Hour meter
My 2006 LBZ first reset to zero hours the when the original factory batteries failed and were removed. After that I had to disconnect the batteries several times during repairs and each time it reset to zero hours. Then it started to reset to zero really often for no reason. I posted the problem on TDP and someone responded that there was a GM service bulletin that said to clean and tighten the battery cables to fix the problem. The cables were clean and tight, but I removed them and cleaned and really tightened them. The problem immediately stopped as long as I didn't disconnect the batteries. You would think that was the end of the story but a couple of years later I purchased a used computer from a wrecked 2006 D/A with the exact same p/n and had a Kennedy program installed. Now with the new to me used computer I can disconnect the batteries for weeks and the hour meter does not reset to zero. I am just glad that the truck no longer resets to zero and I hope the problem doesn't return.
The Kennedy program is not likely to have anything to do with the hour meter resetting. It is most likely in the GM programing of the computer. The Kennedy program gave the truck a nice boost in power and a nice increase in fuel mileage. Just my thoughts about the hour meter issue.
