So I Added the oem nav from A 2012 Premium with the main body harness, Dash, evaporater ..etc
I got everything from a donor car

so when i went ahead and turned the key ON the pats was integrated and it was blinking on the cluster
And the touchscreen isn’t working but everything else does..so I went ahead and tried to reprogram the keys first thing I noticed is when I connected the OBD the sound now works when i take the OBD off the sound doesn’t work..

when i was trying to go through it with Forscan everything seemed normal I went ahead with module initialization and then reprogrammed the keys now there’s nothing blinking and everything seemed fine but when i took the tool off everything changed and went back to step one.. PATs enabled, blinking no cranking nothing..

I did everything again and I tried to turn the car without taking out the OBD and it was cranking but not starting..

can anyone please help me my car now is sitting with a premium leather interior making fun of me for a month now and it doesn’t start and I’m really close to set it on fire..

Excuse my poor English i’m not from US

 

This is going to sound really not great, but... you might be over your head and need to take it to a professional. Maybe even a dealership, although I'm sure that might be difficult.

These cars are very integrated, talking to all the modules, and disrupting those and not getting them reprogrammed correctly will cause just this issue. Especially since the body control modules and the engine control modules 'talk' through the instrument cluster in this car. If you swapped the instrument cluster, that's your problem. Or one of them. All the modules kind of have to know the others, and swapping them is not just plug and play like the old days... more like plug and pray... and then reprogram... and still pray...

I know it's a lot of work, but maybe you could temporarily plug in your old equipment and get the car to start. If so, then you can *one by one* swap out things until you find the culprit. I suspect its the instrument cluster itself causing your issue, but that's a *guess*, from afar. Again, at this point it might be a dealership/professional repair needed. If you're not extremely knowledgeable and have all the tools, you will literally chase this thing forever to no end, and you're already at an unfortunate milestone of thinking about torching the car... can't have that...

I hope that helps, even if it's not the answer you're looking for. And welcome to the forums!

 

Any chance that the FORSCAN tool isn't saving the changes to the car?

And am I the only person that thinks Forscan sounds too muck like foreskin?

 

Yeah I feel terrible now ..

well for the cluster I tried with mine and program it with Forscan but it was a no go .. so I tried the 2012 premium cluster and that also didn’t work..

i’ll be returning everything to the way it was but I’m not sure that after playing with it with forscan that it would work.. so it’s another thing that I’m scared of..

 

I actually wish that’s true.. that the forscan isn’t working properly..

but I’m thinking about programming it with VCM and I hope it would give me something..

any other thoughts would be highly appreciated..

 

Changing to the OEM nav does not need any programming. But what I am unclear of is if you also put in a different cluster?

 

no I didn’t change the cluster.. but i made a mistake when i was changing the body harness I changed all the modules with it including the PCM the “internal fuse box” I thought mine wouldn’t be the same as the premium so I changed and uploaded the as-built data from for scan and it didn’t work.. so now neither of them work..

Yeah I guess it’s missed up pretty bad bad .. so now I have loss of communication code and theft detected code ..

so what do you think..

 

Huh ...

Well is it possible to go back and put in all or your old modules and then reflash the pcm and PATs to how it was before?

As stated, no programming of anything is needed for the nav

If this is not possible, I have no other suggestion besides going to Ford and have them reflash all of the modules.

What modules did you change out?

 

so today I got everything back to the way it was .. but still .. the car is pretty angry.. I went ahead with the obd scanning tool.. whenever I put the obd the blinking goes away and i can crank it up but it’s not starting..

so I’m going back there tomorrow with one of my friends that works in ford I asked him about the Forescan and he didn’t have much to say but he told me he will try to reprogram the keys with the VCM using ford software “IDS” so we are hoping that it would work..

I want to take it to ford but here in the Middle East they don’t know anything about anything.. I’ve been calling them all week trying to make them understand what i done and what I actually want but no .. it’s frustrating so yeah .. fingers crossed to the VCM if it didn’t work.. then honestly I don’t know what to do

 

Hey Jim

so me and my friend tried to connect it to the VCM so we can program it the VCM didn’t catch any signal from the OBD port .. no communication whatsoever..

the only thing that works from that port is the Elm diagnostic tool .. whenever I put it in the sound from the screen and tge music starts to play whenever i take it out .. it goes off .. so I started to lose my mind .. we thought that maybe because it has a battery or something that maybe somehow it connects all the modules together..

so I’ve been going on at it .. in both cars trying to take whatever left in it .. i took the ABS module.. and i took everything the fuel pump relay that’s in the trunk the restraints module underneath the center console.. I took everything..

I’ve been going through all my stuff and found this little guy i’ll post some pictures I want know where I supposed to connect it and is it related to this mess ??

it says Gateway Modu

Might be the control module for SYNC? Only thing I could find that looked a little bit like it


https://dz310nzuyimx0.cloudfront.net...fdef303f73.png

 

That does not look like the sync module. I don't know what it is. I typed in teh part number, but nothing came up on the internet.

Call a Ford dealer and give them the part number. See what they say.

 

Hey David

Thanks man but it’s not sync module.. is it equipped with our middle east Mustangs that’s supposed to be connected with the screen for The GPS that’s has our maps programmed ..

not important

 

no it’s a module for GPS programming.. it’s nothing important..

So I want to ask you something Jim if the communication network wasn’t fully programmed or something there was not connected does this would cause The DLC to be interrupted and not gets reading from the port ??





for an example if i was trying to program this network and and one of the modules wasn’t connected do you think it would affect the whole network?? Or does every module works individually without the other ..?

another example if i was programming the IPC, but the RCM or the APIM wasn’t connected properly or messing.. would that affect The DLC?

because I’m gonna tell you something that happened two weeks ago .. i was programming the PCM and BCM and the cluster with my 2014 Base PCM with forscan while the RCM and RCSM (my seats were out) and I got a lot of loss communication codes
It didn’t work..

so I switched the Premium car PCM And SCT worked perfectly and everything seemed to be just fine I only needed to program the keys .. but the pats was activated so I tried with forscan to program it ..
After doing that, the SCT stopped working and loss of communication codes ..

 

Unfortunately, this is above me. I could not answer this for you.

There was a guy on here that could have helped you. You could try to contact him, but he has not been on here in years. Matt Honeycutt, known as zeroaviation.

 

No problem man thanks..

so here’s the updates for today.. I’ve programmed everything with Forescan and I got the PATs done so it’s not blinking or anything the remote worked again everything looks fine..

i was wondering if the 2012 mustang harness..( fuse box harness) and the 2014 harness are different from each other .. because I’ve noticed that there’s about 4 connectors goes from the passenger side that would connect to the BCM and the main body harness..

I noticed that they are the same plugs but the wires number and locations for some connectors are different from my car and the donor’s car

so do you think that’s the problem? And if there’s the the problem what should i do

 

Yes they did change some pin outs between the years as 13/14 used one amp to drive the speakers and they had 2 for the 10-12 cars. I am currently going thru a 12 body harness to compare to my 13as im looking to add heated seats. specifically im not sure of the difference I might need to grab the 12 wiring book.
