Before you begin, make sure your vehicle is parked in a safe location with the engine turned off. Put on your parking brake to prevent any accidental movement.

Step 2: Locate the OBD-II Port

The OBD-II port is typically located beneath the dashboard, near the driver’s seat. Once you find it, insert your OBD-II scanner into the port.

Step 3: Connect the OBD-II Scanner

Plug in the OBD-II scanner and turn your vehicle’s ignition to the “On” position without starting the engine. The scanner will power on and communicate with your vehicle’s computer.

Step 4: Read and Clear Codes

Use the scanner to read the diagnostic trouble codes (DTCs) stored in your vehicle’s computer. Take note of these codes as they can provide valuable insights into the underlying issue.

Once you’ve recorded the codes, proceed to clear them using the scanner’s interface.

Step 5: Wait and Start the Engine

After clearing the codes, turn off the ignition and wait for about 10-15 seconds.

Then, start your vehicle’s engine. If the “Service Engine Soon” light doesn’t reappear, you’ve successfully reset it.
