FORscan not working on 2025 Expedition

[rdunkleenr2d]

"2025+MY Ford and Lincoln models are supported with a 'best-effort' commitment. It means that work of FORScan on 2025+MY is not guaranteed and not promised." This statement from the developer is true. I tried making some changes on my 2025 expedition and they did and did not work. First all changes were made using the "easy mode". I tried disabling the lane keeping and lane centering systems and ended up with an error stating the system was inoperable and I need to schedule service. I tried to disable the auto start/stop and that did not work, the engine stopped at a stop sign. the last change was trying to disable the forward collision system and it only disabled one part of the system. I verified this in the vehicle settings-driver assistance screen. I also tried to change the number of blinks for the lane change turn signal and it was still blinking 3 times. Now on this one I used the as built screen for the SCCM. I made the change but I came up with a check sum error in FORscan. I just said OK but it did not change the number of blinks. And yes I used a HEX calculator to add 8 HEX to the default value (5 HEX + 8 HEX = D HEX). So at least with a 2025 Expedition I would use FORscan with a lot of caution.

I read “somewhere” that Ford was looking into disabling Forscan. Guess it’s really happening.

My note this morning is just an observation as I have no actual facts (yet).

The operating system that Ford uses now for the critical systems seems to be more complex than the fourth Gen. As with any proprietary software you would expect it to be safe from hacking since the critical elements of the software are not "Open Source".

The truth is all software can be hacked, but at that point you need to run your own tests without simulation, and that gets expensive fast.

Tuning the Engine ECU is not what I am talking about here but perhaps even that will get locked out.

I want access, and I will get it, however I do not plan on making any tweaks until the warranty expires. There should be plenty of time to learn from history by then.

The other way to do this is by tricking the input at the field device. When it comes to cameras and simulating images.... good luck with that.

Keep pushing forward.
