C1A25
PRE-COLLISION: PRE-COLLISION SYSTEM: C1A22,C1A23,C1A25: Object Recognition Camera Incorrect Axial Gap
C1A25 - Object Recognition Camera Recognizing Distance Discrepancy
DESCRIPTION
The driving support ECU uses the front millimeter wave radar sensor, driver monitor camera and object recognition camera to detect obstacles in front of and behind the vehicle, and detect the direction that the driver's head is facing. Based on this information, the driving support ECU sends pre-collision control operation signals.
If the driving support ECU determines that the object recognition camera's axis is deviated, DTC C1A22 is output. Also, after installing the object recognition camera : 1) if the camera beam axis adjustment is not performed, DTC C1A23 is output; and 2) if the left and right camera's obstacle distance information is different, DTC C1A25 is output.
