2020 Toyota RAV4 XLE, AWDSECTION System Description [10/2019 - 10/2022]
  1. OUTLINE 
    1. Remote Connect, which enables the user to check the vehicle status and operate the vehicle from a remote location, has been used.
    2. Remote Connect is available by installing a dedicated smartphone application after entering a service contract*.
      1. *: Remote Connect cannot be operated until the user has entered a service contract.
    3. Remote Connect services are performed through data communication between mainly a Remote Connect capable DCM (telephone transceiver assembly), the service center and a smartphone with the application installed.

      HINT: 

      • Start and operate the Remote Connect system according to the instructions displayed on the application.
      • The contents of Remote Connect may vary depending on the application.
      • For details on available Remote Connect, go to http://www.toyota.com/audio-multimedia/
  2. FUNCTION OF MAIN COMPONENTS 
    Component Function
    DCM (Telephone Transceiver Assembly)
    • Sends vehicle information signals to the service center.
    • Receives remote operation signals from the service center and sends them to each ECU.
    Telephone and GPS Antenna (No. 1 Amplifier Antenna Assembly) GPS Antenna Receives signals from GPS satellites and transmits these signals to the DCM (telephone transceiver assembly).
    Telephone Antenna (Main) Transmits signals from the DCM (telephone transceiver assembly) and receives signals from the service center. (Connect as main)
    Telephone and GPS Antenna (Navigation Antenna Assembly) Telephone Antenna (Sub) Receives signals from the service center. (Connect as sub)
    Certification ECU (Smart Key ECU Assembly) Receives the remote engine start and stop signal from the user's smartphone or electrical key transmitter sub-assembly via the DCM (telephone transceiver assembly) and initiates the engine start operation.
    Air Conditioning Amplifier Assembly
    • Sends ambient temperature signals to the DCM (telephone transceiver assembly).
    • Operates the air conditioning system and/or rear defogger after the engine has been started by remote operation, based on signals from the DCM (telephone transceiver assembly).
    Main Body ECU (Multiplex Network Body ECU) Locks the door when a remote door lock and unlock operation signal is received.
  3. FUNCTION 
    1. The main services of Remote Connect are as follows:
      Category Remote Service Function
      Remote Information Vehicle Status Report Allows the vehicle status (doors open/closed, etc.) and vehicle information (distance traveled, etc.) to be checked from a remote location via a smartphone, after the ignition switch has been turned off. By updating the information, the latest vehicle status can be displayed.*1
      Remote Notification Guest Driver Monitor
      • Allows the user to set limits on the vehicle speed, traveling time, etc. when a guest driver (a family member, valet, etc.) is driving the vehicle, via a smartphone.
      • If the guest driver exceeds a user set limit, a notification will be sent to the user so the driving status can be monitored.*2*3
      Vehicle Status Alerts Sends a notification to the user if certain operations are not performed within a certain amount of time after the ignition switch is turned off, such as locking the doors, closing the windows, etc.*2*4
      Remote Operation Remote Engine Start and Stop
      • Allows the user to start the engine and keep it running for a certain amount of time from a remote location via a smartphone or the electrical key transmitter sub-assembly. Performing the remote stop operation after the remote start operation has been performed changes the vehicle to the ignition switch off condition.*5
      • Starts the air conditioning system when the engine is remotely started, if the air conditioning system was on when the ignition switch was last turned off.
      • The air conditioning system or rear defogger may be operated by signals from the service center depending on the ambient temperature.
      Remote Door Lock and Unlock Allows the doors to be locked/unlocked from a remote location via a smartphone.*6
      1. *1: If the latest vehicle information has not been sent from the vehicle due to the condition of the vehicle (such as if the DCM (telephone transceiver assembly) is outside of the cellular telephone reception area), the most recently received information will be displayed.
      2. *2: No notifications will be sent if the latest vehicle information has not been sent from the vehicle due to the condition of the vehicle (such as if the DCM (telephone transceiver assembly) is outside of the cellular telephone reception area). Notifications may be delayed if the smartphone has poor reception.
      3. *3: Only one notification per set condition will be sent during a single trip.
      4. *4: If the smart key system has been canceled, vehicle status alerts notifications will not be sent to the user. If the electrical key transmitter sub-assembly is inside the vehicle or detected as being "inside cabin", vehicle status alerts notifications will not be sent.
      5. *5: If the vehicle cannot receive the remote engine start and stop signal due to the condition of the vehicle (such as if the DCM (telephone transceiver assembly) is outside of the cellular telephone reception area), the engine will not be started remotely. Additionally, the remote engine start and stop operation signal may not be received depending on vehicle conditions.
      6. *6: If the vehicle cannot receive a door lock/unlock signal due to the condition of the vehicle (such as if the DCM (telephone transceiver assembly) is outside of the cellular telephone reception area), the door lock or unlock operation will not be performed. After a door unlock operation is performed, if the doors are not opened within a certain amount of time, the doors will automatically be locked.
