CAUTION / NOTICE / HINT

NOTICE:

  • 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".

  • 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.

PROCEDURE

1.

CHECK FORWARD RECOGNITION CAMERA INSTALLATION

HINT:

Click here 2023 - 2025 MY Corolla Corolla Hatchback Corolla HV GR Corolla [11/2022 -        ]; ADVANCED DRIVER ASSISTANCE SYSTEM: FRONT CAMERA: INSTALLATION

HINT:

If there is deformation or deviation in the forward recognition camera installation bracket, replace the windshield glass.

OK:

No deformation or deviation in forward recognition camera installation bracket.

NG

GO TO STEP 11

OK

2.

CHECK VEHICLE OPERATING CONDITION

HINT:

Check if a condition which caused the forward recognition camera optical axis to become temporarily misaligned existed, such as if the vehicle was overloaded, towed or modified.

OK:

Vehicle was not overloaded, towed or modified.

NG

GO TO STEP 9

OK

3.
