After viewing Mr. Oldham's video in which our longterm 2002 Corvette Z06 flashed up two communiques, I became curious.
Recall that the first message was "Service Active Handling" and the other was "Service Vehicle Soon."
Now, neither of these alerts lit up the check engine light, but perhaps a code or two was stored. So I placed the Z06 into 'diagnostic mode' by threatening to yank off its intake manifold again (actually I followed the instructions here).
It vomited up sixteen 'history' codes (15 of which pertain to 'loss of communication' among the various subsystems) and no 'current' codes. The remaining code (28-TCS C1287 H) for steering sensor rate malfunction mightcouldpossiblymaybe have something to with the "Service Active Handling" message.
My guess: a ground wire is loose somewhere. We'll have it checked out.

Its a traction control system fault, it will freak out when it can't electronically verify your steering angle values. Should probably get that looked at, I doubt it would just be a ground wire that would give you a loss of comm or sensor power failure.

Check "gages" ...spelling error?

The Vette has used this spelling since the C5.

It's a proper variant according to dictionaries. It also fits better. :)

Oh please not another discussion on "gages". No...just no.

You might check the battery as well. My parents had similar issues with a GM vehicle, only to find that the battery had a bad cell in it and that the low voltage was causing numerous electronic gremlins in the car.

Agree with ebuff75. I got a "service column lock" error but with a new battery, it went away and everything is back to working perfectly.
