Autozone can clear it using their generic OBDII scanner, or you can pull the battery cable for 30 minutes, or pending which code it is it may well clear itself once repaired.

If you are going to work on it yourself, ask santa for a simple OBDII scanner; it is the best insurance available that you wont need it.
