fans coming on way early?

got in the car today and my service engine light came on and then right after that my fans came on and would not go off. if anyone has an idea on what would make this happen it would be greatly appreciated!

All events that turn on the SES light also cause the fan to turn on and stay on. (I had that same thing happen when the air injection pump seized up and blew it's fuse) You'll need to get it scanned to find what the ECU thinks is wrong.
