ABS light and traction control light on
Do not know why they came on . But they did at the same time. Did some reading on the situation and some say it could be just some sensors near the wheels. Does any one have pics of these sensors and detail pics of the fixing process? My ACTRON scanner con not read the codes. Made an appointment with the local dealer to check it out. The bill is going to start out at $75 (scanner) and then go up. So is there is away to avoid this, I am all 
Would like to spend my money on mods 
not repairs.. 
Thanks for help.......

I just went throught this too!!! 
Cost me $1600 but I am filing a GOODWILL Repair with GM because I am only 30 days out of warrenty and only have 34000 miles on the car. GM Rep says that my case is under review! Wish me luck.
On the other side of the coin, I had to disect this circuit down to a nats a$$ to get to the bottom of it. I have answered a hand full of post on this very issue. Here are some links to a few post that I responded to; Lots of tips and pictures!

I just figured out that I didnt answer your question! 
Here are some pictures of wheel hubs and speed sensors!

I wanted to test my brakes yesterday, so I pulled maxi fuse # 52 for the ABS circuit. I got warning lights for both ABS and Traction Control. Conclusion: the traction control depends on wheel speed signals from the ABS system. No signals and the traction control shuts down and shows an error. I bet it only takes one faulty speed sensor on one wheel bearing to shut down ABS, then TC is down also. Anybody know how to find a bad wheel speed sensor?

check the codes; I've got the same deal and thanks to Bill and others I've narrowed it down to my left rear sensor. Codes C1234 (LR open/short) and C1227 (LR excessive wheel speed variation) keep popping up daily now after ~ 9-10 miles. Advice also is to get one from Autozone or some other store other than paying a dealer $380, which is what they wanted to bill me plus 2 hours labor @ $125 an hour. If you don't want to/can't do it yourself, you can certainly find a shop that can swap the little bastard out.

i am going to have to dig into this also...i am getting 1225 and 1226 all the time now and i'm 99% certain it isn't the wheel speed sensors...what are the odds that both fail, plus one of them is nearly brand new. I have been fighting this for over a year and yes i have the rear mounted ebtcm

battery
Had battery(red top) checked and charged. Put it back in and no more lights and the car seems to be good. Have not driven more than 2 miles. I will see what happens tomorrow. I understand the code was probably erased when I took the battery out.
The reason I desided to try it was, I was watching the digital read out and seen it drop to 11.5 and return to 12.8 very quickly. Would not of seen it if I had not been watching hard. Thanks for the advice. Hope it is fixed.
