When the check engine light is on, you open the hood. You check your oil and all your other fluid levels. If they are low, you fill them. You look for a broken wire. You look for a broken hose. If you find the broken or disconnected part, you fix it. If you do not find it, you take the car to the shop. They hook it to a computer. It tells them which part is broken. You get the broken part fixed. The check engine light means something is wrong, fix it.
There is no reset button for the check engine light. You can have Mitz. do it for $$$ or you can remove the negative battery line for a few seconds and replace. That will reset the check engin light.

Have vehicle scanned to determine the problem

Possibly. The check engin light (aka idiot light) is a 'catchall' indicator that something is wrong in the engine compartment, especially since the tranny is hooked up to the engine.
Have vehicle scanned and codes cleared - usually a problem in the emission control system
Take it to Autozone and have them read the check engine error code. That's where you start.
Trouble code P1300 means: Multiple Cylinder Misfire Detected
It is illegal to disable the check engine light.
