Dic codes

I just figured out and decided to check my codes. I had quite a few that came up. They were all "LOSS OF COMMUNICATION" codes with various devices. Should i be alarmed. What causes this? I also just figured out that if I hold the active handling button down it goes into "competitive driving" mode, what exactly is this?

As far as the codes go you will find that the C5 for some reason will throw those codes a lot, I wouldn't worry too much as long as you don't have a "C" code.

Summary of Active Handling System Modes
Three different modes are provided in the Active Handling System:

ON — Active Handling is automatically enabled when the vehicle is started. This is also true of the ABS and Traction Control systems.
OFF — Like Traction Control, the Active Handling System may be manually disabled if the driver so desires. This is not true of the ABS, which is always enabled.
COMPETITIVE DRIVING — In this mode, Active Handling and ABS are both enabled, but Traction Control is disabled.

The "OFF" and "COMPETITIVE DRIVING" modes are important features on a high-performance sports car, as skilled drivers may find that some wheelspin and oversteer can be beneficial to their lap times in competitive events. The Corvette's system allows them to operate the car in this fashion when appropriate, although Chevrolet recommends against selecting these modes for street use. [9]

Did your battery recently go dead? You'd be amazed at how many codes a dead battery will cause.

The loss of communication codes are set when there is a brief and temporary interruption of communication from the various modules to the PCM, unless they have a "C" next to them - which means current, I wouldn't worry too much. Any code with an "H" is a history code.

Bill K. gave a good explanation of Competitive Driving mode - personally, I never shut mine off of the default setting....the computers react much faster than I can and will save my bacon 99% of the time.

Low battery, dead battery and disconnection/reconnection of the battery often result in the loss of communication codes. I'd clear the codes completely and see what if anything comes back. Most likely nothing will show up for a while.

Good explanation of the Competitive Driving Mode....

I printed off all the codes from stengle codes (I think) and keep them and all my CORVETTE info in a three ring binder in clear plastic sleeves. Its a handy way to keep info at my fingertips.
