cial Repair Requirement
INFOID:0000000009460831
INITIALIZATION PROCEDURE
1. Disconnect battery minus terminal or power window ma in switch connector. Reconnect it after a minute or
more.
2. Turn ignition switch ON.
3. Operate power window switch to fully open the wi ndow. (This operation is unnecessary if the window is
already fully open)
4. Continue pulling the power window switch UP (AUTO-UP operation). Even after glass stops at fully closed
position, keep pulling the switch for 4 seconds or more.
5. Inspect anti-pinch function.
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 inspectio n when system initialization is performed.
• It may switch to fail-safe mode if open/close oper ation is performed continuously. Perform initial set-
ting in that situ ation. Refer to PWC-11, "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.
1. Auto-up operation
2. Anti-pinch function
3. Retained power operation wh en ignition switch is OFF.
