Undefined ECU Code

My check engine light just came on after having my 4th starter replaced today, so I'm worried. The code was 0509 which is undefined and not available on the ecu code sticky. Anyone heard of this code? Do I need to recount again? Has my car contracted a wierd previously unheard-of disease?

Thank you.

Use an OBD-II scanner to define the code. $0.00 at autozone last time i checked.
