for Preparation Click here


DESCRIPTION

  1. 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).
  2. However, when approximately 43 seconds have elapsed, or the driver side door or front passenger side door is opened within approximately 43 seconds of the power switch being turned off, the power window regulator motor assembly stops operating.
  3. During an auto operation, when 43 seconds have passed and key-off operation is prohibited, the window continues the operation until the auto operation is completed.
