Auto Up Operation Does Not Fully Close Power Window (Jam Protection Function Is Activated)

WINDOW / GLASS: POWER WINDOW CONTROL SYSTEM: Auto Up Operation does not Fully Close Power Window (Jam Protection Function is Activated); 2013 MY FR-S [03/2012 -]
- Auto Up Operation does not Fully Close Power Window (Jam Protection Function is Activated)

DESCRIPTION

If a door glass or a power window regulator motor assembly does not operate smoothly, the jam protection function may be triggered automatically, resulting in the auto up function being unable to fully close the window.

INSPECTION PROCEDURE

NOTICE:
* When the power window regulator master switch assembly, power window regulator switch assembly and power window regulator motor assembly is reinstalled or replaced, the power window control system must be initialized Programming and Relearning.
* After the door glass or weatherstrip, etc. have been replaced, if AUTO UP is performed at the position where the work was performed, a different window movement speed to the standard operating learning value may be detected, causing the jam protection function to operate. When the jam protection function malfunctions and prevents the door glass from closing completely, the following procedure can be used to cancel the jam protection function and allow the door glass to be closed*1.
* Repeat the AUTO UP maintain -> jam protection function operation twice in succession*2.
* The third repeat of the AUTO UP maintain operation will cause the position of the upper edge of the door glass to be relearned, allowing the door glass to be closed.
* *1: In some cases, the state of the door glass or regulator may prevent the glass from being closed, even in this mode.
* *2: If any action other that the AUTO UP operation (DOWN operation, IG OFF, timer operated OFF, index operation, etc.) is performed between the operation of the jam protection function and the AUTO UP maintain, this count will be reset.

PROCEDURE

1. PERFORM INITIALIZATION (APPLICABLE LOCATION)

(a) Initialize the power window regulator motor assembly (applicable location) Programming and Relearning.

(b) Check that all the power windows move when the auto up and down function of the power window regulator master switch assembly and power window regulator switch assemblies are operated Operation Check.

OK:

Auto up and down function is normal

NG -- CHECK WINDOW GLASS SLIDING MOVEMENT (APPLICABLE LOCATION)

OK -- END (PROBLEM DUE TO INITIALIZATION FAILURE)

2. CHECK WINDOW GLASS SLIDING MOVEMENT (APPLICABLE LOCATION)

(a) Remove the window regulator motor assembly.

(b) Install the window glass onto the weatherstrip.

(c) Check if the door window regulator operates smoothly.

(d) Check that the window glass slides smoothly when sliding it up by hand.

OK:

Door window glass slides smoothly.

CAUTION:
Perform initialization again.

HINT
Ensure the following:

* The window glass fits with the weatherstrip without improper contact or deformation.
* Foreign objects are not caught in the weatherstrip.

NG -- FIT WINDOW GLASS CORRECTLY (REMOVE FOREIGN OBJECTS CAUSING IMPROPER FIT OR REPLACE PARTS)

OK -- REPLACE POWER WINDOW REGULATOR MOTOR ASSEMBLY Removal
