Yes i see why you you couldnt understand that. Spell check did a number on that message. I was basicaly asked if there was anything that could be making the ICM go bad that I shoukd check. I realize its possibke the ICM just went bad but it did work when I installed it. When it gies bad my daughter gets stuck so if there is anything else I can check I would like to do so ahead of time. Worse case now I just let it go and see if the problem comes back. If it does then I will clearly nees to look into more closely.

If I'm not mistaken the grounds for the ICM are through the base and the mounting bolts. Make sure that is good, Bad grounding can be an issue with the modules getting zapped.
