POWER WINDOW CONTROL SYSTEM Key-off Operation Function Operates even if Operating Conditions are not Satisfied

DESCRIPTION

• When the front doors are closed, each power window regulator motor assembly can control its power window operation for approximately 45 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 45 seconds have elapsed, or the driver door or front passenger door is opened within approximately 45 seconds of the power switch being turned off, the power window regulator motor assembly stops operating.

• During an auto operation, when 45 seconds have passed and key-off operation is prohibited, the power window continues operating until the auto operation is completed.
