WINDOW / GLASS: POWER WINDOW CONTROL SYSTEM: PRECAUTION; 2013 MY FR-S [03/2012 -]

1. POWER WINDOW CONTROL SYSTEM PRECAUTIONS

NOTICE:
* The power window control system uses a LIN communication system. Inspect the communication function by following How to Proceed with Troubleshooting LIN Communication System. Troubleshoot the power window control system after confirming that the communication system is functioning properly.
* The power window control system prohibits the AUTO UP/DOWN function when the jam protection function malfunctions. Therefore, troubleshoot the power window control system after confirming that no diagnostic codes are displayed.
* When the power window regulator master switch assembly, power window regulator switch assembly and power window regulator motor assembly is 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.
* The jam protection function may operate unexpectedly even when the power window control system is normal, due to detection of a different operation learned value when the door glass moving speed changes sharply under any of the following conditions:
(1) A power window is opened or closed while the vehicle is being driven on a rough road.
(2) A power window is opened or closed while the door is being opened or closed.
(3) A sharp voltage change.
* Do not disconnect the battery while the ignition switch is ON. Otherwise, the power window system may have a malfunction.
