You don't have to remove the steering wheel. Just lower the steering column and remove the shrouds. Call your local library and ask if they have either alldata or mitchell on demand shop manuals in digital format. Then print out the instructions. If not, buy a short subscription to alldatadiy.com or eautorepair.net

You have problem with your Rear Anti lock brakes. It has a code in the system. Try reseting the system. Unplug the black box next to the master cylinder for about a minute and plug it back in. Start it back up and see if the brake light is still flashing. If it is I'll post how to check it for codes.
