Ways to Reset the Check Engine Light on a Toyota Tacoma

    1

    Locate the diagnostic link connector (DLC) within the Toyota Tacoma. It's under the driver's side dashboard amongst the steering column along with the dash . The shape of your connector will match the trapezoidal shape on the plug connection on the OBD II scan tool.
    2

    Attach the plug with the OBD II scan tool towards the DLC from the Tacoma. Make sure it truly is plugged in thoroughly.

    Place the ignition key into the Tacoma and turn it two clicks to activate the "key-on/engine-off" mode. This mode illuminates the dash and activates the power towards the electrical options in the truck without actually starting the engine. It will also provide power to the scan tool from an accessory fuse powered by the battery.

    Read the screen with the OBD II scan tool. There are many different kinds with slightly different options, but overall, they function similarly. Scroll buttons and "enter" or "select" keys will help you navigate through the several features the scan tool offers. It is recommended to "read codes" first before resetting, unless you have already made the necessary repair that triggered the examine engine light.

    Scroll towards the "reset" or "erase code" option once the code(s) have been documented, if applicable. Press the "enter"or "select" button to confirm you want to erase the code(s). A few seconds will pass and the OBD II scanner will alert you that the command is being sent to the ECM on the Tacoma. Once the main menu from the scan tool reappears, the examine engine light is reset. Be aware that hard codes and even minor codes can and will re-trigger the examine engine light if not rectified. Hard codes may re-trigger immediately or may have to endure the IM monitor reset from the ECM. This may take several driving cycles to occur.

    Check the status on the check engine light by unplugging the and then starting the Tacoma. The check engine light should not be illuminated as long as a hard code is not re-triggering the faulty device.
