      Door Courtesy Light Switch Assembly Detects whether the doors are open or closed and sends this information to the main body ECU (multiplex network body ECU).
      Door with Motor Lock Assembly Door Lock Position Switch Detects whether the doors are locked or unlocked and sends this information to the main body ECU (multiplex network body ECU).
      Door Lock Motor Drives the motor in response to signals from the main body ECU (multiplex network body ECU) and locks or unlocks the doors.
      Key-linked Switch Sends a lock or unlock request signal to the main body ECU (multiplex network body ECU) by the mechanical key*1 or ignition key*2.
      Double Lock Motor*3 Drives the motor by signals from the double lock door control relay assembly and activates or cancels the double locking system.
      Double Lock Position Switch*3 Detects the operating conditions of the double lock motor and sends this information to the double lock door control relay assembly.
      Back Door Lock Assembly Back Door Courtesy Light Switch Detects whether the back door is open or closed and sends this information to the main body ECU (multiplex network body ECU).
      Door Lock Motor Drives the motor in response to signals from the main body ECU (multiplex network body ECU) and releases the back door latch.

      Unlock Warning Switch Assembly*2 Detects whether or not the ignition key is inserted into the ignition key cylinder and sends this information to the main body ECU (multiplex network body ECU).
      Combination Meter Assembly Receives signals from the speed sensor and sends the vehicle speed signal to the main body ECU (multiplex network body ECU).
      Main Body ECU (Multiplex Network Body ECU)

      • Drives all door lock motors in response to signals.

      • Sends an operation request signal to the double lock door control relay assembly in response to each signal.*3
      Certification ECU (Smart Key ECU Assembly)*1 Sends the back door opener switch signals to the main body ECU (multiplex network body ECU).

  2. FUNCTION


    1. The power door lock control system has the following functions:

      Function Outline
      Manual Lock and Unlock This function can lock or unlock all doors by operation of the door lock switch.
      Manual Unlock Prohibition Performing the door lock operation with a door control transmitter *1 or an electrical key transmitter *2 will prohibit the doors from being unlocked by the door lock control switch.
      Key-linked Lock and Unlock This function, linked with the driver door key cylinder, can lock or unlock all the doors when a lock or unlock operation is effected.
      Key Confinement Prevention When the key is inserted in the ignition key*3 cylinder and the door lock operation is performed while the driver door is open, all the doors will be unlocked.
      Back Door Open Pressing the back door opener switch when the back door is unlocked will open the back door.
      Double Locking System*3

      • The double locking system also prevents the doors from being opened through the operation of the inside door knobs. Thus, the doors cannot be opened from either inside or outside of the vehicle.

      • Pressing the "lock" button on the door control transmitter *1 or electrical key transmitter *2 once then pressing it again within 5 seconds activates the double locking system. However, as an emergency unlocking maneuver, only the driver door can be unlocked with a key.

      Note

      Never activate the double locking system when there are people in the vehicle because the doors cannot be opened from the inside of the vehicle. If locking the doors by accident, press the "unlock" button of the door control transmitter*1 or electrical key transmitter*2.
