    Door control transmitter

    • Contains lock, unlock, and panic switches.*1

    • Transmits weak electric waves (recognition codes and function codes) to door control receiver.

    • Illuminates indicator light (LED) during transmission.
    Door control receiver Receives weak electric waves (recognition codes and function codes) from door control transmitter via electrical key antenna and changes waves to code data.

    • The built-in motor open the door.*2

    • The built-in motor open/close the door.*3

    • Performs the back door open operation according to the door lock position determination of the main body ECU (multiplex network body ECU).*2

    • Performs the back door open/close operation according to the door position as determined by the power back door ECU.*3
    Door lock position switch Transmits door lock positions of each door to main body ECU (multiplex network body ECU).
    Wireless door lock buzzer Emits beep (answer-back) when doors are locked or unlocked by wireless operation (except Europe and China).
    Certification ECU (smart key ECU assembly) Matches code data with registered code and outputs code data to main body ECU (multiplex network body ECU).

      Function Outline
      All door lock function Pressing the lock switch locks all the doors and retracts the outer mirrors.

      All door unlock function

      Tech Tips

      This function can be enabled by changing the customize parameter.

      		 Pressing unlock switch unlocks all the doors and returns the outer mirrors.
      2-step unlock function

      Pressing the unlock switch once unlocks only the driver side door and returns the outer mirrors.

      Pressing the unlock switch twice within 3 seconds unlocks all the doors.
      Power window and sliding roof open function After locking all the doors with the door control transmitter operation, pressing the unlock switch for 3 seconds or more opens all the power windows and the sliding roof.
      Power window and sliding roof close function After locking all the doors with the door control transmitter operation, pressing the unlock switch for 3 seconds or more closes all the power windows and the sliding roof.
      Chattering prevention function If a switch is pressed, the corresponding switch operation is performed once. If a switch is held down, the corresponding switch operation occurs only once and does not repeatedly activate. Lastly, when pressing a switch at 1 second intervals, the corresponding operation activates once for every press of the switch.

      Answer-back function

      - Buzzer answer-back (except Europe and China)

      - Hazard answer-back (except China)

      • When the doors are locked, the turn signal lights flash once. When the doors are unlocked, the turn signal lights flash twice and the wireless warning buzzer sounds twice.

      • When the transmitter is used for opening the power windows and sliding roof, this function causes the buzzer to sound to indicate that the operation begins.
      Automatic lock function If no doors are opened within 30 seconds after they are unlocked by the door control transmitter, all the doors will lock again automatically.
      Panic alarm function*1 Holding down the panic switch for more than 1 second sets off the theft deterrent alarm (the horn and security horn sound, the hazard warning lights, headlights, and taillights flash, and the map light and spot light illuminate).
      Fail-safe function When the key is in the vehicle, the doors cannot be locked by the lock switch.
      Illuminated entry function

      • Pressing the unlock switch causes dome light (map light and rear map light), side step light and outer mirror foot light illumination and all door unlock operation to occur simultaneously.

      • If the doors have not been opened, the dome light (map light and rear map light), side step light and outer mirror foot light turns off in approximately 15 seconds.
      Door ajar warning function (except China) If any door is open or ajar, pressing the lock switch will cause the wireless door lock buzzer to sound for approximately 5 seconds.
      Memory call function If the unlock switch of a memory call registered transmitter is pressed and the driver door is opened, the following parts move to the memory call position: front seat, front seat belt anchor, steering wheel and outer mirrors.
      Transmitter recognition code registration function Enables 7 modes for registering (writing and storing) transmitter recognition codes in the EEPROM.
      Wireless power back door open/close function*2 When the back door switch is pressed for 0.8 seconds or more, the back door opens/closes. (Power back door operation changes according to the customize parameters. For details, refer to the Power Back Door System.)
