DTC

C1AA800

Front Recognition Camera Optical Axis Misalignment Malfunction

DESCRIPTION

The forward recognition camera monitors its optical axis status. If it determines that the optical axis alignment has become misaligned, it will store DTC C1AA800.

DTC No.

Front Recognition Camera Optical Axis Misalignment Malfunction

3 seconds or more after the ignition switch is turned to ON, the forward recognition camera detects an optical axis misalignment when the vehicle is being driven at a speed of 5 km/h (4 mph) or more.

  • Windshield glass
  • Vehicle operating conditions
  • Wheel alignment

CAUTION / NOTICE / HINT

NOTICE:

  • When replacing the forward recognition camera, 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 is replaced with a new one or the windshield glass is replaced or removed/installed, make sure to read Before Starting Adjustment, then perform optical axis alignment for the forward recognition camera and clear the vehicle control history for each system.

    HINT:

    Forward recognition camera axis alignment can be performed by using either One Time Recognition, Sequential Recognition or Driving Adjustment.

    Sequential Recognition: Click here 2021 - 2024 MY Camry [10/2020 -        ]; CRUISE CONTROL: FRONT CAMERA: TARGET ADJUSTMENT(SEQUENTIAL RECOGNITION)

    Driving Adjustment: Click here 2021 - 2024 MY Camry [10/2020 -        ]; CRUISE CONTROL: FRONT CAMERA: DRIVING ADJUSTMENT

  • 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

Click here 2021 - 2024 MY Camry [10/2020 -        ]; CRUISE CONTROL: 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.

CHECK WHEEL ALIGNMENT (TOE)

  • for Front Wheel Alignment: Click here 2021 - 2024 MY Camry [10/2020 -        ]; ALIGNMENT / HANDLING DIAGNOSIS: FRONT WHEEL ALIGNMENT: ADJUSTMENT
