Back-up Camera problems

Remember, the BRZ is a low selling vehicle and the number of your particular Kenwood head would make only a couple of vehicles they prepared the loom for. You might even be the only one for your Kenwood model.

That was the first thing I did. The second thing I did was post here to see about troubleshooting tips. Any help you can provide with troubleshooting would be greatly appreciated.

Since you spoke to them, what did they say about the 12v to 6v adapter? The other issue would be a manufacturing defect on the loom with a poor connection. There are lots of places where there could be a problem. You would need to take out the loom and use a continuity tester to test the connections. Sometimes pins inside the connectors can be pushed loose. If you are pushing 12v to a 6v device, there can also be damage to the device depending on the circuitry.

They said the camera should work and sent another cable in case the first one was bad. I don't think you were following my previous posts about what I'm looking for and what's been offered. And I don't think you are familiar with this setup from Carbon. We've eliminated the concerns about the fuse. I'm not sure I am getting back signal so there might be problem somewhere else besides the 12/6volt issue you are locked in on. Thanks for the help.

Just trying to check all of the boxes. The camera signal is analog, so one cable carries the picture. Since the camera is only turned on in reverse, it needs to be turned on by either the head unit or hooked to the back-up lights. I believe the OEM head unit has an out that is sent to the camera to turn it on. I don't know how it is connected in the BRZ. So I would first check if your back-up lights work and that the fuse for that circuit is still good. That's easy. My guess is that it is probably all right, but it doesn't hurt to check.

My concern with the 12/6 volt issue is that if it first worked, and then didn't, it would seem that something blew in the circuit potentially due to the voltage difference. It could be the fuse, which you checked, or it could be in the camera circuits which are located in the camera. That is not an amperage issue which is what the fuse checks. If it did first work, and then you didn't touch it, and then it didn't work, chances are the wiring is correct.

Since you are so sure that all of the wiring is correct, and that there isn't a voltage issue or a wire shorting out on the back of the unit, I'm out of ideas. Sorry nothing helped here. I've done a number of installs, and this has never happened to me as I'm pretty careful to check all of the components as I install. That said, I've done no installs on the BRZ so if there is anything special here, I wouldn't know.

Good luck... I'm outta here....

I have a DDX917WS and also ordered the pre-made harness from Carbon.

Can confirm my camera NEVER worked with their harness. A local shop I took it to told me that it didn't include the 12v/6v drop (Carbon assured me this was fine and wasn't the problem), and that it wasn't wired correctly to take a camera signal. Unfortunately I don't know how they modified the harness or if they had additional harnesses... I just wanted it fixed and they delivered.

A couple other people here have used the carbon harness mostly without issue (amp trigger was not wired on early revisions) with USA cars.

I do have a Canadian car so maybe there are some minor wiring differences?

If I had to do it again I would either learn to make my own harness or let a local shop build one for me. Carbon doesn't have bad customer service but there is no way for them to effectively troubleshoot this overseas. Probably why they don't ship these units over here anymore.

What exactly did Carbon Change?

Well I'm talking to them right now trying to get a harness shipped to the states and I know for a fact they said they fixed the issue with the no bass coming out of some of the speakers.

"We have since fixed the issue with the Sub it was a power wire for the factory amp the harness is now good. "

Is what I was told when they asked me about it. Whether or not it has the 12 >6v fix I'm not sure. I'm hopeful I can convince them to send me one, and if necessary adding that fix to it shouldn't be too tough.

Yeah it is my understanding that the amp trigger is the ONLY thing they have ever changed in that harness.

I purchased in November 2017 and it didn't have the 12v/6v stepdown, that was something my local shop provided. On Carbon's website the harness still looks exactly like what I bought, so I don't think it has changed.

Hey guys! Sorry to resurrect an old thread.

I too have an '18 Limited BRZ and purchased a CCS loom harness to hook up with my Kenwood DDX919WS.

I've got everything finally working after troubleshooting the USB ports and camera issues.

I have both cameras working (both front and rear since the HU has outputs for both) but I'm getting a scrolling static image - the front camera displays a ghosting image of the rear and the rear display a ghosting image of the front.

I've checked all my connections and even tried a couple of different grounding points.

Have you guys fixed your issues? I'm wondering if I need a 12v relay/filter/capacitor to attempt to eliminate the static issue?
