Solution

1. Preparation

Tools Required: OBD-II scanner
Ensure the vehicle is parked in a safe location with the engine off.
Have the OBD-II scanner ready for use.

2. Connect the OBD-II Scanner

Locate the OBD-II port, which is typically found under the dashboard near the driver's side.
Plug in the OBD-II scanner until it clicks into place.

3. Turn on the Ignition

Turn the vehicle's ignition to the "ON" position without starting the engine. This powers the OBD-II scanner.

4. Read and Clear Codes

Follow the on-screen prompts on the OBD-II scanner:
1. Select "Read Codes" to view any stored trouble codes.
2. If no issues are present or after repairs, select "Clear Codes" or "Erase Codes" to reset the Check Engine light.
Confirm the action when prompted by the scanner.

5. Disconnect the OBD-II Scanner

Once the codes have been cleared, safely unplug the OBD-II scanner from the port.

6. Verify the Reset

Start the engine and check if the Check Engine light remains off.
Allow the vehicle to run for a few minutes to ensure the light does not reappear.
