Hey there,
Would be grateful and/or pay if anyone can help me solve this issue. Thank you in advance!
I purchased a Sync 3 Upgrade from a US based online vendor who promised all kinds of tech support, but alas, now they will not respond. Anyway, I upgraded a 2015 Ford Focus SE with the 4" small screen and button style radio to the 8" screen and obviously added the Sync 3 APIM from this vendor. After some hiccups (3 months worth with them), finally the system seems to work normally. Except for the reverse camera (which does work). The issue seems to be that the APIM is not seeing that the car is in reverse or is coded incorrectly. The instrument cluster knows the car is in reverse and the reverse sensors act normally. The reverse camera does work through the unit if you scroll over to settings on the Sync 3 screen and manually ask it to come on. It will then stay on until you turn it off. It will not come on automatically when the car is shifted to reverse (it is a 5 speed car and a very rare configuration, so I’m wondering if that has anything to do with it?). There are zero active codes in the car and everything else seems to work normally. I sent pictures of the APIM configuration from Forscan and the coding to the vendor but alas, they are no longer responding. Any help would be greatly appreciated!
Thank you,
Chris
I’m assuming you have Forscan, right?.
If that’s so, can you share the APIM’s asbuilt values seen through Froscan?.
Also, have you checked our https://cyanlabs.net/asbuilt-db/sync3-apim/ for any relevant camera configuration that may apply? (make sure to save your current asbuilt as backup)
Hey SaNdMaN,
Thank you for your reply. Here is what is showing in the car’s APIM now. Is this what you are referencing? Would the “as built” data even be valid since I have added the 8” screen, new APIM, and Sync 3? I’ll send whatever I can or can figure out!
Thank you,
Chris
I’m not that knowledgeable about these things, I will look into it later, but I wanted to get that information so other that are can take a look at the basics. There are other forum members that really know about these configurations.
That’s the question to be answered, a misconfigured APIM will, well, misbehave.
Nevertheless, since you mentioned that everything is working as expected but this, it’s a good idea to save your current APIM’s asbuilt so that you have a very good backup to go back to should you need to.
It’s always recommended to take backups from known good configurations before changing things.
Thank you SaNdMaN. I’ll figure out how to make a back up. I may already have it as the original group sent me a new ACM file to go with it? And that’s what I put in the car.
What’s also internesting and maybe not noteworthy is that when it originally arrived (before the new ACM file), the camera wouldn’t work, but the screen would change showing the car in reverse and with the reverse sensor blocks that would change from green to red.
If the only thing changing is the ACM files, that just makes me think it has to be a configuration piece. I just don’t understand enough of it to know what to change and where.
I don’t know how to Thank You enough. Unfortunately I just landed and will be gone for 3x days, but will try to program this in when I get back. I will let you know how it goes! Thank you so much!
Thank you for your help. We have a small victory! The system at least knows it is in reverse at this point! When shifting to reverse, the system recognizes it and has the car with the reverse sensor bars. Camera still isn’t coming on automatically, but definitely getting closer!
Any other ideas of which lines in the APIM may need to be modified?
Change
7D0-02-02 8200 0008 0065
to
7D0-02-02 8200 B008 0000
(I placed 00 at the end of the line and let FORScan calculate the parity when you write the line.)
This changes the Parking Distance Control Architecture (PDCA) to CIMCA.
Thank you…I followed your instructions and changed it. Forscan gave me an error and said I was trying to write an incorrect value? It let me do it anyway, and the B stayed in the As Built data when it was done. It assigned a “15” to the last two digits (maybe that’s what you were referring to with letting it assign a value?).
Unfortunately the camera still didn’t come on. But it still knows it’s in reverse.
Also not sure if it’s worth mentioning, but I have another one of these stick shift cars that is a titanium. It came with the 8” screen and after it was swapped to sync 3 the reverse camera still worked on it. Any possibility of something worth while in that car’s “as built” data?
I’m so grateful for your help. Thank you so much.
Comparing the asbuilts, I recommend these changes.
Change
7D0-02-02 8200 B008 0065
to
7D0-02-02 8200 0000 0000
Return the previous value and set the ICP to CAN.
Change
7D0-02-03 0405 E5
to
7D0-02-03 0005 E1
Turn off CS.
You did this already but listing it…
7D0-04-02 xx** xx
0000 DD
needs to be changed to…
0001 DE
01=Rear PDC (4 Sensors)
On the Manual Focus, the asbuilt has errors. The 7D0-07-xx lines need to be filled out with the vehicle data. Otherwise, the NAV will be off quite a bit.
Thank you again. I’m not sure I understood all of your message, but I believe I programmed everything per your instructions (see picture).
When you said “Return the previous value and set the ICP to CAN” is that what I’m performing by changing the code on that line or is that an additional step that I need to perform? Same with “turn off CS”?
Please forgive my ignorance on this. I uploaded the “as built” as it currently sits in the car as well as a picture of the rear camera working (so you know I’m not full of crap). It still just won’t come on unless I manually go in there and ask it to come on.
Here is the rest of the APIM “as built” data from the car. I’ll also attach a picture below this one for the “as built” data for the titanium.
Humor me or am I just uninformed…but other than the titanium having automatic temp control (visible obviously in the sync 3 unit), they are essentially the same car. Both 2015’s, same reverse camera and sensors, sync 3 upgrade came from the same source, both manual transmissions. Could I copy the “as built” data from the titanium and possibly fill it into the converted SE? I imagine it’s not that simple, but figured I’d throw it out there.
Below is the Titanium’s lower lines of APIM “as built”. And again, so grateful for your help.
We have success! Using the APIM file I saved from the Titanium not only fixed the reverse camera, but the screen brightness was always off previously (was on “dark mode” sometimes, never really very bright, weird symptoms, etc). That issue is gone now as well.
There is a new symptom (which I hope might be an easy fix?). I was wrong about one thing, the titanium has the premium sound with the extra speakers and subwoofer. The SE does not. While the audio controls work through the steering wheel and the radio dial, it no longer shows the adjustments on the screen (not the end of the world). But the audio adjustments will not respond (treble, bass, midrange). They move and the audio does change, but after a second or two they go right back to the maximum value and the audio changes back.
Think this could be because the titanium’s APIM file is configured to that premium sound system?
Definitely appreciate all your help. Getting somewhere now!
Yep, need to turn off or disable Smart DSP in 7D0-01-01. Probably 2 instead of A.
If you want to be adventerous, load the old asbuilt back and see if the camera functions still work. If they still do, then the asbuilt was corrupted and loading the other cleared this out. Just a curiosity…
