PERFORM DTC CONFIRMATION PROCEDURE

Perform DTC Confirmation Procedure for the displayed DTC, and then check that DTC is detected again.

At this time, always connect CONSULT to the vehicle, and check diagnostic results in real time.

If two or more DTCs are detected, refer to

and determine trouble

diagnosis order.

NOTE:

• Freeze frame data is useful if the DTC is not detected.

• Perform Component Function Check if DTC Confirmation Procedure is not included in Service Manual. This

simplified check procedure is an effective alternative though DTC cannot be detected during this check.

3. Close door glass completely with AUTO-UP.

• 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

PWC-53, "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.
