I went out to start the truck this morning and nothing happenend. I think the seatbelt light and truck lock looking light came on. The interior lights were flickering a bit. I looked up the codes on the h&s and the first was P0381- glow plug/heater and P1260 Theft Detected/ Engine Disabled. I deleted the codes and tried again another code came up and it was P0579 Cruise Control Multifunction. I know this happened one time before when I was on deployment and my buddy deleted the codes and it started up again after 15 minutes. Anybody have any advice on what to do? The glow plug light doesn't come up at all.
