window system.
• Disconnection and connection of battery cable from negative terminal.
• When power window main switch replaced.
• Electric power supply to power window main switch or power window motor (driver side) is interrupted by
blown fuse or disconnection and connection of the negative terminal of battery, etc.
• Disconnection and connection of power window main switch harness connector.
• Removal of power window motor (driver side) from regulator assembly.
• Operation of regulator assembly as an independent unit.
• Removal and installation of glass.
• Removal and installation of door glass run.
CAUTION:
The following specified operations can not be performed under the non-initialized condition.
• Auto-up operation
• Anti-pinch function
Work Procedure

ANTI-PINCH INSPECTION
ANTI-PINCH INSPECTION
Description
INFOID:0000000009757230
If any of the following operations are performed, the initialization is necessary for normal operation of anti-
pinch function.
• Disconnection and connection of battery cable from negative terminal.
• When power window main switch replaced.
• Electric power supply to power window main switch or power window motor (driver side) is interrupted by
blown fuse or disconnection and connection of the negative terminal of battery, etc.
• Disconnection and connection of power window main switch harness connector.
• Removal of power window motor (driver side) from regulator assembly.
• Operation of regulator assembly as an independent unit.
• Removal and installation of glass.
• Removal and installation of door glass run.
Work Procedure
INFOID:0000000009757231
1.
CHECK ANTI-PINCH FUNCTION
1. Fully open the door window.
2. Place a piece of wood near fully closed position.
3. Close door glass completely with AUTO-UP.
4. Check the following conditions.
-
Check that glass lowers for approximately 150 mm (5.91 in.) without pinching piece of wood and stops.
-
Check that glass does not rise not when operating the power window main switch while lowering.
CAUTION:
•
Perform initial setting when AUTO-UP operation or anti-pinch function does not operate nor-
mally.
•
Check that AUTO-UP operates before inspection when system initialization is performed.
•
Do not check with hands and other body parts because they may be pinched. Do not get
pinched.
