Definition: "Active Handling Warming Up"
There have been so many posts on this that I had to find out what GM was up to with this message.
The below is true of all vehicles with stability control, but most don't bother with the message.
FYI: The normal industry standard is a response time of 100-150ms (millisecond) with a maximum response time of 300ms at -20 F. This is with both DOT 3 and DOT 4 fluids.
You also want the ICU ("ABS module") as close to the master cylinder as possible.
In other words, GM lawyer inspired Nannying.

During the 1998 model year, just prior to production of cars with the Active Handling option, the Corvette's ABS brake hydraulic control unit was relocated to the front of the engine compartment to facilitate quicker Active Handling system "warm-up" and shorten front brake response time when the brake fluid is cold.
In temperatures below 14oF, the Corvette's Driver Information Center (DIC) will display an "Active Handling Warming Up" message as soon as the vehicle reaches 6-mph. That's a caution to the driver that Active Handling is not fully-functional yet. As soon as the system warms up, another message "Active Handling Warmed Up" will be sent to the driver via the DIC.

Nobody ever said it worked correctly, just how it's supposed to work.
