Toyota puts a preventive service marker on all their cars, this means when brand new they will activate the MIL for engine service just to bring it in to the dealer. Roughly around 50k miles it will do this again.
Try this to reset the ECU, clearing the codes:
1. with the car off, press and hold the mileage reset button.
2. with the reset button HELD, start the car
3. with the reset button still held, you will notice your mileage will mark 5 or 6 dashes ( - ) and they will go disapearing.
( - - - - - )

4. once they have all gone away, release the reset button, and your MIL should be off.
Note: if it is a problem that actually needs attention, it will come back on within 3 - 5 minutes depending on the problem.
Hope this helps guys!
