You can reset the check engine light on your 2008 Toyota Tundra just using an OBD II scan tool. This tool can be purchased from your local auto parts retailer. The Tundra comes equipped with an On-Board Diagnostic Second Edition computer that monitors all of the electrical and mechanical functions of the vehicle. Diagnostic trouble codes (DTCs) are sent from sensors positioned throughout the Tundra to the OBD II computer whenever they detect a problem in one of the vehicle's systems.

Find the diagnostic link connector (DLC) on the driver's dashboard above the steering column. You will know you have located the correct port by examining the size and shape of it and comparing it to the size and shape of the OBD II scan tool's connective cable. It should be trapezoidal in shape.
2Plug the OBD II scan tool into the diagnostic link connector (DLC) of the Tundra. Don't force the tool into the port because doing so could bend the pins inside.
3Put the key into the ignition and turn it to the "on" position. Don't let the engine start, however. The "on" position turns on the electrical systems of the vehicle and powers on the OBD scan tool.
4Look at the OBD II scan tool's screen. Use the arrow keys to scroll to the "erase code" or "reset" command. Press "select" or "enter" to select the erase option. Wait for the main menu of the scan tool to appear.
5Turn off the vehicle and unplug the scan tool from the port. Wait one minute and then turn on the engine. Look at the instrument panel to verify that the check engine light has shut off.
