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 transmits 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 accordingly.

    • Dims the outer rear view mirror indicator light on the outer rear view mirror assembly.

    • Transmits the indicator light signal to the outer rear view mirror assembly.

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

    • Flashes to inform the driver when the turn signal lever is operated if a vehicle has been detected in the blind spot 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.
    Combination Meter Assembly Master Warning Light When a malfunction is detected in the blind spot monitor sensors or the blind spot monitor sensors determine that control is not possible, the master warning light illuminates and a message is displayed on the multi-information display to warn the driver.

    ECM Transmits the reverse signal to the blind spot monitor sensor LH and RH.
    Brake Actuator Assembly Skid Control ECU Transmits the vehicle speed signal to the blind spot monitor sensor LH and RH.
    Main Body ECU (Multiplex Network Body ECU) Transmits the destination signal, illumination signal and dimmer signal to the blind spot monitor sensor LH and RH.
    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.

  2. SYSTEM CONTROL


    1. The blind spot monitor function operates when both of the following conditions are met:


      1. The blind spot monitor function is on.

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

      3. The shift lever is in a position other than R.

    2. The blind spot monitor 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.

        B0082ZQC05
        *a Approximately 3.5 m (11.5 ft) *b 3.0 m (9.8 ft)
        *c 1.0 m (3.3 ft) - -
        B0082SQ Detection Area - -

      2. When this vehicle is overtaken by another vehicle in the adjacent lane.

        B0082YJC03
        *a This Vehicle - -
        B0082XT Vehicle Speed (Fast) B0082R6 Vehicle Speed (Slow)
        B0082SQ Detection Area - -

      3. When another vehicle enters the detection area of this vehicle due to a lane change.

        B008320C07
        *a Other vehicle enters the detection area during lane change (merge in) (Type 1). *b Other vehicle enters the detection area during lane change (merge in) (Type 2).
        *c This Vehicle - -
        B0082XT Motion direction of this vehicle B0082R6 Motion direction of other vehicle
        B00831B Detection Area - -

    3. According to operation conditions, the blind spot monitor function promotes safety confirmation by using the outer rear view mirror indicator light to inform the driver that another vehicle has entered the blind spot monitor sensor detection area of this vehicle.

    4. The outer rear view mirror indicator light informs the driver that a vehicle is present in the blind spot detection area by illuminating when the turn light switch is not operated, and by flashing when a vehicle is present 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 lever is in R.

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

      4. Target vehicle's speed 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 blind spot monitor buzzer.

        B0082O2C01
        *a This Vehicle *b Target Vehicle (Approximately 8 km/h (5 mph))
        *c Target Vehicle (Approximately 28 km/h (18 mph)) *d Approximately 5.5 m (18.0 ft.)
        *e Approximately 20 m (66 ft.) *f Target Detection Line
        B0082SQ Alert Area - -

      2. Normal Parking

        B0082TYC01
        *a This Vehicle *b Target Vehicle
        B0082SQ Alert Area - -

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

    8. When this vehicle is reversing, if a vehicle enters the detection area of the blind sport monitor sensors and it is determined the vehicle will cross the path of this vehicle, the system alerts the driver by flashing the outer rear view mirror indicator lights and sounding the blind spot monitor buzzer.

  3. FUNCTION


    1. Blind Spot Monitor System On/Off Setting


      1. The blind spot monitor function and RCTA function can be turned on/off separately via the multi-information display.

      2. A blind spot monitor function indicator and RCTA function indicator are located on the combination meter assembly to indicate the on/off status. The indicator illuminates when the function is on and does not illuminate when the function is off.

    2. Blind Spot Monitor System Setting


      1. The brightness of the door mirror indicator can be changed between 2 levels and the RCTA buzzer volume can be changed between 3 levels via the blind spot monitor setting screen displayed on the multi-information display.

  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.
