BLIND SPOT MONITOR SYSTEM


  1. FUNCTION OF MAIN COMPONENTS

    Component Function
    Blind Spot Monitor Sensor LH and RH

    • Outputs millimeter waves from the blind spot monitor sensor to the blind spot sensor detection area, uses the reflected millimeter waves for detecting the presence of a vehicle, the vehicle-to-vehicle distance, and the relative speed, and then sends this information to the built-in signal processing circuit.

    • The signal processing circuit determines if a vehicle is present, and illuminates or blinks the outer rear view mirror indicator light accordingly.

    • Receives display dimmer signals from the main body ECU and dims the outer rear view mirror indicator light.

    • Illuminates to inform the driver that a vehicle has been detected in the blind spot monitor sensor detection area.

    • Flashes to inform the driver when the turn signal lever is operated if a vehicle has been detected in the blind spot monitor sensor detection area.

    • Both indicator lights flash to inform the driver that a vehicle has been detected in the blind spot detection area while the driver is reversing.
    RCTA Buzzer (Blind Spot Monitor Buzzer) Sounds when a vehicle is detected in the blind spot monitor sensor detection area while the driver is reversing.

    1. The BSM function operates when all of the following conditions are met:


      1. The BSM function is on.

      2. The shift position is other than R.

      3. The vehicle speed is greater than approximately 16 km/h (10 mph).

    2. The BSM function can detect vehicles in its detection areas.


      1. The detection areas formed by the blind spot monitor sensor LH and RH are as shown below.

        B0049RK Detection Area (for Vehicle in Blind Spot) B0049NX Detection Area (for Rapidly Approaching Vehicle from Behind)

        Tech Tips

        If another vehicle that is rapidly approaching the vehicle's blind spot is detected, the notification timing is determined by the relative speed of the approaching vehicle. The notification timing for vehicles rapidly approaching the vehicle's blind spot can be customized. For details, refer to the Repair Manual.

      2. Detection Area (for Vehicle in Blind Spot)


        • When this vehicle is overtaken by another vehicle in an adjacent lane.

    3. According to operation conditions, the BSM function promotes safety confirmation by using the outer rear view mirror indicator light to inform the driver that the system detects vehicles that are in or rapidly approaching the vehicle's blind spot.

    4. The outer rear view mirror indicator light illuminates when a vehicle is in or rapidly approaching the vehicle's blind spot and the turn light switch is not operated. The indicator light flashes when a vehicle is in or rapidly approaching the vehicle's blind spot and the turn light switch is operated.

    5. The RCTA function operates when all of the following conditions are met:


      1. The RCTA function is on.

      2. The shift position is R.

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

      4. The speed of the target vehicle is between approximately 8 km/h (5 mph) and 28 km/h (18 mph).

    6. The RCTA function can detect vehicles in its detection areas.


      1. The system continuously measures the relative speed of an approaching vehicle and its distance. If it is determined that the approaching vehicle will cross the path of this vehicle, the Estimated Crossing Time (ECT) is calculated. When the ECT is 2.5 seconds or less, the system alerts the driver by flashing the outer rear view mirror indicator lights and sounding the RCTA buzzer.

    7. According to operation conditions, the RCTA function promotes safety confirmation by using the outer rear view mirror indicator lights and RCTA buzzer to inform the driver that another vehicle has entered the blind spot monitor sensor alert area of this vehicle.

  3. FUNCTION


    1. Blind Spot Monitor System Operation


      1. The BSM function and RCTA function can be switched on and off by operating the multi-information display with the steering pad switch assembly.

        Tech Tips

        It is not possible to enable the RCTA function only.

      2. An indicator light that can be used to check whether the BSM function and RCTA function are on or off is positioned in the combination meter assembly. When the system is on, the indicator light illuminates, and when the system is off, the indicator light turns off, indicating the operation status.

      3. The brightness of the outer rear view mirror indicator light, volume of the RCTA buzzer and the BSM function detection timing can be set by operating the multi-information display with the steering pad switch assembly.

    2. Customization Function


      1. Settings of some functions can be changed as desired by the user. Refer to the Repair Manual for details.

  4. DIAGNOSIS


    1. The blind spot monitor system is equipped with a diagnosis function that can display warning messages in the multi-information display. For details, refer to the Repair Manual.
