Service charging system.....
Basically, a really mean OVERREV will cause the alternator to fail.
Some of the time it can happen that the alternator outright fails to charge and then you're replacing it.
Most of the time, if it continues to charge, you can simply turn off the "L-terminal" code that sets and the message on the DIC goes away...I've done this with cars 2 and 3 years ago and they're still fine to this day.
That's all it is....Just make sure it's charging.

I had the same message due to low battery but a couple weeks later I took it in for service and ended up with a new alternator. Originally I was told they had to check the computer and that some cars have had a problem if they had hit the rev limiter.

This happens to be a problem for a lot of folks, especially those with underdrive pulleys. Many people have been hosed into replacing the alternator when it wasn't necessary. Here area couple options:
1) edit the software settings to not trip the alarm at the lower values...BUT we drive a performance auto and for those of us with tuned cars it is NOT a good idea to do this--hell even if you're car is stock don't do this. Fuel Pumps, injector cycles, and various other aspects of the car that are voltage controlled need the right voltage to avoid lean conditions, detonation, engine damage, etc. I advise AGAINST this. Sorry, just my .02
2) Lose the underdrive pulley and post it in the For Sale section. It's not giving you that much HP. Opt for an electric water pump to make up the difference.
3) Edit the software to have the error code for this completely removed...not my recommended solution.
4) Do what I did through my tuner...Cartek...swap out the alternator pulley to spin it into the right range to give the appropriate voltage so everything is happy!!! Cost about $100 bucks!!!
Just my .02, not an expert but I've live this one.
