...the ECU and then the process to rest it. I recently tried to get it inspected but the thermostat func code showed up. So I replaced the thermostat and attempted to have it re-inspected but the code still showed up so still no pass...thanks in advance for any help!

Disconnect negative battery terminal and touch wire to positive to drain all capacitors. Give it a few seconds or so and re-connect. If that doesn't work, stop in at an auto parts store and have them read/clear the code for you. Most will as long as you tell them what it was and that you already replaced it.

The ECU doesn't have a simple reset button like a lot of electronics, you have to do the battery trick. Try it and see what happens.
