INITIALIZATION PROCEDURE
1. Disconnect battery minus terminal or power window main switch connector. Reconnect it after a minute or more.

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.
• Check that glass lowers for approximately 150 mm or 2 seconds without pinching piece of wood and stops.
• Check that glass does not rise when operating the power window main switch while lowering. CAUTION: • Do not check with hands and other part of body because they may be pinched. Do not get pinched.
• Check that AUTO-UP operates before inspection when system initialization is performed.
• It may switch to fail-safe mode if open/close operation is performed continuously. Perform initial setting in that situation. Refer to PWC-345, "Fail Safe".
• Perform initial setting when auto-up operation or anti-pinch function does not operate normally.
• Finish initial setting. Otherwise, next operation cannot be done.
