I sized up for my toyo 37's and now have a "service trailer brake" in the dtc also a "Parking Assist off". Anything anyone can suggest to help me out? Thanks!

Have someone with a TechII (dealership) reprogram the ABS Module for 285/75/16 tire size...

In the meantime you can set the tire revs per mile to no less than 580 (could be lower, I don't remember exactly-keep going lower until you set a light).

the dealership I went too told me because it's lifted they won't cover it and I have to pay a diagnostic fee

What DTC numbers are you throwing? You can adjust the ECM/TCM to prevent ECM/TCM codes, but if they are coming from the ABS you'll need to go to a dealer - we don't allow programming of the ABS module.

when I scan they aren't in code, They reset everytime I turn the truck on. It's frustrating!
