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 ignition switch is turned from ON to off by receiving operation permission signals from the main body ECU (driver side junction block assembly).

• However, when approximately 45 seconds have elapsed, or the driver side door or front passenger side door is opened within approximately 45 seconds of the ignition switch being turned off, the power window regulator motor assembly stops operating.

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