Try disconnecting the battery for 5-10 minutes. If you had a connector at the clockspring on the steering wheel unplugged when starting it could have caused the light to be thrown. Make sure everything is plugged back in, disconnect batteries, connect again and see if the light is on when the car is started.
I had the same problem on the last 08 corolla when I installed it. Never had the problem when I did my old 01 though.
