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

      • 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.
      Blind Spot Monitor Main Switch (Warning Canceling Switch Assembly) Pressing the blind spot monitor main switch turns the blind spot monitor system on or off.

      Outer Rear View Mirror Assembly


      • Outer Rear View Mirror Indicator Light

      • Illuminates when a vehicle is detected in the detection area.

      • Blinks when the turn signal switch is operated while a vehicle is detected in the detection area.

      Headlight Dimmer Switch Assembly


      • Turn Signal Switch

      		 Transmits the turn signal switch signal to the blind spot monitor sensors LH and RH.
      Combination Meter Assembly Multi-information Display*1 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.
      Master Warning Light*1 Illuminates at the same time as when the multi-information display is turned on.
      Blind Spot Monitor Indicator*2 Illuminates the blind spot monitor indicator when the blind spot monitor system malfunctions and when the system cannot be used temporarily to inform the driver.
      Steering 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.
      Main Body ECU (Multiplex Network Body ECU)

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

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

      • Transmits the dimmer signal to the blind spot monitor sensors LH and RH.
      ECM Transmits the reverse signal to the blind spot monitor sensors LH and RH.

  2. SYSTEM CONTROL


    1. Operating Condition


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


        • The blind spot monitor main switch is on.

        • The vehicle speed is greater than approximately 40 km/h (25 mph).

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


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

          A00YYPKC01
          *a Approximately 3.0 m (9.84 ft.) *b Approximately 1.0 m (3.28 ft.)
          *c Approximately 0.5 m (1.64 ft.) - -
          A00YYCW Detection Area - -

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

          A00YYDTC01
          *a Other Vehicle *b This Vehicle
          A00YYR0 Vehicle Speed (Fast) A00YYDY Vehicle Speed (Slow)
          A00YYCW Detection Area - -

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

          A00YY0GC01
          *a Other Vehicle *b This Vehicle
          *c Other vehicle enters the detection area during lane change (merge in) (Type 1). *d Other vehicle enters the detection area during lane change (merge in) (Type 2).
          A00YYR0 Motion Direction of Other Vehicle A00YYDY Motion Direction of This Vehicle
          A00YYCW Detection Area - -

  3. FUNCTION


    1. According to operation conditions, the blind spot monitor system 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 signal switch is not operated, and by flashing when a vehicle is present and the turn signal switch is operated.

  4. DIAGNOSIS


    1. The blind spot monitor system is equipped with a diagnosis function that can display warning messages on the multi-information display*1 or illuminate the blind spot monitor indicator*2. For details, refer to the Repair Manual.
