I decided to dig into using Forscan on the F53's to see if I could adjust any parameters in the computers to enable or change functionality. I will use this thread to document my findings and share info with the community.
Forscan is a software tool that can be used to interact with the ford computers in their modern vehicles. With the v8 change in 2020, the F53 picked up a lot of newer technology including a modern computer architecture. This theoretically unlocked the potential to make changes to how the vehicle is configured through a computer.
Information about Forscan here: https://forscan.org/
. Also there are good tutorials and guides on how to use the software.
There is a forum there too - but from my previous searches no one on a 2020+ has really dug into this, I was bored this weekend so figured I would take a look and see what I could uncover. Due to the Ukraine war, they have disabled the ability to register new users on the forum - so no luck in asking for guidance. I downloaded the forscan app for my windows computer and did the initial scans to see what modules appear. The following modules are installed on my 2020:
- Body Control Module
- Steering Column Control Module
- Instrument Panel Control Module
- Gateway Module A
I started with backing up all my modules to recover if I did something dumb. You can/should also get a list of all of the addresses and settings from Ford directly with your VIN so you can revert changes as a backup plan: https://www.motorcraftservice.com/AsBuilt
Next, you need an 'extended license' to enable modifications to the configuration in the software. Again due to the war you can't buy a license but the free 2 month trial is working so I am using that for now. Guess I have 2 months to do as much as I can.
I first started using the 'easy' mode to make changes where the software sees what is available and gives you a plain English interface to make a change. Unfortunately there wasn't much in there, and the one I tested to change the DRL configuration actually disabled my headlights all together.... wow there is a crazy amount of power in this tool - so use it wisely. So I backed out those changes. That meant I needed to manually make changes to specific addresses. But to do that I needed a legend to decipher the module addresses to figure out what is what. I looked at the forscan forum here: https://forscan.org/forum/viewtopic.php?f=16&t=4393
and saw the listing for the SuperDuty 2017+ 250/350/450 located here https://docs.google.com/spreadsheets...s1s/edit#gid=0
and figured they would be the closest match.
My initial goal was to disable the DRL's (see follow up post below for why), but after trying a couple things on the list, it didn't work at all. I then found my mistake - there is a difference starting in 2020. So you need to work off of the '2020 SD Model BCM' tab. I am not sure if the other modules are the same - as I have only explored the 'Body Control Module/BCM' at this point.
This was successful. Fellas, we are off to the races
