"fuel Used" On Dic Not Working

[agrats84]

At every fill-up I reset my trip, mpg, and fuel used. For at least the past two fill-ups I noticed it was 0.0 before I reset it. Driving home I kept it on the display and it still didn't change from 0.0. Everything else is being calculated just fine, except the 'Fuel Used'. I have an '09 5.3L LTZ with a BB tune done back in June. Maybe it has been reading 0.0 since then and I haven't noticed it or it's some other issue I can't figure out. Anyone else have this problem? Any help would be much appreciated.

That's an odd one. I'd try disconnecting the battery to "reboot" the truck.

My 2010 did the same thing, except it would start calculating fuel used when I left. I would go to clear it after pumping, and 50% of the time, it would say 0.0. Never had the forethought to check it half way though a cycle of fuel, but it was annoying.
