Message: Tried to program the R/T last night when I got it back from the dealer. After programming, the MIL light came on. I unprogrammed and the light stayed on. I disconnected the battery for ten minutes, and the light went away. Then started the truck this morning and the MIL light is on. The only suggestion hypertech had this morning was to send the unit back to them. Meanwhile, I drive around town with the MIL light on. Taking suggestions.....
