Default ABS Module?

I had the following messages pop up in the DIC today, in rapid succession:

SERVICE BRAKE SYSTEM
SERVICE BRAKE ASSIST
SERVICE TRACTION CONTROL

This comes and goes while driving, and resets with every key cycle. The only performance difference is that I have no cruise control. Is this, as I believe, the ABS module? If so, how hard is it to replace?

Did the Brake warning lamp come on at the same time?

Yes, as well as the traction control light. Thought I said that.

Have you checked the brake fluid in the master cylinder. There is a sensor there that can trip those warnings if the fluid level gets too low.

Well, I topped it of as best I could (if there's a min marker, I can't find it, so I went just under the max) last Tuesday, and the problem has not reoccurred. Thanks a lot!
