DTC C1A22 Object Recognition Camera Incorrect Axial Gap; DTC C1A23 Object Recognition Camera Initialization Incomplete; DTC 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 sensor's axis is deviated, DTC C1A22 is output. Also, after installing the object recognition camera sensor: 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.
DTC DETECTION CONDITION CHART
| DTC Code | DTC Detection Condition | Trouble Area |
|---|---|---|
| C1A22 | While engine switch is on (IG), driving support ECU detects object recognition camera beam axis deviation for 1 sec. |
|
| C1A23 | While vehicle is driven at 5 km/h (3 mph), driving support ECU detects that object recognition camera's adjustment has not been completed for 1 sec. |
|
| C1A25 | While engine switch is on (IG), driving support ECU detects that left and right camera's distance information is different for 1 sec. |
