Can Active Handling be programmed out
2004 CE Convertible
Am wondering if Active Handling can be programmed out. I replaced Steering Wheel Position Sensor a few years ago. Now this one is going bad.
I don't really like what Active Handling does when it's working. I take the old-timey action of steering into a slide. That seems to confuse Active Handling.
If it can be programmed out how is that done?
Thanks for any advice.

Nope, not that I'm aware of (I asked this a few years back when I got my C5).
There used to be a thing called a "LapTrax Controller" that could be wired into the BCM to disable the systems on startup, but they stopped making them years ago.
Laptrax Controller
I was fortunate enough to snag one and it's a blessing. I have mine set to always go directly into "Traction Control Off/Active handling Off" (ABS still active) mode when I crank up. The car does what I want, when I want and it's therefore very predictable (yes, I could get it sideways and probably kill myself in a heartbeat if I so desired).
With that said, my steering wheel position sensor is starting to fail and I still get a warning now and then, it just doesn't upset the vehicle like it used to when the active handling system was enabled (damn car would grab the brakes and yank me on the highway). Like you, I wish there was a way to just fully delete this stuff but we are the minority, most people like being babysit.

To get around the "low trac light", I pulled the gauge cluster and removed the bulb. No bulb = no annoying light

Friend has an 02 coupe. When he got it a couple of years ago EBCM was bad but no Low Trac or ABS lights.. I thought then PO must have removed bulbs.
We fixed EBCM. Later he had the buzzy IPC problem. We installed a used IPC. Still when he turns of Active handling no low trac light.. What do you think PO did to prevent that?

I got to thinking about it, and this guy is making something similar to the old LapTrax module (just not as elegant).
C5 Corvette Button Press Simulator
It gets wired into the button on the console and mimicked pushing the button enough times to turn everything off.

Yup, it's annoying.

But I'm assuming that pressing the traction button just sends a message on the VPW bus, and I'm assuming that a message to the DIC would clear the warning message. Does anyone know if either of those things are true? If we can figure out the details I'll see if I can write the software, and if it works I'll post it on GitHub.

I have a hunch that we could get the same effect with an Arduino that was just wired to power, ground, and the VPW bus, all three of which are conveniently located in the OBD2 connector.

Yes, that part is easy, but then how do you reset the DIC? I'm going to try sending a 'clear codes' message to it but I'm not sure that will be good enough.
But if it does, and if there's a message that will disable AH/TC, then we can do everything we need with just 3 wires and less interior disassembly than the button press simulator.
I'm guessing that pressing the button causes the BCM to send a message to the rest of the modules in the car, and that message is really what turns off the AH/TC features.

If so, the only way I know to do it is to tap the wire from the button behind the gauge cluster (that's how mine does it) as it simulates pushing the button manually. It's not hard, it just takes finishing a wire through the dash. I have no idea if it's possible to send a command over the OBD port to clear the message.
