Solution

1. Preparation

Gather necessary tools: OBD-II scanner, socket set, and safety gloves.
Ensure the vehicle is parked on a level surface and the engine is turned off.

2. Use OBD-II Scanner

Plug the OBD-II scanner into the vehicle’s OBD-II port (usually located under the dashboard near the driver's side).
Turn the ignition to the "On" position without starting the engine.
Follow the scanner's prompts to read and record any trouble codes present.

3. Clear Error Codes

On the OBD-II scanner, select the option to erase or clear trouble codes.
Confirm the action when prompted and wait for the scanner to indicate that the codes have been successfully cleared.

4. Battery Disconnect Method (Optional)

If you prefer to reset the check engine light manually, disconnect the negative terminal of the battery using a socket set.
- Sub-steps:
  - Use the appropriate size socket to loosen the bolt on the negative terminal.
  - Remove the terminal and ensure it does not touch any metal parts.
  - Wait for at least 15 minutes to allow the vehicle's computer to reset.
  - Reattach the negative terminal and tighten the bolt securely.
