Wireless Transmitter-linked Function*
- When a key switch is pushed: 1) the door control receiver receives the wireless door lock signal; 2) the door control receiver sends a signal to the main body ECU (multiplex network body ECU) through 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 assembly are activated.
- *: w/ Side Marker Light
Key-linked Function
- 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 assembly 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 engine 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 door or front passenger door is opened within approximately 43 seconds of the engine switch being turned off, the power window regulator motor assembly stops operating.
- During auto operation, when 43 seconds have elapsed 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 operation being unable to fully close the window.
HINT
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.
