Key-off Operation Function Operates even if Operating Conditions are not Satisfied [08/2013 - ]: Description

WARNING: This page is about a different car, the 2014 Lexus ES 300h. However, it is still accessible from the selected car via links, so may be relevant.

When the front doors are closed, each power window regulator motor assembly can control its power window operation for approximately 43 seconds after the power switch is turned from on (IG) to off by receiving operation permission signals from the main body ECU (multiplex network body ECU).
However, when approximately 43 seconds have elapsed, or the driver door or front passenger door is opened within approximately 43 seconds of the power switch being turned off, the power window regulator motor assembly stops operating.
During auto operation, when 43 seconds have elapsed and key-off operation is prohibited, the window operation stops immediately.
