My tow rig threw a code, which isn't uncommon. I usually plug in my OBDII reader and make sure it's not something worrisome, clear it, and forget about it.
Today, my OBDII reader isn't connecting to the truck at all. Have verified that it still works by connecting to the always reliable Honda odyssey, and no issues, so I think this is a truck thing.
Truck is 2010 Chev Silverado 2500 6.0L gas engine, if any of that matters.
Thoughts? I'm not too worried because truck is running great as usual. But eventually I'll need that code cleared.
