POWER WINDOW CONTROL SYSTEM(w/ Jam Protection Function) Key-off Operation Function Operates even if Operating Conditions are not Satisfied

DESCRIPTION

• When the driver door or front passenger door are closed, each power window regulator motor 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 front power window regulator motor assembly LH (for LHD) or front power window regulator motor assembly RH (for RHD) stops operating.

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