If you disconnected the battery, you need to run the wheel all the way left to right with the ignition on. Otherwise, you might have broken a wheel speed sensor, which will cause several faults.
If you only removed pads and rotors there should have been no change. The speed sensors are right behind the rotors so they are easy to accidentally damage, get the car in the air and look behind them and you will see what I mean. You can even drive up on a curb to quickly get enough room under there to see.
