Welcome to 2CarPros.
The B1304 indicates the accessory delay relay has a short to power. This relay allows power to continue to things like the power windows. It will provide power for up to 10 minutes or until the door is opened. I'm not sure how that ties into the work you did.
As far as the C1B00 that deals with the steering angle sensor. Make sure everything is properly plugged in and connections are clean and tight. Chances are it needs re-calibrated. Here are the directions. It does require a special tooling (scanner).
