- Key-off Operation Function Operates even if Operating Conditions are not Satisfied
DESCRIPTION
* When the driver or front passenger side door has not been opened, driver or front passenger side door power window regulator motor can control its power window operation for approximately 45 seconds after the ignition switch is turned from ON to off (the key is removed) by receiving operation permission signals from the main body ECU (network gateway ECU). However, when approximately 45 seconds have elapsed, or the driver or front passenger side door is opened within approximately 45 seconds after turning the ignition switch off (the key is removed), the power window regulator motor stops operating.
During the AUTO function operation, the window operation will continue until complete even if 45 seconds have elapsed or a door is opened.
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.
