ABS Light, Brake Warning Light & Service Stability Sytem Lights ON - now what??!

A few weeks ago I had a problem with a bad ABS sensor / hub assembly which was setting off my ABS Light and Service Stability System Light. I was told I could still drive the vehicle with those two lights on, while waiting on the exchange hub assembly but with no ABS so the other day, I was going around a sharp bend / curve and suddenly I noticed my Brake warning light comes on and stayed on.

So I was thinking maybe it is the hub assembly causing this - so yesterday I got a chance to put on the new hub assembly / abs sensor to see if this would clear it up. Well, now this is what it does in these steps ...

1. I turn the ignition ON
2. All the warning lights come on and go off as usual - no messages in message center
3. Within 2 seconds or so the ABS Light comes back on and so does the brake light! Right after that the Service Stability Sytem light comes on!

Any ideas what might have happend now guys?
