    I agree, thank you all for the help and I am glad to have been able to pass some information back to the community for the future.

    • Drove the truck home, approx 15 miles. At this time, there was no change in error lights or speedometer.
    • Went to reflash the truck with the DRD program but for some reason, the MM3 tuner said there was an SD card error and recommended I reformat it
    • Copied all files off the SD, formatted it FAT32 and copied all files back on
    • Programmed the DRD tune to the truck successfully this time, currently no error light change
    • Went into the MM3 tuner and programmed the tire size from the current setting of 35 to "35" again. As soon as this program completed, the ABS light went away.
    • Checked for DTCs with the MM3 tuner, none present - drove the truck around the block and the speedometer also worked.


    I'm guessing the ECM somehow lost the program and the SD card maybe was corrupt and needed to be reformatted?

    Also a side note, when I went back this morning the Interstate guy said that even though the first battery tested "OK", it definitely had an internal short because it was scalding hot for several hours after it got removed from the truck he said.
    Awesome!

    Glad you got it all resolved.

    New batteries do wonders for our trucks. LOL
