Can they be accessed through the DIC? They are wanting to start doing our oil changes off of hrs instead of miles since our trucks idle so much. Since they are base models, they don't have a DIC, only the button on the instrument cluster. I was wondering if anyone has added the DIC from LMC Truck and will it show hrs? A guy I work with added one to his gasser and it does. They took one of our trucks to a dealership and hooked it to a scan tool and said it wouldn't show engine hrs. I was planning on getting a DIC anyway, but if Halliburton will buy, it will be even better.:woott:
