DTC C1A24: Object Recognition Camera Image cannot be Recognized: 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.

When the object recognition camera sensor cannot process the video, DTC C1A24 is output.
