Service Active Handling
OK, the car has been stored for 6
months w, CETK charger, 40 psi in
tires, Stabil in fuel.
Well, start it up today to bring
the Vette into service, and...........
get 'SERVICE ACTIVE HANDLING"
display in the DIC. Push Traction
control button and it only shows
on or off, no comp mode or all off.
What happened while she was sleeping?

Here is the most complete explanation I have seen. There are a couple of DIY repairs around but you should just take it to the dealer ASAP. It has the potential to be a safety issue when driving.

Thanks, I read Talons post
and he knows what he is talking
about.. This is just a P...er, as I
was ready to drive the car and bring
it out of retirement. It went to bed with
no messages, and woke up 6 months
later with this one.
Anyone else have , or seen of this
HIBERNTATION problem before?
Thanks, Jon

Not that I doubt Talon at all, he's quite knowledgeable!
One other possibility though...
When I put my Vette into hibernation, I take the battery out. I do not leave it connected to the vehicle power harness, nor do I leave it physically under the hood. The point here is BO ELECTRICAL CONNECTION TO THE VEHICLE.
The reason I say this is that some maintenance charges have a high-freq pulse mode that aids in keeping the battery plates clean during non-use. One of the reasons I disconnect the battery from the vehicle is that I don't want high-freq pulses making it to any of my electronics. Yes, the battery acts like a big capacitor, and yes, all modules must pass a CI (Conducted Immunity) EMC tests as well, but I just don't like the idea of high-freq making it to any electronic modules on the vehicles. If it makes it to the modules, then you have to rely on internal filtering in each modules downstream of it's internal power regulating system. As more modules are added to the vehicle, the more the chance that one of them could be damaged due to high-freq pulsing on the power feed.
I am not saying that this is root cause, just wanted to share my thoughts.

Not sure how you had your car stored.. But it couldn't hurt to disconnect the battery and reconnect it.. low voltage conditions can play havoc with electronics sometimes.. I was getting all kinds of false codes when my battery went south.. all was well when it was replaced

ran it for 30 mins, wtith no DIC message.
Today, I staet it and SERVICE ACTIVE HANDILING
