- When a key switch is pushed: 1) the door control receiver assembly receives the key signal; 2) the door control receiver assembly sends a signal to the certification ECU (smart key ECU assembly); 3) the main body ECU (multiplex network body ECU) sends the operation permission signal to the power window regulator motor assembly; and 4) the power window regulator motor assemblies are activated.
- When the driver door key cylinder (key linked switch) is turned: 1) the door lock motor receives the signal; 2) the main body ECU (multiplex network body ECU) sends the signal to the power window regulator motor assembly; and 3) the power window regulator motor assemblies are activated.
- 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).
- 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.
- During an auto operation, when 43 seconds have passed and key-off operation is prohibited, the window operation stops immediately.
If a door glass or a power window regulator motor assembly does not operate smoothly, the jam protection function may be triggered automatically, resulting in the auto up function being unable to fully close the window.

This symptom may occur for any of the windows.
This symptom may occur for any of the windows.
The jam protection function operates within a specified range during the manual up or auto up operation.
