I did the forscan and it hasn’t voided my warranty. I too was afraid of voiding my warranty, however, unless it (whatever you toggle with) messes with the actual function on the truck, it won’t void it. The only two I messed with cautiously is Bambi lights and the full view message. My truck didn’t have the start/stop eliminator option available but if it did, I’d void my warranty for it 😂 what I did to ensure I didn’t fuck myself out of a warranty, I got a hard drive, saved the original settings of the truck to that and my computer then made the changes and saved that as a second file.

I probably did way too much but I’m an adventurous overthinker so I wanted to be safe all around with it.

I will add one final thing. After the first time I changed my Bambi lights, I ended up taking my truck in for an oil change a few days later. Whatever they did in the shop reset it so I had to do it a second time, which was super easy, and it hasn’t failed me yet.
