Service Active Handling??
See lots of posts on here about this just popping out of nowhere, cold starts and such...Not my case..
Probably need to scan the codes before anyone can help me but heres the deal:
I took my 03 Z06 out to an empty parking lot and began raping the car profusely. By this I mean that I switched the traction control off and started going ape **** in all directions smoking the tires and having a grand old time...Shortly there after driving away as if I had never done anything out of the ordinary the Service Active Handling appeared and continued to display but disappear only for a split second then return the entire way home.
I am a little disappointed that a "factory race car" is unable to do this without popping codes off but what can I expect, I drive my cars hard. Maybe later when I go to start it this will all be a dream. I doubt it. So anyone else ever encountered this, is it possible i fried a pcm or something or just tripped a harmless code???
Thanks In Advance
Zach

Do this & tell us what you see...
with the key in the on position, but the engine not running
push and release the reset button
next push and release button #4
next push and release button #1 four times
THe car will start cycling thru a series of codes.
when it finishes it return to the first code.
write it down as well write whether it has an H or C after it
you then can use the #2 and #3 buttons to scroll up and down thru the codes list.
write down all the codes displayed and
post them here.
When you are satisfied you have all the codes written down, you can go to each code, push and hold the reset button for 1-2 seconds and each individual code will be erased.
That will help us identify what is causing your DIC warnings
push and release the reset button
next push and release button #4
next push and release button #1 four times

Based on what you told us...you may have had traction control "off", but the Active Handling feature may have been engaged, when you did your burn-outs. So, A/H did not like what was going on...thus, the message. If you have no codes, reseting the Service Active Handling message should clear it out. If this message comes back again on restarting...then it may be your EBCM has decided it's time to call it quits. For a complete tutorial w/pics on that issue, PM me your email address & i'll send you what you need to do, how to replace,or have it repaired .... "hundreds of C5 EBCMs" have been found to be faulty at one point or another... maybe it's your turn. I've had mine.

believe it or not the CODES dont always tell whats going on.
Remember, for AH to warm up, the car needs to idle for 20-30 sec before driving and should be driven straight for the first 20-50 feet. Sounds crazy but this warms up the AH.
Now time to check all your connections. The wires that go into the back of the hub. Some times these loose connection or short. Pull them apart and reconnect them.
Give these a try

Same thing happened to me the other day. Did a couple of donuts in a wet parking lot, had a perma grin on my face, then the "service active handling" message came up.
I have already had my EBCM replaced under goodwill warranty, and hasn't acted up since. I cleared the code via 'reset' button. Upon next startup it said "warming up active handling" and that was it. (3 days ago now)
I think the active handling just gets a little uptight when you start spinning it in circles despite all systems being disabled.

I have an 02 C5 and I discovered that It will throw a "service active handling ABS" message if I start the car with the wheels turned to near full lock, as when parallel parking. If I stop the car and turn it off with the front wheels pointing straight ahead, wait for a minute and re-start, all is fine again. It does not clear unless stopped, turned off and re-started. There must be some problem with AH sensing that something is out of range on start when the wheels are cranked

....."that DIC message"....is normally the message you get, with this senario...it means (what it says)...it takes a few seconds of driving in a straight line, after you leave it parked with the steering wheel turned either way at full lock, for active handling to engage again.

Sounds to me like a bad connection to one of the front wheel speed sensors. When your wheels are at full lock one of the harnesses is probably extended far enough for the connection to fail.
Check for codes ... that will tell you which one is causing the problem .... if you don't know how to display codes ... go here ... then post the codes and someone will tell you what the likely problem is .....

I have a 2004 corvette and the Cruise Control will "drop out" when just driving straight down the highway. I can reset it again right away by just pressing the resume on the turn signal lever. When this happens, I get the "active handling" message on the display. Sometimes it will happen when I press the brakes coming to a stop sign and I feel a slight vibration like when the ABS brakes are working.
Can someone tell me what to do to eliminate this condition ?
Thanks, Jim

First thing to do is pull your codes. Bet you get a C1287/1288 code. one or both means that the SWPS is going out. Same thing happened to my 04. Changed it out and no problem s since. About a $65.00 part.
