DETECTION CONDITION POSSIBLE CAUSE
No.6 DOOR GLASS REVERSES EVEN THOUGH THE GLASS DOES NOT ENCOUNTER A FOREIGN OBJECT WHILE IT IS MOVING UP IN AUTOMATIC MODE [POWER WINDOW SYSTEM]
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.
| 6 | 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. |
