Diagnostic Error after OTA
Had a message yesterday that an update was ready to install (Infotainment). So when I got home I had it do the install.
So now when I go the the Chevy App, it says that there was a diagnostic error because “an attached device may be preventing the diagnostics to complete”….or words to that affect.
Nothing is plugged into the OBD port (ever) but I did have the battery maintainer installed. I unplugged it and reran the App with the same results.
So a coincidence or bug with the OTA. Car seems to be OK other than the diagnostic failure.

Haven’t needed a dealer since delivery 3 months ago, so not sure about how “good” my local dealer really is (and I didn’t buy from them).
They are the largest Corvette dealer in SoCal however……they also had the highest dealer markup as well.
As long as everything works I’ll let it ride until the first scheduled visit for oil change/DCT filter.
