Is there a way to determine or test if the active handling system is working on a 2000 C5. The dealers expert (?) advise was it's working if the light is not on. However, I don't hear the motors running at any time. Thanks in advance for the feedback.

You'll have to push the car hard, take it out in a big empty lot and go at it.

Find a wet spot in the road and hit the gas such as turning while on the gas and wet ground. You'll see the message in the DIC and you should feel it react. Just have extra room available just in case.

Might want to read this.

There is no motor.

Safest way to test is to go to an open parking lot and drive in a circle going faster and faster until the car begins to skid. Then you will know.

Yes, there is a motor. I do agree about the parking lot testing.

Firm, but wet grass works well

No motor involved...

"Active Handling uses a simple yet sophisticated system of sensors to detect unwanted vehicle manuevers. These sensors include a steering angle sensor, yaw-rate sensor, lateral accelerometer and sensors in the vehicle's ABS brake and traction control systems. All of the data that these sensors provide is fed into the Corvette's onboard computer where specially-developed software "reads" all of the inputs and automatically activates the car's brakes selectively to help the driver bring the vehicle back under control."

There is a pump motor that generates brake pressure for the wheel that has a brake being applied to correct yaw. You should be able to hear it run just after you start the car and get up to speed so the ABS system does its self test. Best way to know is working correctly is to set yourself a little slalom course and drive through it fast enough to get the front end plowing as you turn the steering wheel back and forth. When it does this you should feel a rear brake being applied. If you are turning right and the front tires are sliding (understeer) the right rear brake will be applied. If you use the throttle to swing the backend around the outside front brake will be applied to keep the backend from sliding.

Here is a diagram of the hydraulic flow and you can see the motor (3) drives the front and rear brakes even though they are separate.
The active handling option is JL4 and adds the two solenoids to the front brake hydraulics.
