Can someone help me if it's a fuse or something I don't know, I went to Honda they did a diagnosis and it says (multipurpose camera unit variant incomplete u1387-55) they told me that it was possibly the camera I bought an exact one on ebay same model and they showed me that the acc worked in their crv I know that it has to be calibrated, they gave me an estimate that it would come out in 2000 and something, then when I disconnect the camera the Lkass turns on in green and only the acc remains off, I had to change the radar module because it was stolen from me 🤣, but that one works I have a 2017 Honda Crv Ex

@larryr I went to autoglass and Honda and they couldn't calibrate the camera, so I bought one on eBay. I have a DTC that can calibrate the camera but it also tells me the same error and the numbers inside the dashboard don't appear, so now I think it could be a fuse or the wiring (which I hope it isn't because I see everything intact😅)

I'm a little confused about what units you have replaced and why. Have you replaced both the camera and radar? Of course buying anything off of ebay is a real crap shoot. Most units are pulled from wrecks, stolen or known bad units just being sold by a-holes, you have no idea what you are getting.

Know that the radar and camera are matched computer units. A slight difference in the revision numbers can make them incompatible.

Attached is a schematic of the wiring of the camera and radar.

@Traylaw I bought the bumper radar and it detects it and the lkass light goes out!, but when I connect the acc camera, the lkass stops working, then the acc camera is the one that came from the factory with my crv and thinking that was the fault I bought an exact one used by eBay and it also doesn't work for me (sorry for my English I'm using the translator🤣)

edit:I bought the bumper radar because when I bought the vehicle they had stolen it so I don't know the specific model it had
