Reversing camera Sync 3

Right

ive spent days scouring the internet and think this may work

so inside an rca cable is 3 wires. 

Red 12v 

black video -

yellow video +

the grey connector has 6 pins

pin 1 is white 12v

pin 4 is blue video +

pin 5 is green video -

so if you join the black rca wire to pin 5 and yellow rca wire to to pin 4 then it should give you video. Join the red 12v wire to white pin 1 and then join the other side to the camera power cable and this should power the camera when in reverse. Earth the camera from inside the tailgate and fingers crossed this works. 

Hello everybody,

My car: 2015 Ford Focus, 1.5 TDCi, wagon.
The gray connector with 6 pins in the trunk is present.
I bought a reverse camera from Aliexpress, specifically the one from the link, model AHD1080P-175Deg.

I connected it according to the instructions above:
-The yellow wire from the RCA connector to the blue wire on the 6-pin connector (theoretically represents video+)
-The black wire from the RCA connector to the green wire on the 6-pin connector (theoretically represents video-) Two more wires were coming out of the camera:

Besides the RCA connector was another cable :
-One black/red (which generally represents ground) to the ground pin of the connector that goes into the reverse light on the tailgate
-One red (which generally represents power, in this case 12V) to the pin that receives 12V from the connector that goes into the reverse light on the tailgate.

I programmed the APIM with Forscan: I tried both the American and European camera variants.
I can't get a signal from the camera and I receive the message from the attached picture on the SYNC2 of the car, about 10 seconds after I put the car in reverse.
For the sake of trying, I also connected the red wire coming out of the RCA video connector (the trigger wire) to the white wire of the gray 6-pin connector, which receives 12V when you put it in reverse.
No variant seems to work for me and it's already extremely frustrating.
I also tried with the cut wire (the one that reduces the quality from 1080p to 720P, AHD to CVBS). Still no improvement.
Can you help me with information? I can't find anywhere a complete tutorial written from start to finish or a complete video with all the steps.

Thank you!

That is the wrong camera to be connected up using the grey plug in the car.

If you want to use the grey plug fitted in the car then you need a OEM camera. If you want to use the Aliexpress aftermarket camera then you will need to run a signal cable all the way from the camera through to the APIM and use an adapter plug.

Thank you. It works with an APIM + RCA adapter.
For some reason I am having a "background" issue in the top-left corner, stretching up to the top-left side of the screen. Please see video and/or the attached picture.
Any ideas ?
Thank you

Too many! That is the problem. This is purely signal quality problem, it might be connection issue like to high resistance, low signal level, disturbances, ground connection (wrong place, wrong side), signal shielding, poor cables quality, power quality, etc. etc.

The only way to fix it, is to try every possible case. Firstly, I'd try to connect camera with short cables close to APIM.

OEM camera or china?

Thank you. I'll just ignore it as long as it works. When/if it dies and needs a replacement, I will try "debugging" the issue.
Regarding the camera it is China, of course 😄 
Have a great one!

Hey everyone, looong time since I've posted around these parts and apologies for resurrecting an old thread but... I've just installed a reverse camera to my 2015 mk3.5, grey plug present in the boot, four parking sensors on the rear. So I bought the proper ford loom along with a second hand boot handle with camera, everything is fitted and I've today activated it with Forscan. I get the picture up on the screen and it's working basically as it should however the zoom feature doesn't appear to work and I don't get the white lines that move with the steering wheel. I can live with that but it's logged a code in the APIM module "U2101 Control Module Configuration Incompatible". Has anyone had this before and is there another setting I need to change to clear this? I've read early on in this thread about running a service on Forscan but I didn't see anything relevant under the spanner tab.

Any help or advice gratefully received, thank you.😇

See a similar thread for MK4, just a few days ago I posted some details about the problem you have:

Thank you, I haven't changed anything in the BdyCM so that sounds like my next place to look.👍 Forscan is on the computer at work so I will have a look tomorrow on my coffee break and report back.

I had a look at that today, went into the BCMii (main) and by going into one of the engineering sections I found park assist camera, it was the only option I could find that related to it. I changed it to with park assist camera but I couldn't run the New Module Calibration service. It said switch off ignition then switch back on but at this point it said service interrupted and didn't do anything. This then put a code into the IPC saying that it had lost communication with the rear camera.🤷 So I've put it back to how it was and I've just got one code now and a camera with no lines or zoom function.

I but I couldn't run the New Module Calibration service.

Do you have OEM camera? LIN bus wire is connected between BCM (also known as BdyCM) and the camera?

In the other thread, which link I have attached, I mention about modifying BCM configuration in the AsBuild section, not engineering one. There is a whole byte, which tells BCM how to use LIN line. Once this byte is set correctly (6F), you can ran the "New Module Calibration" procedure. Somehow, factory values are not so bad, that you fail in this procedure, just no "wide view". So, It might be, that in your case you have wiring problem or other misconfiguration.

In the AsBuild configuration, there is a button to store the whole module configuration. If you can send me this file for BCM & APIM, I'll check if it has all correctly set.

I'm not actually 100% sure, I bought it with a genuine handle and wiring loom but it could be a non genuine camera, I need to change the handle part so when I do that I'll check the camera.

I don't think mine is capable of the wide view or split view it only mentioned multiple cameras. I'm not concerned about that function.

I also looked in the AsBuild section but there wasn't a 726-15-02 line so I didn't look any further. I'll have another look and see if I can send you those files.

Thank you again for your help.

I've thought about this some more and I've decided I'm going to leave it as it is. It's doing what I need it to do which is allow me to reverse up to a trailer hitch easily. I'm nervous about doing these changes so I feel more comfortable just leaving it as it is. Thank you once again for your help and advice.👍

Hi guys, I'm a little late on this thread.

I own a mk3 "pre face lift" Focus SW from september 2014, originaly fitted with Sync1, front/rear sensors and "parallel park assist".

I've installed an aftermarket camera (set to "with park assist camera" in the BCM using Focccus), everything worked OK.

 

Few weeks ago, I upgraded to Sync3 system, and after few tries and fails, managed to activate the rear camera. But, the image is completely grey (as if the camera was muddy/dirty, but the camera is clean).

So what's the issue? something wrong in the programing? (should I set to "without camera" in the BCM with Focccus - in the same way some Sync1 options needed to be set to NO/Without))

Eveything seems to be correctly plugged (as I didn't changed the wiring ("red+" and "black ground"), except the RCA connected to my Sync3 harness)

See the image...

Any help is welcome🙂
