Heads Up display error
My heads-up display displays .11 g's on level ground and not moving.
Is there a way to reset the 'G' reading? I did not find the answer in the big shop manual. All it says is replace the sensor.
If I understand this correctly, the active handling system need to read the correct lateral G force in order to work correctly.
Anybody experience this problem?

I don't think its that. Sitting still, it says .11 g's. While moving, it goes up in a normal manner and goes down as far as zero is gentle curves. But on flat, level ground while not moving, it reads .11 g's.
My concern is the active handling system uses the lateral g's as part of its correction calculation of yaw rate so if the g measurement is wrong, the active handling system won't make the correct correction.
The big GM service manual simply says to check the sensor voltage and if out of spec, replace it. I tried disconnecting the battery in a blind attempt to reset, but it did not work. I was wondering if anyone else had a similar experience.

Someone had a similar problem several months ago - sorry, but I don't remember who or what the solution was. Hopefully they'll see this thread and chime in.

Active handling doesn't use the g-meter. It uses a combination of sensors like yaw sensors, steering wheel position sensors, wheel speed sensors, wheel directional sensors, etc to make the decision of what to do.
I would just reset the g-meter and see what happens.

The fault is not within the HUD, it just displays the value from the EBCM where the senor is connected to.
