I hope some one can help me. I have a F350 2008 6.4. I Recalibrated the PCM with my IDS everything whent fine. Then it tells me to Recalibrate the IC to but my IDS said there was no new Calibrations for it at this time. Then after that I could not start the truck. Then I got a P1260 code. I cleared it and tryed reprogram the keys. That didn't work and Now I have a B1213 code as well. the theft light will either stay on or flash the 21 code. I have purched two new keys and tryed reprograming them as well but still no luck. I checked all fuese and they are good. I then went back and did the AS BUILT DATA and started with the PCM and IC. And still no luck. I have been told It might be the IC bad and have to replace the dash. Does anyone have any ideas or have I done something wrong with it? Truck ran great before I recalibrated it. Just it wasnt getting very good milage and was told to recalibrate it and that it would help.
