My truck seems to be running great, but my diesel mechanic friend ran a diagnostic on it and found the FICM voltage between 46 and 47. He said it is on its way out and I should consider replacing it soon.
Alternator is strong and I just replaced both batteries after he diagnosed it (one battery was bad and was warrantied and I went ahead and replaced the other so it would have 2 new ones!)
Any suggestions? I know this is a pricey repair.
