Anyone know what this light might be? Mine came on when I started to work this morning. Searched for a few minutes before my shift started, but came up empty. Thanks for any help. JC

I redid my search and spelled it right. Found my code listed in the FAQ. JC

What was the cause of the light? What code was it?
