Allison 5sp: Truck throwing a Co 205 code

[danzigfan2002]

I rebuilt my trans and done my pump rub this weekend.
Now after you drive the truck it throws a co205 code and the brake and anti lock lights come as well as the service brakes soon. Just wonder if anybody has come across this, or if i could get any input.

That's: C0205 ABS enable relay contact circuit open.

I did some forum searching (this and others) and couldn't really find anything Duramax Specific..

Could be a disconnected wire.
