"LTPWS" => Low Tire Pressure Warning System.
It's a nifty safety feature and no C5 Corvette should be without it!
Since I had my '02 Z06 PCM update (iaw TSB #02-06-04-010) to address the Erratic Fuel Gauge behavior, I have yet to experience this problem. Keep in mind it's only been a couple months and not that many tankfuls of gas since I had the reflash. I'm not yet prepared to say that merely a reflash is necessarily a guaranteed fix. But so far, so good.
