I finally got my TM knob and installed it this morning. It all works as advertised. Thanks to everyone on the forum for the explanations and videos. It helped a lot .

Have to say snow mode is a huge difference!
Came to say this as well. It reduces the throttle sensitivity and torque a bunch giving a lot more control on slippery roads. Seems to increase the sensitivity of TCS and ABS as well

Came across the original thread on this and went and ordered mine. Since the OP dealers jacked the prices way up. Took a lot of searching to find one close to what the price originally was. Placed the online order and thought I was all set! Nope! A week later they cancelled order with no communication and returned the money. Second time is a charm right? Went through the exercise again a few weeks ago and just 2 days ago got notice it shipped. I’ll believe it when it’s in my mailbox with the replacement push button upgrade to go with it. Mine is all black now and I will probably dissemble the new one to ditch the chrome with the one I got now. So, looks like Ford is catching on and trying to rain on our aftermarket party ?

I tried to forscan and it still doesn’t work. If Ford did this with the updated pcm, that is wrong. All I can do is try a new TM control in case something happend to it. I don’t want to spend that kind of money and it not work. I wish I new how to test the TM control.
Try putting the old switch back in and then saving a second as built with a different name with your updated PCM.
Disconnect battery for 15 mins; then reboot the truck.

Then try modding the new file (reinstall switch and make changes) and then remember to save it as a different file so you have the updated PCM file as a backup too

Hey guys,

I am new to the forum and recently got a 2019 Ranger Lariat (4x4). This forum is awesome. I cannot stop reading! I am looking into doing this mod as well. My Ranger does not have a locking diff. Would there be any interference if I enable the TM with FORScan? I think someone said early on they are independent, but wanted to confirm.

@Michael Crowe - Have you done any other FORScan modifications? Are they still working? If values are back to default, can you reliably enable other mods? I was wondering if the Terrain Management is the only affected component.

Thank you all for your hard work on figuring out the Terrain Management system.

Other changes work.
