The power to my laptop was interupted during a full reflash. It didn't shut off but something happened when it switched to battery power. It was to the point where the yellow light had just come on, but I cant get it to do anything. I just get error messages one says not connected to pcm and one says cannot communicate with flashscan. Now my truck is setting in a hotel parking lot. Should I try to find another pcm or is there a procedure to recover it.
