Most likely it is nothing to worry about. The ECM will throw an engine light after a short. It's just alerting you to the short (which you already know about but which is now fixed). If that's all it is then the engine light will go out after a fixed number of re-starts. I can't remember the exact number (maybe 10) and I can't refer to the service manual as I'm at work.
Cheers, Richard
