DIC information center

Is there a way to reprogram the dic on a 2013 GMC 3500. The numbers when you scroll thru always seem to be wrong. Like the amount of fuel remaining, and the distance traveled, and the mpg. even the speed is off my GPS gives me speed and my dic always says a lower speed than what my gps tells me.....

    Are the tires the correct size or did the dealer or you add upgraded wheels or tires. Sounds like the calibration is affected by tire/wheel size.

    You'll need a dealer or mechanic to re-calibrate the parameters.
