"Hands on the Wheel" Alert 🤬

[npole]

Nope it doesn't appear, that is the reason of why we're blaming Ford. The only way to not have that popup is to disable the lane assistant (by the menu or by double tapping the button), but we want to maintain the lane assistant and disable only the message (but we couldn't find a way).

I think that hands on wheel alert is possible to disabled it through Forscan. I scrolled to all lines ones and there are some adresses that could probably disable that hands on wheel alert.

Just need the time to try them all out and see what they do.

I know that European spec Mustangs have more mandatory chimes and alerts enabled than the NA Mustang.

I compared the EU Mustang with the NA Mustang and found out that for example in the APIM module in adresa 7D0-09-04 xxx* xxxx xx-- (Information Chimes) IC, is turned off on the NA Mustangs and turned on on the EU Mustangs.

So there must be a line sonewhere, ahere but chimes and alerts are turned on and where we csn turn it off. I'm pretty sure I saw all the lines and know exactlt which ones to try if I had the time.

Okay I found the adress where the hands on wheel alert is written under.
The only thing that is unknown is what we have to change it to.

Now I understand why auto Hertschel in Germany did not want to give us the numbers.
They tried all possible values until they turned it off and they can only turn it off for you if you bring your car to them without letting you know what values you have to change it to.

This is the adress:

724-02-02

004A

***0

0039

Since there are 3 numbers to change and we have 0 to 9 and A to Z, there are 46.656 possibilities.

All Mustangs are coded with C00 and this means it is enabled.

The most logical change to disable it would be 000, A00, B00, D00, E00 or F00.

But there is one good change. Are there any Mustangs that don't have this feature?
These Mustangs may have this adress coded in "disabled" unless Ford is a smartass and coded it the same as the Mustangs with this feature to make it more difficult to find out what values we have to change it to.

Hands on the wheel was almost a deal breaker, but the dealer said Ford was working on a software fix, so I took a punt and bought the car.
Then I discovered that lane assist off also disables the hands on warning, so I'm a happy camper.

 

[npole]

But the lane assist is very useful on certain circumstances (used it often on the S550), so you are "forced" to disable a useful (for some ppl) feature, because another doesn't work as expected. So I paid for something that I would like to use, but I couldn't (it doesn't matter if some others doesn't care...).

Thanks for your work! Just out of curiosity and to get a better understanding: What makes you so confident that this needs to be the address where the warning is stored?

Thanks!

Just to make things clear. We can only be sure if we manage to disable it.

So this is only theoretically.
The hands on wheel is something that is controlled by different modules.

Since it is a feature that comes with the Advanced Driver Assistance Systems (ADAS), we have to look in different modules.

Since this is a steering thing, there should be something at least in the steering module that send a message to other modules to act.

The only adress in the steering module (SCCM) that has something to do with monitoring steering movement is the line I mentioned. It is called, DrvInputRequiredTimer (DIRT).

This means that there is a timer set that gives a signal to the other modules after a specific amount of time when the system doesn't measure any driver input.

This is exactly how the Hands on the Wheel works. After a specific time, you get the message. That's the driver input timer that kicked in.

So this means that we can either extend the timer, shorten the timer or disable the timer.

So measure the time period, and convert that decimal number of seconds to hex.
Do you see that hex value (or values +/-) in the line you reckon it is?

Our cars are set to C00
C in HEX means 12.
In your theory the warning starts after 12 seconds with no driver input. But I haven't had any warning yet since I can't use the LKA, LCA and all other ADAS features.

Since Forscan only has 0 to 9 and A to F, and we know that our cars are set to C00, in your theory this means C00 = 12 seconds

A00 = 10 seconds
B00 = 11 seconds
C00 = 12 seconds
D00 = 13 seconds
E00 = 14 seconds
F00 = 15 seconds

Hopefully 000 means disabled or you will get the notification all the time

Well, this is easy to find out, but I can't test this out since I'm living on a small island where these features don't work. We don't even have striping on the road.

An island sounds wonderful!

Only when you're on vacation. Not to live there perminently.

Thanks for your work! I am not keen on trying this out to be honest (a bit afraid to break something as I lack the knowledge) but I will try to turn off Information Chimes, if that's disabled in the NA Mustang!

No, 0xC00 does not = 12
0xC00 = 3072

You are referring to 3 bytes, not just one, so make your mind up!

I have not measured how often the nag comes up, because I double press the lane keeping button (thereby turning it off) as a part of my start routine, along with turning off the ASS.

Re-read my suggestion above, but I think you are barking up the wrong tree in this case.

I'm just trying to find out what it could bez nothing more. I have zero experience in HEX and zero experience in bits.

The only thing I said was that I found the adress in SCCM and that there are 3 values to change and that all Mustangs have C00 als a value.

You came with the suggestion to convert the decimal to Hex, which I totally don't even know what that means, so what I did was asking ChatGPT what C means in HEX and that was 12.

That's how I came with 12 seconds. Nothing more nothing less. I was just thinking loudly so that others can see how I'm thinking so that others can add their own knowledge in this subject. With the knowledge of us all combined, it's possible to figure this one out.

So share your knowledge with us if you know how it works, that's more valueble than charging at me while I'm just trying to find out the right numbers
