Yesterday fired up the bus and took it for an hour spin. Shut down at Home Depot and when started back up, noticed my Vorad Radar panel showed a fault light...well crap. Had power to the panel, but the radar wasn't working. About 5 minutes later, I noticed the Pro Driver showed "USS Circuit Fault." Pushed menu and the fault code went away.
When I pulled up in my barn and was ready to shut down, the check engine light came on. Shut down and re started. After the re-start, the Vorad worked fine again and no codes or check engine lights.
Any ideas? A short in the making somewhere? Can't find the code in my Pro Driver manual. The Pro Driver stored the two problems in it's menu. This was the first time I had driven the bus since changing out the radiator surge box hoses so I wonder if there was a signal from there buried in the system somehow? Given I also experienced the fault light on the Vorad system though I am thinking something else going on.
