Back-Up Camera, Trunk Floor Wiring Harness

[Buddy]

I am a Retired Automotive Engineer and owner of a Fully Loaded 2015 Hyundai Genesis. With only 38,500 miles on my Genesis I started having intermittent problems with my "back-up camera". I done as the forum suggested opening and closing the trunk. It corrected the "back-up camera" for a while but, eventually the "back-up camera" failed completely. Only grid lines were present. I decided to go to the process of elimination and replaced the camera. I replaced the camera and still no fix, just the same grid lines. I investigated further and found the Hyundai Technical Service Bulletin on certain 2015-2016 Genesis (DH) Trunk Floor Wiring Harness Inspection And Repair. I found four wires that were completely broken (see attached photos). I repaired the wires after following the instructions in the Technical Service Bulletin. My "back-up camera" is functioning like new now. I probably save myself a couple of thousand dollars vs a dealership. The point I like to make is the "back-up camera" issue is clearly a "manufacturing flaws". This should had been address via recall. Hyundai decided it would be more cost effective to loose would be buyers than to initiate a recall. The winner in all of the "back-up camera" issues is the dealership and clearly not the consumer.

I would argue that is is a design flaw, rather than a manufacturing flaw.

The 2015 Genesis does indeed has a TSB about repairing the damaged trunk wires(which affects the taillights and reverse camera) and relocating the wiring harness to an area with less bending of the wires. I repaired my own wires and relocated my harness to the new location.

My Genesis broken wire harness and old metal bracket location.

The wires repaired with metal butt connectors and shrink wrap. I used aluminum foil to protect the other wires from the heat gun.

The harness repaired and the old metal bracket for the wiring harness removed and the wiring harness moved to recommended location.

Yeah, I had this issue and the dealership ran a line from the head unit back to the trunk, rather than splicing the line. Now the camera has gone out again. I have tried to repair it and followed the instructions in the TSB, but no luck.
Hyundai clearly DNGAF about this issue.

I stand corrected, you're right. It is more of a design flaw rather than a manufacturing flaw. I also think that "auto back-up cameras" should be part of the National Auto Safety. Thanks for reply

Actually it more of a planning/testing issue in terms of were to route and support the wires. The old wiring harness bracket location just allows too much tension on the wires when the trunk open and closes; which breaks the wires over time. The overall design of the wiring harness is fine; only one support bracket was mounted in a bad location for real world use.

The new wire harness mounting location allows the wires to move more freely with less tension when the trunk open and closes. Over-sights or poor mounting choices happen in many makes and is usually corrected in later models.

The fix on the Genesis is fairly easy; unless the reverse camera wire is broken. Optical cables are not as easy to splice like standard wires. I believe that the Genesis reverse camera cable is maybe optical. Hopefully, the reverse camera wire cable is just plain wires under a gray sleeve.

Unless they used a new complete camera module wiring harness that feeds all the way back to the radio; the new cable was spliced into the old camera module wiring. The cause of your camera failure is probably due to the spliced connection failing.

The reverse camera wiring is co-ax. This is more difficult to splice to be sure, but it can it done. It is not optical.
I design wiring harnesses among other things. Mounting locations is definitely a part of the design for us. It's an even bigger part for us for cables that have to move. (And yes, the more we do, the more we learn.)

Coaxial cable...Well much better than trying to splice fiber optic cable. Luckily my harness only had damage to the plain wires that powered the taillights. Thanks for the information.

We both may be incorrect about the reverse camera wiring. The reverse camera cable is labeled AVSS BS; which means a couple wires(probably camera signal and power wires) shielded covered in a vinyl coating. Not a coaxial cable with a single solid core wire and shielding nor a fiber optic cable. However, it is more like a coaxial cable than a fiber optic cable. The wire label is easily seen in the pic located in post #1.

Yes, you are right. I should have said shielded cable.

 

[carguy75]

Well, you was still closer to the actually cable type than I was. Plus, repairing a broken AVSS-BS cable is the basically same as repairing(splicing) a broken coaxial cable.

My Coaxial cable was severed. It wasn't that hard to splice back together but I didn't realize it was just shielding . I almost just threw some tape on the insulation. I'm glad I dug around little bit. I cant get the top view to work though but I can deal with that.

I also have the same issue I went to Hyundai and they told me it’s the backup camera issue and need a new one then they replaced it but it was not working then the technician told it’s the worn harness and need 3800 + to fix it I asked them why did I pay 150$ + tax to check the problem he told they will check only with obd I told him I can buy an obd in that price …it’s the manufacture defect how could Hyundai Genesis could cheat their defect by hiding it and not recalling and fix the issue..
