Solution

1. Preparation

Gather necessary tools: OBD-II scanner, safety gloves, and protective eyewear.
Ensure the vehicle is parked in a safe area with the engine off.

2. Using an OBD-II Scanner

Locate the OBD-II port under the dashboard of the vehicle, usually near the driver's side.
Plug the OBD-II scanner into the port.
Turn the vehicle's ignition to the "ON" position without starting the engine.
Follow the scanner's prompts to read and record any diagnostic trouble codes (DTCs).
If the DTCs indicate no further issues, select the option to "Clear Codes" or "Erase Codes."
Confirm the action when prompted by the scanner.

3. Disconnecting the Battery (Alternative Method)

Using a socket set, disconnect the negative terminal of the battery.
Wait for at least 15 minutes to allow the vehicle's memory to reset.
Reconnect the negative terminal and ensure it is tightened securely.
