F150 Tremor FORScan

Just made both these changes also. Looks good, now have the 50/50 view with a new soft button and finally the awful black box "Full view not available" over the rear camera is gone.

I want to try this but it terrifies me that I’ll screw something up and brick my vehicle.

I’m in Atlanta and I’ll gladly pay someone who truly knows what they’re doing to do it for me.
 
Has anyone used forscan to do the tire mod? Tire Size - requires PCM/TCM Relearn procedure after change (unconfirmed if available in newest FORScan version)

I did it on my 2018 F150 just a few weeks ago when I put on new tires. I did have to do the relearn to clear the check engine light. I do have the latest version (as of a couple weeks ago) and it does have the PCM and TCM relearn available.

OK, I did not do that. I just changed the digits. Any info on the relearning part?
 
You just have to do each one separately. Let them write and download, follow the prompts on screen (key on, key off, key on, etc) and it should be fine.
It did take me doing the TCM twice for some reason before the MIL went away. But it did clear and I got the speedo dead on compared to a GPS app on my phone.

OK, I must have done something wrong. Now reverse break assist no longer available is coming on. ugh. I need to figure out how to revert back and start over. Also, my tire measurements - found on my tire were different than the measurements in the example on the spreadsheet. 35 x 12.5 x 18

As long as you saved your original as built you can load that and revert back to original.
I found a formula on the ForScan forum to get the exact measurements for the tire. I did notice that the formula gave me a slightly different number than what is on the spreadsheet. Not by much, but enough to cause the Speedo to not read correctly.
If you search for tire size formula on that forum, you should be able to find it.

I have not done a tire size on my tremor yet as I’m still running the OE tires.
I did find on my 2018 f150 that doing one change at a time, writing it, and then doing another change was a better way of doing it. Trying multiple changes at once would give me an error or cause another warning to pop up. I did several changes on my tremor one at a time without issue.

It’s under the modules tab if I remember right. Says “PCM (or TCM) relearn”
You click it, go thought the prompts, and that’s it. Pretty easy. Have to do both though and then clear the DTC.

I did save my original build, I don't have to revert all of the changes Do I have to revert all of the changes I made in the past or can I look up the one digit I changed for the tire mod?
 
Can’t really answer that. I have no idea what changes were made to cause the reverse brake assist to show a fault.

Did you try the relearn of the TCM and PCM? That might clear the reverse assist warning.

No, I didn't do the relearning part.
 
I think my issues started when I tried to change the tire size. I want to revert back to the original values. I do have a back up but I don't know how to use it. What can I do in this situation? a couple of things have been turned off include all drive modes but normal.

First, thanks so much for all the hard work that’s put in to letting us do this together trucks. I hit the gambit this morning, GFL, no horn blah blah all the good ones including cameras at speed. Everything took except cameras at speed and I double checked all my entries. Any ideas what I could have goofed along with where I can find the reverse mirror drop! Thanks so much
 
Is there something in forscan to get rid of the "reverse brake aid disabled" screen and "pay attention to surroundings" with the back up camera?

Also is there a way to get your side mirrors to point down when backing? This thread is so big, hard to have time to read it all.

Thanks.

Yes, but there is a caveat. I just did this today.

You can enable Reverse Mirrors in Forscan using just the "simple" programming dialogs. It has to be enabled in BOTH the APIM and IPC modules. Once you do that, reset both modules just in case, and it will appear on your center display in Vehicle settings under Mirrors. Then while in reverse, you use the "mirror select" button to choose one mirror to dip and it will go down, or leave the mirror selected and it will dip automatically when you enter reverse. You NEED the full power seat option with memory recall for this to work as it relies on the memory to return the mirror to its original position.

Here is the caveat. I CANNOT get the mirror to stop going down. It just bottoms out and goes CLUNK CLUNK CLUNK as it overrides its stops. If you deselect the mirror it will return to its original memory position. I don't know if I'm doing something wrong or haven't set it up correctly. I tried using the mirror adjustment switch during its downward travel and the mirror did stop, then when I went back to park it returned to normal, but upon going back into reverse it overran the bottom travel again. Amusingly, the help file directs you to the owner's manual for further info but I didn't get a printed manual with my truck, and the online "clickable" one (which completely sucks IMO) says absolutely nothing about it either.

Coincidentally this is the EXACT same problem I had when I tried enabling this option on my 2016 502A. It's clearly an intended feature since it's right there in the menu, complete with help file, but why it's not working properly I don't understand. It also seems very strange that this would be something Ford has included as an option for at least 7 years but never enabled it, and I refuse to believe it's because they couldn't get the mirror to stop tilting down.

The mirrors on this gen are MUCH smaller than my '16 and I would really like for this feature to work. The 360 camera is great but it's imprecise; I want to see exactly where my rear tire's going when I'm backing up.
