PRE-CRASH SAFETY SYSTEM UTILITY

Note


  • If "Recognition Camera/Target Position Memory" and "Recognition Camera Axis Adjust" are not performed, all of the systems using the pre-crash safety city sensor may be affected.

  • When replacing the pre-crash safety city sensor with a new one, or performing removal, installation or replacement of the windshield glass, always perform "Recognition Camera/Target Position Memory" and "Beam Axis Learning".

    Perform adjustment with either "ONE TIME RECOGNITION" or "SEQUENTIAL RECOGNITION".


  • When replacing the windshield glass of a vehicle equipped with a pre-crash safety city sensor, make sure to use a Toyota genuine part. If a non-Toyota genuine part is used, the pre-crash safety city sensor may not be able to be installed due to a missing bracket or the pre-crash safety system may not operate properly due to a difference in the transmissivity or black ceramic border.

Tech Tips

The pre-crash safety city sensor recognizes the white lines in relation to the vehicle on the basis of coordinates derived from the traveling direction of the vehicle. These coordinates differ for each vehicle depending on the tolerance and installation position of the pre-crash safety city sensor to the vehicle. Therefore, pre-crash safety city sensor beam axis adjustment must be performed individually for each vehicle.


  1. RECOGNITION CAMERA/TARGET POSITION MEMORY


    1. Before performing "Recognition Camera Axis Adjust", store the recognition camera position information, target position information and vehicle information in the pre-crash safety city sensor.

      Tech Tips

      For pre-crash safety city sensor adjustment procedures.

      Perform adjustment with either "ONE TIME RECOGNITION" or "SEQUENTIAL RECOGNITION".


  2. BEAM AXIS LEARNING


    1. After storing the "Recognition Camera/Target Position Memory", further calibrate the stored data.

      Tech Tips


      • Since there is an error in the internal data derived from the stored recognition camera position (horizontal and vertical coordinates, etc.), calibrating the internal data captured in the recognition camera improves the recognition sensitivity of the recognition camera.

      • For pre-crash safety city sensor adjustment procedures.

        Perform adjustment with either "ONE TIME RECOGNITION" or "SEQUENTIAL RECOGNITION".


  3. ENTER CONTROL MODE


    1. When reproducing the problem symptom of the pre-crash safety system function, do not operate the pre-crash brake and only operate the warning (operations and buzzer sounding).

      Tech Tips

      When reproducing the problem symptom of the pre-crash safety system function, actually operating the pre-crash brake would be dangerous. To avoid this, when triggering operation of the pre-crash safety system function, do not operate the pre-crash brake and only operate the warning.

  4. PCS IMAGE RECORD SETTING


    1. Set the PCS image storage to valid or invalid.

      Tech Tips


      • When the pre-crash brake operates, image data is stored in the pre-crash safety city sensor.

      • The stored image information cannot be viewed.

  5. PCS IMAGE INFORMATION CLEAR


    1. Clear the PCS image information stored in the pre-crash safety city sensor.

  6. HISTORY CLEAR


    1. When the history data status is "ON", clear the history.
