CRUISE CONTROL  FRONT CAMERA SYSTEM  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. Detection Item DTC Detection Condition Trouble Area
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 (4 mph) or more, after 3 seconds have elapsed since the ignition switch was turned to ON.

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 (RoB) for each system.

HINT:

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

One Time Recognition: Click hereEngine / Hybrid System>CRUISE CONTROL>FRONT CAMERA>TARGET ADJUSTMENT(ONE TIME RECOGNITION)

Sequential Recognition: Click hereEngine / Hybrid System>CRUISE CONTROL>FRONT CAMERA>TARGET ADJUSTMENT(SEQUENTIAL RECOGNITION)

Driving Adjustment: Click hereEngine / Hybrid System>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
