Solution

1. Preparation

Gather necessary tools and equipment.
Ensure the vehicle is parked safely and the engine is off.
Have your OBD-II scanner ready.

2. Use OBD-II Scanner

Connect the OBD-II scanner to the vehicle’s OBD-II port, typically located under the dashboard on the driver's side.
Turn the ignition key to the "ON" position without starting the engine.
Follow the scanner's instructions to retrieve and note any error codes.
If necessary, address the issues indicated by the error codes before proceeding.

3. Clear Error Codes

With the OBD-II scanner still connected, navigate to the option to clear or erase codes (this may vary by scanner model).
Confirm the action when prompted, and wait for the confirmation message that codes have been cleared.
Disconnect the OBD-II scanner from the port.

4. Battery Method (Optional)

If the check engine light remains illuminated after clearing codes, turn off the ignition and disconnect the negative terminal of the battery using a socket wrench.
Wait for 10-15 minutes to allow the vehicle’s systems to reset.
Reconnect the negative battery terminal and tighten securely.
