DOOR LOCK AND UNLOCK SWITCH
• Check that glass lowers for approximately 150 mm (5.91 in) or 2 seconds without pinching piece of wood
and stops.
• Check that glass does not rise when operating the main power window and door lock/unlock switch while
lowering.
CAUTION:
• Do not check with hands and other parts of the 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 set-
ting in that situation. Refer to
• Perform initial setting when auto-up operation or anti-pinch function does not operate normally.
• Finish initial setting. Otherwise, next operation cannot be done.
