the power window switch and fully open the suspect door glass.
- Pull up the power window main switch/sub switch to the manual-up position to fully close the suspect door glass, and keep holding the switch up at the position for approx.2 s.
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 door glass cannot be operated automatically.
1 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 4-7 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 8-12 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

NO.2 DOOR GLASS DOES NOT REVERSE, EVEN WHEN ENCOUNTERING A FOREIGN OBJECT IN ITS PATH [POWER WINDOW SYSTEMS (AUTO-OPEN/CLOSE FUNCTION)]
Note. Perform the following inspection for the power window system component parts of the windows where the door glass does not reverse, even when encountering a foreign object in its path.
| 2 | Door glass does not reverse, even when encountering a foreign object in its path. |
|---|---|
| POSSIBLE CAUSE | Automatic window return range did not reset after battery disconnection: Step 2 |
NO.3 DOOR GLASS REVERSES EVEN THOUGH THE GLASS DOES NOT ENCOUNTER A FOREIGN OBJECT WHILE IT IS MOVING UP 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 door glass reverses even though the glass does not encounter a foreign object while it is moving up in automatic mode.
3 Door glass reverses even though the glass does not encounter a foreign object while it is moving up in automatic mode. POSSIBLE CAUSE Extreme change in the sliding resistance of the glass while the door glass is closing. Improper installation of the acrylic door visor. Power window motor malfunction Object caught between the glass run channel and the door glass. Insufficient tightening of the door glass to the carrier plate. Glass run channel malfunction. Glass guide related malfunction. NOTE: The auto-reverse pinch protection function is a mechanism that automatically reverses (opens) the door glass while it is closing when the power window main switch detects the signal from the power window motor indicating that an object is obstructing the door glass movement. The auto-reverse pinch protection function may operate if the sliding resistance of the door glass increases causing the closing speed to decrease. If the door glass closing speed has changed, concentrate the inspection on the following locations: (Slip occurrence) If the door glass is slipping forward, inspect the front side of the glass guide or glass run channel. If the door glass is slipping rearward, inspect the rear side of the glass guide or glass run channel
