  1. GENERAL


    • The blind spot monitor system is a function that assists the driver when changing lanes. The function uses quasi-millimeter wave radar to detect vehicles that are traveling in an adjacent lane in the area that is not reflected in an outer rear view mirror assembly with cover. The function advises the driver of the existence of a vehicle by illuminating the outer rear view mirror indicator on the outer rear view mirror assembly with cover.

    • If the turn signal switch is operated while the outer rear view mirror indicator on an outer rear view mirror assembly with cover is illuminated, the indicator starts blinking to give additional warning to the driver.

  2. FUNCTION OF COMPONENTS

    Component Function
    Blind Spot Monitor Sensor

    • Consists of a 24 GHz radar module and an integrated processing module.

    • Illuminates or blinks the outer rear view mirror indicator on an outer rear view mirror assembly with cover.

    • Sounds the RCTA buzzer (blind spot monitor buzzer) when the RCTA function is operating.

    • Changes the outer rear view mirror indicator on an outer rear view mirror assembly with cover from illuminated to blinking when a turn signal switch operation signal is received from the combination meter assembly with the blind spot monitor system operating.

    • Dims the outer rear view mirror indicator on the outer rear view mirror assembly with cover.

    • Displays the RCTA icon on the multi-display when the RCTA function is operating.

    Outer Rear View Mirror Assembly With Cover


    • Outer Mirror (Outer Rear View Mirror Indicator)

    		 Turns on or blinks the indicator based on a signal from the blind spot monitor sensor.
    Steering Pad Switch Assembly Enables, disables or cuts off the operation of the blind spot monitor system by transmitting switch operation signals to the combination meter assembly.
    RCTA Buzzer (Blind Spot Monitor Buzzer) Sounds based on a signal from the blind spot monitor sensor.

    Combination Meter Assembly


    • Multi-information Display

    • Transmits a turn signal switch operation signal from the headlight dimmer switch assembly to the blind spot monitor sensor via CAN communication.

    • Displays an error message on the multi-information display if the blind spot monitor sensor detects a malfunction while it is operating.
    Main Body ECU (Multiplex Network Body ECU) Transmits the destination information and the dimmer signal to the blind spot monitor sensors via CAN communication.
    Skid Control ECU Transmits a vehicle speed signal to the blind spot monitor sensors via CAN communication.
    ECM Transmits a shift position signal (R) to the blind spot monitor sensors via CAN communication.
    Steering Sensor Detects the angle of the steering wheel and transmits the resulting signals to the blind spot monitor sensors via CAN communication.

    Airbag Sensor Assembly


    • Yaw Rate and Acceleration Sensor

    		 Transmits the yaw rate signal to the blind spot monitor sensor via CAN communication.
    Rear Television Camera Assembly Receives the blind spot monitor sensor information via CAN communication and sends it to the multi-display through the video signal cable.
    Radio and Display Receiver Assembly Receives the video signals from the rear television camera assembly and displays the RCTA icon on the display panel.

  3. OPERATION DESCRIPTION


    1. Operation description of the blind spot monitor system


      1. Operation conditions:


        • The blind spot monitor system is on.

        • The shift lever is in any position other than R.

        • Vehicle speed is more than approximately 16 km/h (10 mph).

      2. Conditions in which a sensor can detect a vehicle

        The blind spot monitor system indicates detection of a vehicle in the detection area when either condition is met:


        • When a vehicle is detected in an adjacent lane overtaking this vehicle.

        • When a vehicle is detected entering the detection area because it changed lanes.

    2. Operation description of the RCTA function


      1. Operation conditions:


        • The RCTA function is on.

        • The shift lever is in R.

        • The vehicle speed is less than approximately 8 km/h (5 mph).

      2. Conditions in which a sensor can detect a vehicle

        The RCTA function indicates detection of a vehicle in the detection area when both conditions are met:


        • A vehicle is approaching from the right or left at the rear of the vehicle.

        • The vehicle speed is approximately 8 km/h (5 mph) to 28 km/h (18 mph).

  4. OPERATION OF OUTER REAR VIEW MIRROR INDICATOR AND RCTA BUZZER (BLIND SPOT MONITOR BUZZER)


    1. Initial check


      1. When the blind spot monitor system is turned on with the engine switch on (IG), the outer rear view mirror indicators on the outer rear view mirror assembly with cover illuminate for 3 seconds.

      2. When the RCTA function is turned on with the engine switch on (IG), the outer rear view mirror indicators on the outer rear view mirror assembly with cover illuminate for 3 seconds and the RCTA buzzer (blind spot monitor buzzer) sounds for 1 second.

      3. When the engine switch is turned from off to ON with the blind spot monitor system on, the outer rear view mirror indicators on the outer rear view mirror assembly with cover illuminate for 3 seconds.

    2. Operation for each function

        Operation for blind spot monitor system


        • When a sensor detects a vehicle in the blind spot area, the outer rear view mirror indicator on the outer rear view mirror assembly with cover illuminates.

        • If the turn signal switch is operated while the sensor is detecting a vehicle in the detection area and the outer rear view mirror indicator on the outer rear view mirror assembly with cover is illuminated, the indicator starts blinking as shown in the illustration.
