The check engine light serve as a deliver to transmit a signal, sensors of car monitored the emissions system or any other system and communicate with the engine control module directly. When one of these components fails, the computer shows the failure and triggers the check engine light. These failures are called diagnostic trouble codes (DTCs) and should be diagnosed and rectified before attempting to retrieve the light.

You'll need an OBD 2 scanner to help you finish this job.
Firstly, put the diagnostic link connector (DLC) in the Toyota Tacoma car. It is usually under the driver's side dashboard between the steering column and the dashboard. The shape of the connector will match the trapezoidal shape of the plug connection of the OBD 2 scanner.
Connect the plug of the OBD 2 scan tool to the DLC of the Tacoma car. And make sure it is inserted in completely.

Secondly, 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 to the electrical options in the truck without actually launching the engine. It will also supply power to the scan tool from an accessory fuse powered by the battery.

Watch the screen of the OBD 2 scan tool. There are a lot of different models with slightly different functions, but overall, they function similarly. Scroll buttons and "enter" or "select" keys will help you navigate through a few features the scan tool provides. It is recommended to "read codes" first before resetting, in addition to you have already made the necessary repair that triggered the check engine light.

Scroll to the "reset" or "clear” option once the code has been documented, if applicable. Press the "enter” or "select" button to confirm you want to clear the code. Several seconds will pass and the OBD 2 scanner will notice you that the command is being sent to the ECM of the Tacoma car. Once the main menu of the scan tool reappears, the check engine light is reset. Keep in mind that hard codes and even minor codes can re-trigger the check engine light if not modify. Hard codes may re-trigger at once or may have to endure the IM monitor reset of the ECM. This may take a few driving cycles to occur.

Check the status of the check engine light by unplugging the scan tool and then launching the Tacoma. The check engine light should not be illuminated again.
