Change lane keep to lane centering?

[ChillinDylan]

I love this kind of stuff. Unfortunately, I don't have one of these cars myself to experiment with stuff, but I have learned a lot about these things dealing with issues my truck had and helping a lot of people on the F150, Lightning and Mach E forums. You'd be surprised how similar all these vehicles are with each other in many things.

Well I’m happy to try things and experiment but I don’t have a lot of knowledge on the research part, or much time to learn and do that. I work 3 7 day weeks away from home at a time with a minimum of 80 hours per week, but usually more like 100 or even 120. And then my one week at home is pretty full of trying to take care of home stuff and spend time with the family. The only two things I don’t like about this car when it comes to the tech is that it doesn’t come with is the lane centering and remote start. And it’s silly since a Honda civic Si comes with those things in a far less expensive, less premium car. The remote rev feature would be nice too, but idk if that one would be possible on a manual. The other two though I fully believe are possible with simply coding/configuration changes

I took our 401a premium on a 500 mile round trip last Thursday. Never drove it more than an hour at a time prior.

Definitely has lane centering AND lane departure modes. Two entirely different things.

I never realized it could do the centering , first vehicle I've had that can. Pretty neat , and no bouncing side to side like departure mode. I was quickly annoyed by the hands on wheel reminder , which was very nitpicking about hand placement.

I turned it off. Felt weird letting the car steer for me. It was like I was back in drivers ed in one of those dual steering dual brakes car they would have back in the 90's

Probably never would have tried to use it if I hadn't read this thread. Its definitely on our 401a auto though.

I thought it was only the 401A package.

And for the topicstarter. At the moment I'm not close to home for a few weeks. But I would do what Sofa King told you, but make sure it is a 401A package to be on the safe side.

Oh, I think you may be right... I think any of the x01A packages with auto.

Sorry @chillinif that Vin isn't a x01A package (not sure)... you may have to look at bit yourself if it's not.

The one I posted on post #65 is from a 401A vehicle.

Background: 301A GT PP manual with Adaptive Cruise I retrofitted no DTC’s been working for over a year without problems.

Ok guys, going to try to articulate where I am at with this the best I can.

Good news I have no DTC’s and I have the proper Lane Keep Assist (LKA) Lane centering icon on the Instrument cluster Pic 1, Center screen shows lane centering enabled.

Bad news is when I go to engage Cruise it just shows the greyed out line as if I was not moving, unless it picks up a speed based on the tolerance I have set in the intelligent cruise control example if a tolerance of 10KPH in a 30KPH zone it will set the cruise at 40KPH. However it does not actually set it, it just stays grey. Similar situation if you ever try to engage cruise control in track or drag mode, it just wont let you. When I don’t have a speed sign on the instrument cluster, I get the same as if I was parked, which is "tac" or "dash" next to little cruise icon.

The last pic is what it looks like when cruise is working.

This leads me to believe that the car with the settings I changed does not “know” if the car is moving because I have not put into drive? (Can’t do that in a manual!)

All the changes i made are based off the Asbuilt data posted above compared to mine in the fields i thought were relevent, anything to do with stop and go, traffic jam, cruise etc. I cross refrenced each line to the data base and changed based on what the automatic data had, less stuff like country, PP options, transmisson options etc.

That’s kind of where I am at right right now. I listed the settings I changed, if you want to do this just save your original settings in each module and switch back and forth. I have gone back and forth now a handful of times.

Found something else in the IPMA. Below is from a 2025 Mustang GT 401A automatic:

Here is that same line on a 2025 401A manual:

Assuming the LCA is lane centering assist and LKA is lane keep assist, I think it is worth a try at this point.

There is also something about lane keeping aid in the SCCM, but both the auto and manual have it enabled. I have looked through everything else I can think of and I am out of ideas after this.

@rugedraw @robotninjasrule I’m definitely going to try these changes and see what happens as soon as I get back home from work and to my car. Looks very promising. What do you think about trying “F” since that seemingly puts everything that line of code controls to on?

You can try. As long as everything that's been tried doesn't spit out a code for incompatible config, there is still a chance this will work.

@rugedraw

I will give those a go, i am not sure if they will have an impact because they are under the "Customer Setting" my understanding those can be changed in car some how, guessing on the center screen.

@ChillinDylan

That's great, let me know if you need any other data, i did a lot of changes a while back to get the Adaptive cruise working and the TSR now that i think of it.

I am going to look into the "CCM" module when i get home. I cant remember if it has any other settings than VIN. I think our problem is that we have 2 types of adaptive cruise, the one that is linked to Lane Center Assist (LCA) is the stop and go, which could be imbedded in many modules. I remember getting the speed limit button setting to work i had to even go into the PCM and enable it.

Keep it up gents!

I agree. I am reaching at this point.

@rugedraw sometimes the things that seem far fetched or like a stretch are the right things. I wouldn't be surprised if all of the driving systems and modules work together for this one. But I definitely believe it is possible, and I really don't think the transmission type would actually stop it. The manuals know what gear they are in and know whether or not the clutch is pressed and seemingly how much it is pressed too, so I think all the necessary parameters and information is there, its just a matter of figuring out how to get everything to tell each other the right things.

@robotninjasrule I'm impressed that you got adaptive cruise working on a base car in the first place. I am curious about what you changed in the PCM to get that working, I'm thinking that maybe it has something to do with this too.

This might seem like a stupid question, but what about taking the asbuilt data from a 401a auto car and loading all the differences into a manual 401a car? Like everything that is different besides anything that is obviously functionally specific to the transmission itself. For example, my car should in theory be pretty much identical coding wise to a 401a auto B&O non PP car minus anything that is different because of the transmission, which obviously we know this lane centering and remote start/rev are a couple differences that auto cars have, but what, if anything else do they have? If thats really the only differences then maybe it would be easier to do that and then work backwards from there? If loading all the differences in makes lane centering and/or remote start work, then could just start changing coding lines back to stock one at a time until something doesn't work and then put it back. Definitely sounds time consuming, but so is trying to find each individual line of code to change one at a time and then seeing if anything changed

@ChillinDylan For ACC and IACC, it makes sense that there are things needed in the PCM and ABS since the vehicle accelerates and slows down on its own as part of the operation. However, this is not the case for lane centering and lane keeping.

At this point, I am not sure if lane centering will work without enabling TJA or some other form of driver assist feature. One thing may be depedant on the other based on how everything is coded. I have asked for the help of one of the gurus on the F150 forum on this subject to see what additional insight I can get from him.

 

[robotninjasrule]

After looking at my notes the only change I made to the PCM when I added IACC was

7E0-03-02 xx*x - xxxx to a 2 or 3.

The above change was to make the Speed limiting feature (the button on the bottom left of the left side steering wheel controls)

I like the idea of using the F150 even the maverick data / forums to help. It’s what gave me the idea to add the IACC in the first place.

The setting in in the PCM that I am interested in is;

Brakes-Anti Lock (BAL)

7EO-03-04 x*xx – xxxx

Asbuilt data posted from above 2525 - 0111
My data 2501 - 0111

On the surface this appears to be a different setting however when you look at the spreadsheet that setting is actually x**x 2 digits, and the list on the spreadsheet does not show either 52 or 50.

I may be fighting an uphill battle because of some key differences in base vs prem. Like how Blind Spot system is "hardwired" on base and "Network" on prem.

I have been comparing line by line using the Ford Asbuilt Explorer ( google it, work computer won't let me post a link to that site) and cross referencing every item using the spreadsheet.

 

[rugedraw]

Well, I have some bad news. The PSCM and the ABS module on the automatic and the manual cars have different firmware.....the calibration files are different. This most likley means that to get this to work, we would need to obtain the raw calibration files using FDRS to flash them with FORScan and then make the changes needed that are approprite for a manual transmission car on a line by line basis.

If that is the case, this means that a level of FAFO is required to get this to work that most people will not be comfortable with. The IPMA itself has 4 different calibration files......I have no idea which one (or which ones) would need to be flashed in order to get the correct firmware that includes the events for lane centering to work.

 

[robotninjasrule]

@rugedraw

Thanks for looking into that!
Not really interested in doing firmware updates with FDRS, its too cost prohibitive. I think it cost me like 150CAD for 2 days of access, they updated the pricing model a while back to some subscription nonsense.

It may be just that simple, i was able to get it all to work without DTC's just cruise would no longer engage.
