ASR Question...
After driving for about an hour, I stopped for gas and when I started my car the "SERVICE ASR" light came on and stayed on. I drove for another half hour or so and stopped to eat. Upon starting the car the second time the "ASR" light came on as usual and then went off and stayed off. Never had a problem with ASR before. Anyone else experience this and do I need to do anything about it? Thanks.
Also, I can run some Carfax's. But this time I am going to have to limit it to five a day. I think that way I won't be red flagged by Carfax. So if you don't get a response immediately, give it a day or two and I'll get it to you. Send me a personal email with your VIN.

Let's say one of the drive wheels loses traction due to slick pavement from rain, snow, loose sand or whatever. The traction control system, operating through the anti-lock brake system, applies the brakes to the spinning wheel giving the wheel with better traction a chance to move the car. If both wheels have poor traction, the system will eventually slow the engine, too, until the wheels regain traction.
By the way, the default setting is for the system to be engaged and you have to switch it off if you want to do a burn out and impress the kids on your block.
As fsr402 correctly suggested, check the brake fluid reservoir. My Corvette did the same thing yours did during an aggressive cornering maneuver.
Turns out the brake fluid was low. I topped it off, kept and eye on it for a week or so to verify there were no leaks and I haven't had my SERVICE ASR lamp snap on sense, knock on plastic....

The ASR and ABS share the same brain(kind of like onedef and Eddie Murphy)
I had a diagram of the whole system somewhere, I'll try to locate it.

I had to add about a tablespoon full of brake fluid. Should I just keep an eye on it or get it into the shop? I did just have new brake pads and rotors put on the back, would that cause a loss in brake fluid? I tell you I know nothing about cars, other than how to clean them. Thanks a lot to all of you and your help.

I would just keep an eye on for a week or so and top off as needed.
It's not unusual to see a slight drop in brake fluid level following service due to settling of tiny air pockets in the system. Don't worry about it. Mine did the same thing and it's been fine ever since...

Has anyone ever had to get service done because it turned out to be more than just low brake fluid.
When I start the vette its goes through usual test of asr growning,then both lights stay on service asr and servive abs.

Thanks guys reading this post left me feeling a little better about the ASR light issue. - I was doing a little road racing this passed weekend (Autobahn Country Club in Joliet, ILL) and had the Service ASR light go on while out on the track. I had the ASR disabled at the time and was a little 
that the Service light went on - came in off the track and shut the car off. Checked the brake fluid and it didn't seem low - turned the car back on (figured it wasn't a major failure) and headed back out onto the track....the light went out and didn't come back on. Just another GM "ghost in the machine"??

My ASR light has been on for about two weeks. It has come on before accompanied by either the service ABS or another ABS light. These two were triggered when I would hit a large bump that shook the car (not hard since it has been lowered). When both were on, I found a loose connection in my front ABS sensor. Since the ASR light has been on, my traction control is null and void.

When my brake fluid got low, my entire DIC lit up like a Christmas tree during an agressive cornering manuever. Definitely let me know something was amiss...
