POWER WINDOW CONTROL SYSTEM (for Models with Jam Protection Function on Driver Door Window Only) - Key-off Operation Function Operates even if Operating Conditions are not Satisfied


DESCRIPTION

  1. When the front doors are closed, each power window regulator motor 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.
  1. 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 stops operating.
  1. During the auto function operation, when 45 seconds have passed and key-off operation is prohibited, the window operation stops immediately.
