In your case: 727-01-01 3033 14FE 10B5
Focus on 10B5
First digit is 1. 1 means ECD Not Present, SANC Disabled, SESEEVESE Enabled.
Change it to 0. O means ECD Not Present, SANC Disabled, SESEEVESE Disabled

Second digit is 0. 0 means ANCM Disabled, ANCM Disabled, ANCM Disabled.
No action needed as ANC is disabled.

I am wondering what Ford does to deal with ese on systems with the B&O system being it has a subwoofer I looked up 2 different Mustang GT,s one with the B&O and one without it This is what I found
for their file
System with the B&O 727-01-01 3033 14FE 10BF
System without the B&O 727-01-01 3033 10FE 10B5
So if everyone says to change the 1 to zero in the third group my question is if the 1 is present on both groups how does ford do it with the B&O system with the subwoofer

 

[Fruitstang]

Don't actually understand the question - do you mean how they do it withOUT subwoofer?
As ESE is not using only the frequencies served by the separate sub, it works on non sub systems as well, probably just not going as deep.

I see what you're saying now. Basically, how is it that with their 1 factory installed sub there, why is it that the sound doesn't go through that like it would if you added subs for an aftermarket system?

I'm not actually sure if they have something to filter it, prevent that signal from reaching the sub, or it may produce that sound(although doubt this option). I'm not 100%, but I think I remember my installer saying when its enabled on vehicles it emits a buzzing sound.

Watched a few videos and figured I would make a short and simple guide here on how to do it.

Get Forscan from www.forscan.org: Make sure you use/get the most recent update.

Apply for the Extended License Trial: You'll need to enter some info. Hardware ID is gonna be for the Laptop. It tells you to wait 30 min and then hit refresh on the page. I did that and when I did the link appeared upon refresh for the Licence Key. Apply that to Forscan and says I'm good till 8/11/25.

Use their recommended ODB II Adapter. It was $59. https://www.obdlink.com/products/obdlink-ex/?ref=forscan I would not take the risk on using any other adapter, but what they recommend.
You are going to want to connect this ODB II adapter to the Laptop "while near an internet connection" so that the current drivers are installed.

Critically Important: Go to https://www.motorcraftservice.com/SetCountry?returnUrl=/AsBuilt Enter the info and save the AsBulit file which will be named as your VIN in .ab file extension. I would not change the file name, and I would recommend downloading it twice to have an extra copy. Before you close this page locate the line 727-01-01 and note the 3 sets of 4 numbers(write them down or take pic with phone). The set of numbers to look at is the 3'rd group of 4 off to the right. My 3'rd set had the ANC disabled already(set to 0), but the ESE was on(set to 1).
For ANC its the 2'nd digit x*xx where * is the digit to change if necessary. For ESE its the first digit *xxx where * is the digit to change of necessary. I changed my 1 to a 0. This is for the 3'rd set only.

You can leave the door open on the car for programming. I did it in 87 degree weather and didn't feel like getting cooked inside the vehicle with the door shut.

1. Plug in the ODB II adapter to the ODB II port which is at the far left under the dash. Other end USB to laptop.
2. Start Forscan software on the Laptop.
3. Turn on ACC(Hit start button once w/o touching brake).
4. At bottom left of Forscan screen hit the Connect button. It will do reading and ask if you want to save a module, which I did.
5. Next click the CPU looking icon off to the left. Scroll down at the right to find ACM(Audio Control Module). Mine did not have the Easy mode, only the As-Built option. Once the ACM is highlighted hit the Play/Read/Run button at the bottom left
6. Important: At bottom hit Save All to save that particular modules factory settings. I named mine ACM Original. Saves with .abt file extension. If you ever lost track or made a mistake you would go back to that module and hit Load All and pick the file ACM Original that you saved in my case for example to restore factory settings for that particular module.
7. Find the line 727-01-01. For me it was the top one. I changed my 1'st digit in the 3'rd set of numbers to a 0. 2'nd digit was alredy 0. Hit Write and ok on the warning popup. Now on mine the Write was 3-4 blocks down but still saved the change I made.
8. It will prompt you to turn Off the ACC, and then turn it back On. I waited to make sure all screens were off before turning back on to be safe.
9. At bottom left hit the Stop/Disconnect from module button.
10. At left Hit the Car icon and then at the bottom of that window hit Disconnect(button to right of the connect to vehicle button)
11. All done, and test changes. Started my car and checked the radio. Didn't drive it to see if any difference via ESE yet, but will update this if a noticeable change with it off.

Do at your own risk, I assume no responsibility for errors. Ok Lawyer speak done.

Really not that hard. To think one audio shop wanted to charge over $350 to do this. Found a better shop I'm going through and did it myself.

Edit 10/7/25: Don't force the ODB II adapter too hard when plugging it in or the cheap plastic surround will snap off making the cable become loose. I had to rig it to sit back in the hole/plug area. Also, I noticed no change in Exahust Sound with ESE off or ANC off. It is definitely required though as I talked with Car Audio installers and they said its a must to turn it off.

Thank you so much for this. Super simple and quick to do. Follow up question: Do you think Either ANC or ESE adds or has a subsonic filter on the built in EQ? I tried looking and can't find anything.

 

[DarkkMatter]

Im not sure about the stock EQ or if it adds a filter, but shop I took Mustang to tapped into one of the back rear speakers for the signal.

Subs dont produce sound till volume 8, but afterwards will 5-7, but its ridiculously loud when cut up. Cabin gain is great in these cars.

 

[Dark Sprite]

I hate the thought of artificial sound being plumbed into the cabin, it feels like a lie. I would rather be able to hear what my engine actually sounds like and if I want to hear that Track exhaust roar in an underpass, I'll roll down the windows, thanks! Surprising Ford felt they needed to do this with an na V8

 

[Dark Sprite]

I have made this change now (yet to test on the road but cold start sound from inside the car seems to be the same volume but sounds much more externalised):

Disable ESE (fake engine sounds through the stereo):​

​

Change: 727-01-01 BC33 14FC 103F​

​

To: 727-01-01 BC33 14FC 003F​

It looks like mine already had ANC off (this is the second zero in the last block, based on the table in the OP).

But what do I change to turn off the galloping (dum dum dum x4) upon start up (other than having my door closed and seat belt on before I hit the ignition!)?

I tried changing the "Chimes - Driver Belt Reminder" and "Door Ajar Warning" in the IPC module (easy mode) but these didn't have the desired effect and actually reverted some of my other settings to default (e.g. cluster to normal, tyre pressures to kpa, time to manual and clock to 12hr - hopefully no others, as reverting back to enabled on both of these I still had to change my settings manually in the dash), so I don't think that's a sensible thing to fiddle with...

A side effect also seems to be that whenever I switch the ignition off now it asks me on the dash if I want to "Alarm System Turn off motion sensors? Yes/No" - how do I fix that?

 

[Sofa King]

ANC is only on convertibles... the motion detector prompt can be turned off in the menus.

 

[Dark Sprite]

Drove it on the highway today with ESE off set to sports exhaust and the sound inside the cabin is definitely not there anymore, the engine sound is more raw and less refined than the soft growl the speakers were playing. Not sure I prefer the sound but I definitely prefer it being real.

 

[DT-GT]

I disabled the ESE in my GT convertible today and the difference was immediately noticeable. Much quieter in the cabin. I like it.

Same here, although coupe. Much quieter in the cabin.

I had no plans to upgrade the exhaust b/c I thought the car was loud enough. Rethinking that now
