Hi all,
I just got my truck back from the dealer after taking care of some safety recalls. They replaced the water pump, welded jam nuts on the drag link and (this is the one I'm having trouble with) I guess there was a recall on the "brake transmission shift interlock". The paperwork I got says they flashed the BCM to fix this problem. I now don't have a speedometer or engine brake and the ABS light is on and the No park sensor light is on. I have an MM3 tuner and tunes from Diesel Performance Texas that I bought last year. It's worked good until now. I tried to reflash with my MM3 and custom tunes but that didn't work. Any ideas? I don't think the dealer can flash it back to it's previous state. I knew I shouldn't have taken it in there. Everything was good before.
