It''s all related. The "LKAS has a problem" message is on as well pre-collision warning system and am sure BLIS is also off. I scanned what am Abe to communicate with ad got this. I don't even see where the side cameras for the BLIS are on the mirrors but I see on the inside of the door that it does have it.

What to check next

Diagnostic guidance. Suggested checks and possible repairs are separate from the owner's reported results.

Have the replacement camera's compatibility and the manufacturer's required setup, aiming or calibration steps verified for the actual vehicle. Obtain a post-repair scan with equipment that can communicate with the affected systems. The warning lights going out is the reported improvement. The discussion does not document calibration or functional verification of every driver-assistance feature.

Guidance references and applicability

2CarPros: Original discussion 1712405 https://2carpros.com/questions/lkas-collision-sensor-bsi Source for the owner's reported history and outcome. Contributor suggestions are not independently confirmed diagnoses. No attachment content was verified. I-CAR: OEM calibration requirements https://rts.i-car.com/oem-calibration-requirements-search.html Explains the need to identify vehicle-specific post-repair calibration and aiming requirements. Consult current vehicle-maker information; extinguished warning lights are not a calibration record.

From your screenshots, the big one is:

U3000-49 - Multipurpose Camera Unit / Millimeter Wave Radar Internal Electronic Failure

No, the BSI sensors are not in the mirrors. They are radar units behind the rear bumper corners. And based on your codes, I would start by diagnosing the front radar/camera system. I would clear the codes, then turn the car back on and without driving it run the codes again. That way we can see which comes come sus first.

I see. Where is the Ian camera behind the rear view mirror? This is a one owner vehicle with only minor accident that happened in 2016 when it was new, on back left, but I doubt it has been left like this since then. I will look under rear bumper hopefully they are visible.I also read couple of places that it could be related to a weak battery. Car starts but I feel a minor struggle so I will charge it and re run the car and see what I get. Also read somewhere that it could be transmission related

I don't think it is either the battery or the transmission, did you clear the codes and then turn the car on and rerun the codes? This will tell us which code is most prevalent.

I cleared all but I cannot communicate with all systems as they are separate, scanner says not supported, but with the main camera I have the code even after I clear all; u3000-49

Yep, so the "Multipurpose Camera Unit" is up by the rear view mirror, I would check that out and then get a used one from ebay and try that, these camara are subject to heat which makes them go out. Then clear the codes and let me know.

Discussion summary

LKAS collision sensor BSI?

The owner reported lane-keeping and collision-system warnings, suspected a blind-spot-system issue and had limited scanner access. The owner explicitly reported that U3000-49 returned for the main camera after clearing. Following the suggestion to replace the camera near the rearview mirror, the owner installed a used unit and reported that all warning lights went out.

Reported outcome: The owner reported that all warning lights went out after installing the used camera.

The original scanner screenshots were not available in this export, and the owner's scanner could not access every system. No calibration report or complete post-repair scan was supplied. Heat damage and separate blind-spot-sensor failure were not established.
