hi all, new to this stuff so bear w/ me. ive done a search and couldnt find a problem simmilar to mine. just bought the car a couple weeks ago (98 coupe) the active handeling used to come on and off at will. sometimes constantly! when it was on i could use the button to turn it off. when it was off i could use the button to turn it on it just wouldnt stay there for long. now the button doesnt do anything, but the good news is it quit switching itself back and forth. but it is stuck on. any help is greatly appreciated.

If you press the button and hold it down for about 3-4 seconds you'll put the car in "Competition Mode".......this means that your Traction Control is off, but your Active Handling remains on. To undo, simply press and hold the button again and the car should return to both systems being "on"
If I read your post correctly it sounds like the system is changing by itself while the car is running? If so, that's a whole nother issue. However, it doesn't matter what mode you have the car in but once you turn the car off and then re-start it and will always default back to T/C on and Active Handling on. You would have to manually press the button to change the setting after each start up to turn either system off. Not sure if this helps?

I'm interested in this too! I can't turn it off after my engine swap, the traction (on) and active handling (on) warning lights just stay on! I can't do a burnout from a dead stop!!!!! The pcm just retards my timing!!!! I can't seem to find a wire or plug that I have left undone or damaged!

Do you have any codes showing on the DIC when you run the On Board Diagnostic system? From the schematic it looks like the button feeds the BCM. The button is a momentary switch to ground of an input to the BCM at D15 C2. Once your finger leaves the button the switch is open. When the switch is open the input line is pulled to 12 Volts through a resistor in the BCM. You should be able to see this 12 volts on the Brn/Wht wire connected to the switch. When you push the switch it should go to zero.

Active Handling
I just bought my 99 Vette yesterday! It gets delivered Monday. I was told that the Active handling issue was a common problem on the C5. The display continually shows Active Handling Warming… it doesn't even turn on. The previous owner said there was a common ground problem. His explanation was that if I find the common ground it will fix most of the problems, including the Passenger window issue.
I’m looking for help also!

had a similar problem in mine, thread here http://forums.corvetteforum.com/show....php?t=1092720
I'd be driving down the highway in a straight line, AH would come on and off, with right or left brakes deploying. very scary to have your car tug right or left at highway speeds. took 6 trips to the dealer, turned out to be the steering wheel position sensor, but never threw a code. I just had the luck of finding a tech who had seen the gremlin before

Since you are not throwing the C1283, steering wheel sensor, your problem is the ground. On the 1997-98 models, there is a left rear ground by the exhaust that is very sensitive and some others near the engine. Search for grounds and there is a diagram of all the grounds in the c5 and several topics on locating and cleaning them...most of the issues with electronics not working right are associated with bad grounds.
