Reset camera by removing battery completely for about 10 seconds.
otherwise, time for service.
sounds like a processor board issue.
you can use a contact cleaner sparingly, available from frys electronics or any other electronic reseller like radio shack.
good luck

Busy and or Error 01

For error message 01 the manual says: Communications between the camera and lens is faulty. Clean lens contacts.
Solve: Clean the electrical contacts on the camera and lens and use a Canon lens.
SO if you are using a different lens or a non Canon lens this could be what is wrong.

If you never changed a lens, it still can be that something went wrong in the communication between the camera and lens. Just careful remove the lens and with a dry and lint free cloth, clean all contacts on the lens and in the camera. While working on the lens, close the camera with the camera cap, or put the camera face down.
Don't use anything sharp while working on a lens or a camera.

My Canon EOS Rebel XS only takes pictures indoors (ERR. 01)

You didn't say which shooting mode you're using, but I'd bet you're in Manual mode and have dialed in a completely wrong aperture/shutter speed combination for bright lighting conditions. For example, 1/60th of a second and f2.8 in bright sunlight would be "burning out" your image, so the camera may be giving you an error message. Try using AUTO or PROG setting and see if the problem persists. If it does, try a different lens. You may have an incompatible mount, or one of the contacts may be damaged. If all else fails, try your lens on another Canon camera.

So, have you cleaned the contacts as you were advised? You do this by removing the lens and cleaning the contacts on the camera body and on the lens where they meet with a cotton swab lightly dampened with rubbing alcohol.

Error 99 comes while taking photographs

This could well be a serious issue, which you'd need to send to your manufacturer to fix, however there are a few things you could try first:

Take your lens off and with a clean rubber (like on the end of a pencil), clean the contacts of both the camera and the lens.
