Diy genius: how to reset the maintenance light on your 4runner in minutes

The maintenance light on your 2018 Toyota 4Runner serves as a reminder to schedule regular maintenance to ensure optimal performance and longevity. However, once maintenance has been performed, you’ll need to reset the light to avoid unnecessary reminders. This blog post provides a step-by-step guide on how to reset the 2018 Toyota 4Runner maintenance light.

Step 1: Gather Necessary Materials

Before starting the reset process, ensure you have the following materials:

• 4Runner owner’s manual
• Flathead screwdriver or key

Step 2: Locate the OBD-II Port

Open the driver’s side door and locate the OBD-II port under the dashboard, usually near the steering wheel.

Step 3: Insert the Jumper Wire

Using a small flathead screwdriver or key, insert it into the OBD-II port and locate the following terminals:

• Terminal 4 (CG)
• Terminal 13 (TC)

Step 4: Connect the Jumper Wire

Connect the jumper wire between terminals 4 and 13. This will create a connection between the two terminals.

Step 5: Turn the Ignition On

Turn the ignition key to the “ON” position but do not start the engine.

Step 6: Wait for the Maintenance Light to Blink

After a few seconds, the maintenance light on the dashboard will start blinking.

Step 7: Disconnect the Jumper Wire

Once the maintenance light begins blinking, disconnect the jumper wire from the OBD-II port.

Step 8: Turn the Ignition Off

Turn the ignition key to the “OFF” position.

Step 9: Start the Engine

Start the engine to verify that the maintenance light has been successfully reset.

Additional Notes:

• If the maintenance light does not blink after connecting the jumper wire, ensure that the jumper wire is creating proper contact with the terminals.
• If the maintenance light remains illuminated after following these steps, consult your Toyota dealer for further assistance.
• Resetting the maintenance light will not affect the vehicle’s maintenance schedule. It is still recommended to follow the recommended maintenance intervals as outlined in your owner’s manual.

Troubleshooting:

• Maintenance light still blinking: Ensure the jumper wire is securely connected to terminals 4 and 13. If the light persists, consult a Toyota dealer.
• Maintenance light not blinking: Verify that the ignition key is in the “ON” position but the engine is not running. If the light still does not blink, check the jumper wire and terminals for proper contact.
