P0603 code reading. uhh oo

I'm getting the p0603 code on my DTC, How to fix it? My truck is on stock program on the PCM, battery's aren't old. When I got my truck it had a edge evolution programmer on it. Fried PCM?

Stop worrying about it. Are there any symptoms other than the code? The Edge will set the P0603 and so will disconnecting the batteries. If the truck is running well, just smile and be happy with it. And if you want, you can put the Edge back on and drive with the P0603 for the next few hundred thousand miles with no issues. Or you could upgrade to a better chip and live with the P0603 it gave you, but be happier with the performance.
