2017 3500 DRW 4x4. After a year of ABS warning lights coming and going, finally had the ABS pump replaced and cured the problem. At some point in that time frame, I replaced the batteries and also disconnected them to clear the memory of the ABS module to help isolate the problem. At that time the running hours was at about 1200. The idle time running remained the same and did not reset to zero. Is there a way to restore the running time to what it should be, 1600 hours now? Thanks for any input.
