2021 F-150 XLR 5.0

Post by AlgoaTX »

Not working ;
Had a Explorer ST 2021 ( did not like it at all )
but the newly purchased FORScan worked fine.
Could change and save settings .
NOW in the F - 150 ; can`t do a damn thing .
Like Ford locked the ECU up completely !
What`s up with that, and is that the case ?
Anyone had the same ?

There have been rumours that Ford is encrypting some of their networks but it would be a good idea to Email Forscan at this address contact@forscan.org and follow the instructions at this Page https://forscan.org/contactus.html.
Debug instructions are at the heading "Providing FORScan Debug information" to find out if this vehicle is in the data base or it needs to be added.

Being that this is a 2021 vehicle and may have a connection protocol that Forscan has not encountered as of yet, this particular vehicle may not be in the vehicle data base!
Do not PM me as I am not an Admin nor am I a member of the FORScan Team and all questions should be asked and answered on the Open Forum so all can benefit!

Ford did not lock up the PCM or any other controller, the spreadsheet or what ever configuration was accessed with those changes within the control units, infected network access and behavior.

Operator error!

Just because some genius decided to create a "how to spreadsheet" on their model, doesn't necessarily mean that it fits other models with other installed or configured controllers. These modern Ford models are a rolling network on steroids.

Think about this, remove or change one startup system file on a Windows machine and expect it to fail.

This is now becoming a "serious problem" and Ford planet is coming to this site to "repair / fix / re-adapt / reconfigure / re-start" the HEX data that was never intended to be manipulated.

The entire network is in constant communication with all the controllers at all times. Inject something that never did belong to one network controller and the entire network "listens to the unwanted injection" and definitively reacts to those changes.

FORScan is intended to diagnose, read / clear faults and configure a vehicle "within the specifications of a Ford repair manual".

These models with complex and protected networks are designed to be accessed with the VCM 3.

Wikipedia: CAN FD (Controller Area Network Flexible Data-Rate) is a data-communication protocol typically used for broadcasting sensor data and control information on 2 wire interconnections between different parts of electronic instrumentation and control system.

That's a Wiki page, you should read the training sessions and the raw data captured on a CAN analyzer. That is something to behold.

None of what Ford owners are "hacking" isn't even described with a Motorcraft subscription.

You would think, saving the original (very few even think about that part), taking incremental steps with small changes to "test" a controller adaptation would be considered.

Nope, read a forum, get a sheet or some mickey mouse change and all of a sudden, one dives into the pool and just realized there's no water in it.

I do wonder however how many of those forums actually "guarantee" those adaptations?
Do they pay for the tow call? Will they pay for a compete and global update of the installed controllers?
How about a miss-configured Driver Assist System, that takes equipment using ADAS software.
The most expensive part is the paper weight that is not programmable any longer or "bricked"!
Worse yet, an adaptation that created a traffic accident!

Who's responsible for that? FORScan? The "other" forums?

Want it fixed? Have a Ford dealer perform a global update and reconfiguration.
Do not ask for help in PM. Use the forum to ask and answer questions!
