Is Lane-Keeping Steering Wheel Pressure Adjustable?

[McE]

First time it happened my wife looked at me like I was fn tarded. I had to explain myself and she wasn't buying it

I think I speak for most of us when I say we’ve probably given our wives plenty of reason to question that

Unfortunately, I have been chasing this for two years and have not found the spot to adjust with Forscan, yet. I know it is there, somewhere and hope I get lucky one of these days to find it. I am looking in the PSCM and IPMA as I know those work together and feed back through ADAS, but I am not sure if other modules are involved, such as the SCCM and IPC. What I have found is the LKA/LC seems to sense/detect movement and resistance against movement via the EPAS (controlled by the PSCM). I verified this using an ankle weight on one side which effectively kept the message from appearing.

For any that have the Fox ATS steering stabilizer and if set above 18 clicks, the steering is so tight that the system nags damn near constantly. Ask me how I know that!

You haven't been able to find the sensitivity adjustment in the PSCM, IPMA, or SCCM As-Built data because it isn't there. The torque threshold for the "Hands on Wheel" warning is not a configurable toggle or hex value in the module's As-Built configuration. It is hardcoded directly into the EPAS safety firmware/calibration file by Ford and their steering supplier. Because it’s baked into the base calibration for NHTSA/safety compliance, FORScan cannot adjust it.

I used ChatGPT and obtained this:

“Ford’s 2026 owner’s manual confirms that the hands-on-wheel system is looking for steering activity, not merely physical contact. Ford says a light grip or light touch can be interpreted as hands-off, and specifically instructs the driver to apply slight force to the steering wheel if the system doesn’t detect the hands.”

Ok know I know - case closed.

I'm a jerk and i hate chatgpt.

So... I had discovered after the fact, after ordering a Bilstein 5100 steering stabilizer/damper, that the Bilstein being gas-charged (which I'd always known but conveniently overlooked in my enthusiasm to "improve" the steering damper on my 11,000-mile, 2025 SD Tremor wearing relatively lighter weight wheels and tires...) I discovered that the damper wishes to expand on it's own. d'oh. This would push the drag link to one side, effectively steering the truck to the other, then requiring me to make constant adjustments in a manner resembling a bad wheel alignment. No thank you.

Why would I want that to happen to a truck that presently drives perfectly straight when on any road surface largely devoid of crown or camber?

So I returned the Bilstein steering damper unused and in it's original packaging for a full refund.

I realize too that folks may be trying to solve a different issue w/ their EPAS systems (my truck has one) so you will please forgive my intrustion here.

That said, since I wish to preserve my truck's excellent! steering, I must either go with a dual/opposing-force steering damper setup - OR - remain using the OEM twin-tube steering stabilizer. Since we're all well aware (or should be) of the Ford damper's minimal *useful* lifespan, one could simply replace the worn Ford damper w/ another, new unit every few years or every 25,000 or 50,000 miles or whatever other interval you may choose.

Cheers.

Been messing with it more and more

Still don't like it, but hating it much less lately

We let it throw a fit and see what it would do if you don't respond to the warnings


It was pretty hilarious.


Try it.... you'll see.





End result was sitting parked in the middle of the road with flashers on.

After a bunch of other funny stuff happening.

Ya, the brake check wake-up is fun to scare the wife.

My son and i could not stop laughing.

2 idiots sitting in the middle of the road giggling like school girls.

Meanwhile... the truck sounds like it is going into self destruct mode.

I've only gotten as far as the coffee cup. Now, others have definitely tested the precollision assist by jumping right in front of me and that is a hoot to say the least. Dude/lady tried to kill me a couple of months ago just popping across my path on a country road. Between the precollision assist and my evasive maneuvers, I ended up half in the ditch and kept momentum to get back up the damn thing before I ended up all the way in the ditch....

Wow.

I turned that pca off before leaving the dealership.

It really screws with overtaking big trucks, tourists, and octagenarians.

My typical commute is almost entirely 2 lane highway, passing is a must .

Had to slow way down this morning to let Bambi and his mom cross the highway.

Most of our deer seem to stay out of the road though. I think muleys are a bit smarter than whitetail in that regard. You don't see a lot of big game get waxed here. .... relatively

I have mine turned off. I work up in northern Alberta and BC and share roads with large logging and oilfield semis so I tend to drive closer to the shoulder. The lane centering doesn’t like me that close to the line so I have to fight the wheel to keep me shoulder close.
I do use the lane departure though but with the lane centering off.

I generally agree with your assessment in a normal setting. However, what I am chasing is a possible PID that exposes the PSCM steering shaft torque registered or applied. Based on that, I can record and estimate the parameters that are used for the threshold to warn. I am trying to figure out if the method used is a calibration scalar or a variable table. I am seriously hoping the method used is scalar because if it is a table such as different torque threshold depending on speed then there is absolutely no way I could make a modification without rewriting everything. If scalar, there is a chance, albeit tiny, that I would be able to modify, not necessarily with Forscan , and eliminate. The reason I still suspect that I can do it is because of how Blue Cruise works in a hands-free mode. Even though the Super Duty rigs are not BC most of the underlying modules are there so it's just a matter of whether or not I can find and successfully modify or interrupt the trigger. If I had a BC equipped vehicle, things would be quicker, maybe, but there are other issues with that too as I don't want to ruin an otherwise functioning system just because of my OCD and an annoyance.

On the Fox ATS, I actually like it but more importantly, I am not worthy of the Dual setup... yet.

…why tow hooks come as standard equipment…..

I can have my hand firmly on the steering wheel while using Lane-Keeping, yet it still gives me a warning to apply more pressure.

Can Forscan adjust the amount of hand pressure on the steering wheel?

To spoof it, just fill a bottle 3/4 with water so it’ll slosh and jam that into the steering wheel. That’ll make it last a couple of minutes assuming the road stays mostly straight (which is a weak assumption).
