BLIND SPOT MONITOR SYSTEM


  1. FUNCTION OF MAIN COMPONENTS


    1. The blind spot monitor system has the following functions:

      Function Outline
      Blind Spot Monitor Sensor

      • Output 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 light accordingly.

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

      Outer Rear View Mirror Assembly


      • Outer Rear View Mirror Indicator Light

      • Illuminates when a vehicle is detected in the detection area (blind spot monitor function).

      • Blinks when the turn signal switch is operated while a vehicle is detected in the detection area (blind spot monitor function).

      • Blinks when another vehicle is detected in the alert area while the vehicle is backing up (rear cross traffic alert function).
      Combination Meter Assembly Blind Spot Monitor Indicator Illuminates when the blind spot monitor system is turned on and goes out when the system is turned off in order to inform the driver of the system status.
      Multi-information Display

      • Displays the setting screen to turn the blind spot monitor system on or off.

      • Displays "CHECK BSM SYSTEM" when the blind spot monitor system malfunctions and "BSM NOT AVAILABLE" when the system cannot be used temporarily to inform the driver.

      Headlight Dimmer Switch Assembly


      • Turn Signal Switch

      		 Transmits the turn signal switch signal to the blind spot monitor sensors LH and RH.
      Steering Angle Sensor Transmits the steering angle signal to the blind spot monitor sensors LH and RH.
      Skid Control ECU Transmits the vehicle speed signal to the blind spot monitor sensors LH and RH.
      Speed Sensor Transmits the vehicle speed signal to the skid control ECU.
      Main Body ECU (Driver Side Junction Block Assembly)

      • Transmits the destination signal to the blind spot monitor sensor LH and RH.

      • Transmits the illumination signal to the blind spot monitor sensor LH and RH.

      • Sends a blind spot monitor system on or off signal to the blind spot monitor sensor LH and RH.
      ECM Transmits the reverse signal to the blind spot monitor sensors LH and RH.
      Multi-information Switch The blind spot monitor system can be turned on or off by operating this switch.
      Driving Support Switch Control ECU Receives a signal from the multi-information switch, and sends a blind spot monitor system on signal or off signal to the main body ECU.
      Rear Cross Traffic Alert Buzzer (Blind Spot Monitor Buzzer)* Sounds when a vehicle is detected in the alert area while backing up.

  2. SYSTEM CONTROL


    1. Operating Condition (Blind Spot Monitor Function)


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


        • The blind spot monitor system is on.

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

      2. The blind spot monitor function can detect vehicles in its detection areas.


        • The detection areas formed by the blind spot monitor sensors LH and RH are as shown below:

          A019QNDC01
          *a 3.5 m (11.5 ft.) *b 3.0 m (9.8 ft.)
          *c 1.0 m (3.3 ft.) *d 0.5 m (1.6 ft.)
          A019QBW Detection Area - -

        • The driver's vehicle is overtaken by another vehicle in the adjacent lane.

          A019QR2C01
          *a This Vehicle - -
          A0009RQ Vehicle Speed (Fast) A01N5I9 Vehicle Speed (Slow)
          A019QBW Detection Area - -

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

          A019R3YC01
          *a This Vehicle *b Other vehicle enters the detection area during lane change (merge in) (Type 1).
          *c Other vehicle enters the detection area during lane change (merge in) (Type 2). - -
          A0009RQ Motion Direction of Other Vehicle A01N5I9 Motion Direction of This Vehicle
          A019QBW Detection Area - -

    2. Operating Condition (Rear Cross Traffic Alert Function)


      1. The rear cross traffic alert function can detect vehicles in its detection areas.


        • The system continuously measures the relative speed of an approaching vehicle and its distance. If it is determined that the approaching vehicle will cross in 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 rear cross traffic alert buzzer.

          A019QGNC01
          *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 (65.6 ft.) *f Target Detection Line
          A019QBW Alert Area - -

        • Normal Parking

          A019QFXC01
          *a This Vehicle *b Target Vehicle
          A019QBW Alert Area - -

        • Angle Parking

          A019QG5C01
          *a This Vehicle *b Target Vehicle
          *c Approximately 55 to 140 degree - -
          A019QBW Alert Area - -

  3. FUNCTION


    1. Blind Spot Monitor Function


      1. 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.

      2. 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.

    2. Rear Cross Traffic Alert Function


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

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

  4. DIAGNOSIS


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