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. |

C1AA800 |
Front Recognition Camera Optical Axis Misalignment Malfunction |
When the forward recognition camera detects an optical axis misalignment when the vehicle is being driven at a speed of 5 km/h (3 mph) or more, after 2 seconds have elapsed since the ignition switch was turned to ON. |
|
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 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.

- 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 |
(a) Check the installation condition of the forward recognition camera.
Click here
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.

|
|
|
2. |
CHECK VEHICLE OPERATING CONDITION |
(a) Check the operating conditions of the vehicle.
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.
