Forscan for 2022

[BroncOh]

Sweet. I’ll look next time I’m in it. I used the steering wheel and went to the settings and it doesn’t let me turn it off, just turn down the sensitivity.

Yup. I keep Lane Keeping Assist off. The painted road lines are shit here anyways.

 

[MiTremor906]

MiTremor906 you seem very knowledgeable with FORSCAN. I can do a little with it. I just talked to a guy that also seemed knowledgeable with it. He was helping me change the size of my fuel tank. He said do not make changes in the Plain English Modules.

I would like to know your opinion on what he said, and why he may have said that. Thanks for the help!!

Yes, you can get into more trouble with this. However, if you save your as Built before changes and document what you change, it's easy to revert back to the original and undo anything. Also if you stick to the main stream changes that others have done, you are at low risk. Feel free to send me a PM with any specific requests you have. I'd be happy to get on the phone and walk you though changes you are trying to do.

 

[MiTremor906]

Is there a way to turn off the lane keep keep assist thing. I don’t want to get notified constable how bad I’m driving. I’m planning on a 12hr drive in a couple weeks too, so I really don’t want to deal with it when I’m getting nice and tired while I’m driving.

Don't need forscan for this. As @BroncoHooves said, find the button above your display.

Haha. Didn’t know about that. Only have had the truck a couple days. I’m lost with all the buttons

I'm the type of person that doesn't like not knowing what a button does. Sometimes it gets me in trouble but very seldom do I not know what a button does.

The issue with the "Plain English" modules early in a new model year (22MY is new for SD due to incorporation of SYNC4 and the 12" screen) is that they are not all properly linked to the actual memory addresses.

Without boring you too much, every line that you see in the "As-Built" in Forscan or on Motorcraft.com is a memory address that controls certain functions. It is shown in Hexadecimal but at it's core level is binary - ones and zeros. The Plain English module simplifies that one step further by relating the actual function with the bit in words that are easy to understand.

For example, the binary address 11000101 will control multiple functions. The "bit" at the end I highlighted will change the function whether it is a 1 or a 0. This would be "C5" or "C4" in Hex. In the plain english it may say "Autofold Mirrors." For 22MY that may have been moved to a different memory location, however.
So you make the change, and it doesn't do what you expected. The issue is it may have changed something that you had no intention of changing.

Every address and function has to be tested, and early on there will be Plain English features that are just plain wrong because they have not been tested and verified and were probably assumed to be carryover from the previous year.

As time goes on more functions are verified and adjusted if necessary in the background so that the Plain English does what you expect it to do. Early on I tried to stay in the "AS-Built" module because there is a lot less chance of unintended consequences there, although it is still possible until all of those are verified regarding the actual function. I like to think of the As-Built as being a bit more surgical or direct.

It really is no different than your TV remote. There is a button that says "Vol Up." Pressing that turns that command into ones and zeros the TV understands. If you try to use it with a new TV it may or may not work until you program it and sync the button with the correct instruction set for that TV. Until you do that it may be necessary to walk over to the TV and turn the volume up there...

Same here! This is the same reason I don't like assuming that someone has programmed the Plain English correctly and tend to use the As-Built. A sign of my illness is that I also could not sleep easy assuming Forscan was recalculating the checksum for me. I had to understand the logic of how it was done so I could do it myself... I know, there is something wrong with me!

Thank for taking the time to explain that!!!

 

[Modman]

No problem. I was trying to recall an explicit example I had early on with my truck. I think it was with the double honk on exit... anyway, Forscan was on v41 IIRC and I tried changing it in the Plain English module. It didn't work so I changed the setting back and modified in the As-Built. I recently checked v44 and they had that fixed so the Plain English was mapped correctly. Every release should get better.

 

[Modman]

I will also state that I am no expert by far. I have never used Forscan before getting this vehicle, I just like to understand as much as I can about what I am doing so that if run into an issue I have a better chance of fixing it.

Thanks, I think I got it figured out. Changed the tire pressure....it was showing nothing but I heard you have to drive it awhile. We will see on the way home later.

How about this: "My dad has like the ultimate set of tools... I can fix it"

Yep, go enjoy a drive in your new truck. Sounds horrible doesn't it

I think we are cut from the same cloth as I'm the same. No expert but love to learn and understand. First time with forscan as well. Granted I over analyze and research everything so there is that.

 

[TThai]

I changed mine in the AS-BUILT and it worked fine. I can give you the correct revised address to enter so you don't get any error messages if you would like...

Hi. Modman, I did the same things on my 22 Lariat to add temp on gauges but not showing the change. What did I do it wrong? Thanks in advance.

 

[Modman]

@TThai can you provide your As-Built?

It should be something like this, although it may not be exactly the same:

720-07-01 8401 0AA0 0866

The highlighted character needs to change to a "5"
5 = ETD Always On • TTD Always On

ETD = Engine Temp, TTD = Trans Temp

Thanks Modman, I will give it a try after work. I only did it on the plain English that probably why it's not changing them. Will update them after changed.
