Anybody able to enable Auto-Hold on Bronco 2026 OBX Lux?

[rugedraw]

I just remembered I have a 2025 Bronco here at my store that got traded in. I can try it on this one if you guys want. I have my laptop with me.

For sure! Try both the one for the F150 and this one with the "F" if you can. Just make sure you have those 3 boxes on the 760-03-01 reg key otherwise it has a MY 24 setup. Thanks!

I have zero interest in attempting the AI suggestions, tbh.

Edit: Auto-hold may also need to be enabled in the IPC. There is a bit there for it. I'm going to plug into now and FAFO.

The biggest benefit of flashing a 2.7L Lux package is that you can skip the PCM Initialization / Relearn service function. Because your powertrain control module is already configured to accept radar inputs, shifting the ABS profile to F rarely triggers a hard module lock.

The Rest of the Setup

1. Use FORScan's non-As-Built (Plain Text) modes to set Adaptive Cruise Control Stop & Go (BodyCM), Auto-Hold (APIM), and Auto-Hold Indicator (IPC) to Enabled.
2. Clear any temporary communication fault codes (DTCs) triggered during the programming sequence.
3. Cycle your physical ignition off and back on. Your new Auto Hold slider switch. .its telling me not to do a pcm relearn with the lux package maybe that’s locking it up . I’m Not feeling to comfortable yet with the auto hold mod .

@soloist What change did you make to get auto-hold to show up in driver assist?

Edit: Nvm, I see it. I had to reboot the APIM again. I made the change to the IPC and ABS but it won't turn on. I'll mess with it some more.

Can't get it to work. Reset the 4 modules, did a PCM relearn jic, too. Autohold buton cannot be toggled on. No codes after making the changes to the ABS, though. Something is missing, but not sure what. I'm sure it is possible.

Edit: The change in the ABS didn't take. I changed it to the C and got all the driver assist codes. PCM relearn will not clear them. Going to revert it back to how it was.

I'm not ready to give up on this. I am going to do some more digging to see if I can think of something else to try.

Yeap, we are on the same spot, I experienced exactly the same on mine. The only thing I didn't try yet is using the F150 spreadsheet that at least for this mod it looks pretty similar

If you want to try the AI suggestion about stop and go in the BCM, it is changed here:

The Bronco I have here shows 8C, so it would need to be changed to 90. I can try it, but it will have to be later. I'm at work and need to take care of a few things.

However, stop & go may be tied in to TJA (traffic jam assist) in which case, it would need to be enabled in the IPMA here:

That sounds promising! I'm out of town now but I'll also be able to try some stuff once I get back. Maybe we all end up being the first ones to enable ACC STOP AND GO on these 25-26 Broncos

That's gonna be tough because stop & go also needs to be enabled in the ABS module and we are working in the dark where these trucks. Due to cybersecurity changes Ford made, Livnitup cannot make new spreadsheets anymore. At least not for now.

The configuration rule remains identical for a 2025 Bronco Raptor sharing that exact same 3480 004C DF4Ablock chain. [1]
However, because you are dealing with a Raptor, there is a crucial warning regarding engine tunes that you must account for before performing this flash. [1]

The Hex Modification
Just like the 2026 2.3L EcoBoost model, you must change the initial tier value from 3 to F to enable the automated stop-and-go braking subroutines. [1]
The checksum block auto-adjusts based on the data bytes, resulting in this exact target line:

• Original Line: 760-03-01 3480 004C DF4A
• Modified Line: 760-03-01 F480 004C DF0A [1, 2]

Critical Raptor Step: Check Your Engine Tune
Many Bronco Raptor owners run the Ford Performance ProCal tune or an aftermarket engine calibration. [1]

• The Risk: If you attempt to run the required PCM Initialization / Relearn service in FORScan while an active engine tune is loaded, the sequence will fail or potentially lock up the powertrain module.
• The Fix: Before writing the ABS changes, use your ProCal or tuning handset to restore the truck's PCM back to the factory stock tune. [1]

The Raptor Flash Sequence

1. Flash to Stock: Revert any active performance engine tune back to factory defaults. [1]
2. Modify ABS As-Built: Open 760-03-01 in the ABS module, change the first digit to F (changing the checksum block automatically or manually to DF0A), and click Write. [1, 2]
3. Run PCM Relearn: Go to the Service Functions (wrench icon) tab, select PCM Initialization / Relearn, and follow the on-screen configuration prompts. [1, 2]
4. Complete the Text Modules: Flip the plain-text toggles for Adaptive Cruise Control Stop & Go in the BodyCM, Auto-Hold in the APIM, and Auto-Hold Indicator in the IPC to Enabled. [1]
5. Clear DTCs & Cycle Ignition: Wipe out the temporary communication fault codes under the DTC tab, turn off the truck, cycle the doors, and turn it back on. [1]
6. Reinstall Your Tune: Once the dashboard is clear and Auto Hold works, you can safely reload your ProCal or aftermarket performance tune back onto the Raptor. [1]

Are you running the Ford Performance ProCal tune on this Raptor, or is the powertrain entirely stock?

read this you might want to get more input before you attempt this mod change .

I am still all stock for the engine, my biggest hurdle is the fact that I do not have the option to read or write on the 760-03-01 line. I am not sure why the code is so different for the Raptor, it is frustrating for sure. I will keep researching, I already played with it some and was unable to get it working, it just broke my cruise control and I rest everything back to original to get it all working again.

Why do you say that? The screenshot you posted shows the write button for those blocks. Are you saying when you try to write there you get an error and the change won't take?

Ok, I plugged back in for another round of FAFO. I could not get it to work, but I got a little further along before the codes started popping up, and this time, the only code I got was for precollision not available......not the buffet of codes I got earlier. I even tried the AI suggestions.

In this order, I enabled AH in the APIM and then AH in the IPC. I then enabled stop & go in the BCM here:

726-16-01

xxxx xx90 xxxx

Then went to the ABS and wrote this (first bit enables stop & go according to AI and second bit enabled auto-hold as per the working theory):

FBxx xxxx xxxx

Interstingly enough, no codes. However, auto hold could still not be turned on in the tochscreen. So I went into the IPMA and enabled (in theory) TJA or traffic jam assist here:

706-01-02

xxxA xxxx xxxx

Wrote the change, and at that point, I got the no precollision assist error and auto hold could still not be enabled. At that point, I set everything back to how it came.

I'm sure you did but did you close all doors, buckled up and put it on drive before trying to enable Auto-Hold? Also resetting the infotainment system could help, you need to press Power+Skip song for a couple of seconds
