Caution / Notice / Hint

WARNING: This page is about a different car, the 2023 Toyota GR Corolla and 2023 Toyota Corolla. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
  • When replacing the forward recognition camera, always replace it with a new one. If a forward recognition camera which was installed to another vehicle is used, the information stored in the forward recognition camera will not match the information from the vehicle and a DTC may be stored.
  • When the forward recognition camera has been replaced with a new one, make sure to clear all stored vehicle control history of each system and the forward recognition camera beam axis alignment data.

    HINT: 

    Forward recognition camera beam axis alignment can be performed by using "One Time Recognition", "Driving Adjustment" or "Camera Axis Adjustment Value Write".

    One Time Recognition: Refer to TARGET ADJUSTMENT (ONE TIME RECOGNITION) [09/2022 - 11/2022]

    Driving Adjustment: Refer to DRIVING ADJUSTMENT [09/2022 - 11/2022]

    Camera Axis Adjustment Value Write: Refer to CAMERA AXIS ADJUSTMENT VALUE WRITE [09/2022 - 11/2022]

  • If the forward recognition camera has been replaced with a new one, make sure to perform Software Version Confirmation.

    Refer to SOFTWARE VERSION CONFIRMATION [09/2022 - 11/2022]

  • When replacing the windshield glass of a vehicle equipped with a forward recognition camera, make sure to use a Toyota genuine part. If a non-Toyota genuine part is used, the forward recognition camera may not be able to be installed due to a missing bracket or the forward recognition camera may not operate properly due to a difference in the transmissivity or black ceramic border.
  • Forward recognition camera optical axis may deviate if the vehicle is driven on a banked road, such as a racetrack. This deviation can be corrected by driving the vehicle on a normal road for a while.
  • Forward recognition camera optical axis may deviate when the vehicle is overloaded or the wheel alignment (toe-in) is incorrect. The forward recognition camera optical axis can be corrected by decreasing the load on the vehicle or adjusting the toe-in.
