Having problems with the reflash. I keep getting this message

Battery voltage too low or high
Battery votlage too low or high
Ecm in unknown state

Then the reflash aborts. Truck still runs fine no problems.

I have aftermarket Autometer guages and a kenwood dvd player. Would it cause this problem?
Thinking about taking the fuse out of it but i would like some advice about how to procede.

Any help appreciated.

Took the fuse out and disconnected power to my boost and pyro and still no luck.
Drove it around for about 15 min and still no luck.

Thanks for the suggestions

needs to be on the "run" position as in the position the key returns to after you start the truck
