2021+ F-150 FORScan List / Database / Spreadsheet

[Jimmy Young]

You need to run the PCM/TCM relearn procedure once you change the value.

Today I gave it a shot. I did the PCM relearn it said successful. Rebooted and went back into FORScan. DTC and PCM was still showing fault U0422:00-2F
Did a DTC reset again and it still comes up.

can’t do the TCM relearn as I don’t have that module listed as available.
Any other suggestions?

That's ok, it's only the PCM relearn for our trucks.
What are your values in the BCM for:

726-15-01	xxxx	xxxx	**--
726-15-02	**xx	xx--

?

Does this delete the alert beep on the tailgate handle button when trying to open the power tailgate by hand?

Also hoping to find the delete option for the Rear Brake Assist message pop-up that now comes on with each Reverse action, since I have the menu option turned off so it doesnt (sometimes)falsely brake when im plowing in my driveway.

I did updates in fdrs. My subscription ended before I was able to calibrate the
360 cameras and lane keeping.
I see that I can do these in forscan.
I see the 360 degree calibration. Is the lane departure warning system camera calibration the same as lane keeping?

Yea, that's the one.

No use. With a CMR not showing i cant get the truck to align. My CMR went offline when I updated the ipma. I'm afraid my dealer won't warranty it because I did my own updates. Does anyone know where this module is located?

Let's let the holiday pass and we'll get you sorted out. Don't worry......whatever it is, we can fix it.

Ok. Even though you're setting the tire size in the BCM, the PCM has a hard-coded maximum value for tire size. That value is less than the value you set in the BCM, hence the PCM complaining about invalid data. You have no choice but to lower the value in the BCM.

I know that a value of 0A7E works. Therefore I suggest you try increasing the value, starting from 0A7E and increasing by 16 each time. You will only need to change the first two characters in 726-15-02. For example, you would try: 7E, then 8E, then 9E, then AE.

Each time you try, you will also try to clear the DTC.
If AE works, you can start going up by 1; so: AF, B0, B1, etc. until you get the DTC and it doesn't clear.
If you get the DTC that won't clear BEFORE reaching any of the "increase by 16" values, you then go up by 1 until the DTC will not clear.

For example, if you try 8E and the DTC won't clear, then try 7F, 80, 81 etc.

This will mean that your speedo will still be off, but it will be off by the minimum possible amount. Your truck's PCM was never meant to have such large tires, so this is the best compromise possible.

Of course, once you have your best value, do the PCM relearn again.

Is this a required step after doing updates in FDRS to upgrade to BC 1.4? I just did my FDRS updates yesterday but did no sort of camera calibration.

 

[Spiffy]

Nothing to do with bc 1.4. Don't worry about calibration. Mine is a issue unrelated to bc

Does anyone know if there is something out there to translate the titles in the spreadsheets. For example, what I have circled.

Message me tomorrow about it.

Will do. Thanks man

ok I think I understand. I’ll try this out step by step. I understand what you are saying though that this size tire was never meant to be. So I will be increasing it not decreasing it?

When I change the tire size I did not do it by changing the value. I did the easy way by tire circumference MM. stock was 2547 Now I have it at 2750 and it’s dead on with GPS.
So do I need to change this back first then start increasing by 16” from there?

And what is the down side by leaving the DTC with a fault? Will it lead to other issues?
Thanks SilverPigeon
