Solution

1. Preparation

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

2. Use an OBD-II Scanner

Connect the OBD-II scanner to the vehicle's diagnostic port 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 prompts to read the error codes. Take note of any codes for reference.
If necessary, clear the codes using the scanner’s option to erase or reset the codes.

3. Disconnect the Battery

Locate the vehicle's battery in the engine compartment.
Use a wrench to loosen the negative battery terminal (black) and remove it from the battery post.
Wait for at least 5 minutes to allow the ECM to reset.
Reconnect the negative battery terminal and tighten it securely.

4. Test Drive

Start the engine and allow it to idle for a few minutes.
Take a short test drive to ensure the check engine light does not reappear.
