If you reference post #4 theres a picture of it, passenger footwell next to the bcm. There are 2 combs, the one youre looking for has about 8-10 wires on it. The serial wire that communicates with the abs module is the light blue on 5 from the end.

Thanks! Here's a piece of data for you to consider: I had a wet floor early in my ownership of this 2003 C5 (about a year ago). It came from a blocked AC drain. I'm wondering if your car had a similar issue at some point and the wetness might have caused this issue (or at least contributed to it). As I noted earlier, I have a lot of the same codes you have, and I'd sure like to have a functioning ABS and TCS.

Just cleared all of the codes.
So the car had a lot of splices, specifically at c102 next to the battery. The serial data and swps wires were both light blue. Whoever soldered them back together originally did it backwards, i switched them around and zero codes!

Resolution!
Congratulations! Glad you got to the root of the problem.
I'm gonna look at the 'comb' area near my BCM to see if I can find an analogous situation to yours, possibly caused by corrosion in that area.
Since it was useful to you to have a second C5 to help with the troubleshooting, I may just have to buy another vette to go along with my Anniversary Edition convertible to help me solve this problem! (I wonder what the wife will say about that?)
