Remote Up / Down Function Does Not Operate

WINDOW / GLASS: POWER WINDOW CONTROL SYSTEM: Remote Up / Down Function does not Operate; 2013 MY FR-S [03/2012 -]
- Remote Up / Down Function does not Operate

DESCRIPTION

With the ignition switch ON, the power window regulator master switch assembly transmits remote operation signals to each power window regulator switch assembly. Then, the power window regulator switch assembly drives each power window regulator motor assembly.

WIRING DIAGRAM

Refer to DTCs B2312 and B2315 B2312.

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.
