Activing Handleing Question

[VET RAIN]

I have a 2004 convertible, automatic trans. When driving any speed on a dry road, a slight turn MAY give the sensation you are on ice for about 1 second. The active handleing MAY come on, then go off. I never lose control, just a erie feeling. Anyone else experienced this? :confused

1st off...

...welcome to the ​

I've never had that feeling with my C5 unless I'm breaking em loose.

Nope. The only way to get AH to kick in is to overstress the considerable grip the C5 has on the road. Takes a bit to get it to kick in, youl'd definitly have to try on a dry road.

How are your tires? Are you running stock sizes front/rear (cuz that will kick in AH if you dont have the correct difference in wheel size).

perhaps a sensor issue?

I have Michelin Pilots run flat. I just had my tires balanced and front end adjusted, and filled tires with 32 psi nitrogen.

Read the sticky about pulling codes from the DIC (the text readout above the steering wheel).
How to Pull Codes:
1. Turn your key to the "ON" position, but do not start the engine.
2. Clear any present messages by pressing the RESET button.
3. Hold the OPTIONS button down, and press the FUEL button 4 times. (This will get you into the "codes" section of the DIC.
4. The computer will automatically display all the codes your car has created. It will cycle through each code every 3 seconds. (Have a pen and paper handy to write down the codes)

Note: Any code that ends in an "H" is a history code (something that has occurred in the past, but is not reporting as an error currently.)

5. Once the computer has finished going through all of its codes, press RESET to enter Manual Configuration mode. It should start with a module and show "NO CODES" or "# Codes."
6. To optionally reset codes once in manual mode, press and hold RESET until is displays "NO CODES."
7. Press OPTIONS to go into the next module (ie, from PCM, or Powertrain Control Module, to TCS, or Traction Control System.)
8. Repeat Step 6 until you have reset all the codes in all the computer modules.

Note: Only reset the codes if you want to- it is not necessary to reset them every time you pull the codes.

9. When finished, simply take your key out of the ignition.

How to Interpret Codes
Now, once you've pulled the codes (it will usually be a letter followed by four numbers), you can go to THIS SITE to get an interpretation of what they mean.


Write down the codes and post in this thread.

Someone will be along to tell you whats going on.


(BTW, read that you had the tires balanced and such, do you know if they are stock sizes (17 front 18 rear)?

Barring a mechanical problem, it sounds to me like worn out or overinflated runflats. Is that possible?

I also find it very easy to break the rear end loose on my car on a dry blacktop road (especially if the blacktop is worn down and the surface is mainly small, smooth rocks) and engage the active handling when the front tires are turned. I have to be especially careful when passing on two lane roads. This never happens on concrete where there is a better grip; the car just goes.

However, my car's not stock and it will break the tires loose if I punch it at almost any speed (I'm on almost new GY runflats).

The active handling can be a pain, but turn it off and breaking the tires loose with the front end turned will almost always result in a donut, which is not good in traffic.

The only fix I know of is to restrict your power or get much wider and stickier tires.

Bottom line is that its some combination of your tires or certain roads.
