Need to adjust tire size, and ABS option missing on my Smart Touch!

[bigceltic]

I went to change my tire size (put my 20" wheels back on after towing season) on my Smarty Touch and the screen only shows DTC and ECM.. it used to also say ABS. The only change to it has been I sent it in for a new screen a few months ago.

Do I need to update the SW or something? Very strange.

If unable to fix it, does AlphaOBD allow me to change tire size?

Help! I need my truck in the morning.

Thanks!

Yes, AlfaOBD does let you change the tire sizes.

I am going to try to do a complete SW update on the touch and see if that brings the ABS option back.

Ugh, update Feb. 16, 2024 won't take. Keeps failing. Trying the orig update.
Nope. too old. Trying the newest one again

Ok, went back to basics and refomatted the SD card, loaded the new firmware ver on it, then recopied my ECM directory and voila! Firmware update worked.

However, no ABS option. Is this somehow related to the fact that I returned the truck to stock? Do I need to set a program?


UPDATE: Well heckfire... I programmed it to SW 1 and the ABS option showed up! Tomorrow after work I will try resetting to stock and see if it goes away again! Frustrating and panic inducing! ;-) I need a barley pop!

Thanks, @Diesel85 for your help!
