I have a 1999.5 Ram 2500 4c4 24V Cummins with 357700 miles, was driving and noticed abs and brake light were on. Went further and lost speedometer and odometer. About 10 miles later fuel gauge was resting on empty (I have roughly a half tank left) other forums point to the abs sensor being out which I replaced only 1000 miles ago (2 weeks) and the output shaft speed sensor as well. No codes when checked with the tuner. Truck still runs, drives and stops fine but I hate idiot lights on the dash. All help would be appreciated. Don’t want to take to a shop as I’m on a budget.

 

Will you scanner read live data? If so, see if the PCM is getting anything for vehicle speed. Gas gauge is going to be a separate issue. It is completely independent of everything else.
