Active Handling - Cruise Disengaged

[MS_Z06]

2004 Z06, (45K) all stock, no codes found in DIC.

When driving in the early morning car cold, weather cold on a flat level freeway the cruise control will not stay engaged. Active Handling message appears and cruise disengages. Later in the day, problem disappears.

Searching past posts reveals possible problem as steering wheel position sensor or cruise pedal switches. The strange thing is no codes of any kind in the DIC and the problem only occurs in the morning when car and weather is colder than in the afternoon.

Are the sensors affected by temperature? What about ground issues.

Thanks

HI there,

I would first adjust your brake pedal switches, as it should be done regularly.

Second, you most likely will need to replace the steering wheel position sensor if you are seeing an "active handling" message.

Active handling warming up, service active handling are different messages and should be understood.

My only question would be WHAT message do you see ????

I just get the "active handling" message, not "service a.h." Occassionally, I'll see the warm-up message at first start up, but I know that's normal.

Thanks for your input.

HI there,
Ok, then that would tell me that you might be having an intermittant problem with the steering wheel position sensor.

"Active Handling" indicates that the system is working to prevent lateral movement of the vehicle that is unintentional.

Normally, when the 2 signals from the steering wheel position sensor do not agree, this can occur.

If the sensor was to fail completely, a code would set, however sometimes when the signals are just slightly off the computer thinks your making an input when you are not.

Thanks again, should I wait until a code is set before taking it in for repair? Seems like this would help tech. determine the best corrective action.

HI there,

Truthfully, this is a safety issue.

I would not wait, but if you can duplicate the problem for the technician, that would be the best course of action.

Simply ask to road test with the technician when he has a Tech2 connected so that he can see the data in the ABS system.

I DO NOT recommend to wait.
