POWER WINDOW CONTROL SYSTEM(for Models with Jam Protection Function on 4 Windows) Key-off Operation Function Operates even if Operating Conditions are not Satisfied

DESCRIPTION

• When the front doors are closed, each door window regulator assembly can control its power window operation for approximately 43 seconds after the ignition switch is turned from ON 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 ignition switch being turned off, the door window regulator assembly stops operating.

• During auto operation, when 43 seconds have elapsed and key-off operation is prohibited, the window continues the operation until the auto operation is completed.
