ADVANCED DRIVER ASSISTANCE SYSTEM FRONT CAMERA SYSTEM(Production Date from 2023/04) 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.

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".; One Time Recognition: Click hereADAS / AD>ADVANCED DRIVER ASSISTANCE SYSTEM>FRONT CAMERA (Production Date from 2023/04)>TARGET ADJUSTMENT(ONE TIME RECOGNITION)202201,999999,_95,_112293,_0580211,RM1000000028VIV,; Driving Adjustment: Click hereADAS / AD>ADVANCED DRIVER ASSISTANCE SYSTEM>FRONT CAMERA (Production Date from 2023/04)>DRIVING ADJUSTMENT202201,999999,_95,_112293,_0580211,RM1000000028VIX,; Camera Axis Adjustment Value Write: Click hereADAS / AD>ADVANCED DRIVER ASSISTANCE SYSTEM>FRONT CAMERA (Production Date from 2023/04)>CAMERA AXIS ADJUSTMENT VALUE WRITE202201,999999,_95,_112293,_0580211,RM1000000028VIY,

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

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
