Code C1102

Lately my car has been throwing up this code. It came up a while back when I was in heavy traffic in LA, had to slam on my brakes several times. For a while the check engine light would turn on and off so I figured it was not anything major, but now the light has been solid for several weeks so I am getting a bit worried. I am pretty sure my ABS is not working anymore because my car runs differently than it use to, I cringe every time I have to brake because it takes a lot of force, where as before it would gradually start breaking whenever I took my foot off the petal. I went to a mechanic less than a month ago and my brake pads and rotors were fine. Lately my ECO feature has not been working either. The car does not turn off when I come to a stop, the light just does not come on anymore. What could this code mean? Is there anything I can do to fix this problem myself because a Saturn dealer is no where near me?
