Solution

1. Preparation

Tools Required: OBD-II scanner, wrench set (for battery terminal).
Ensure the vehicle is parked on a flat surface and the engine is off.

2. Scan for Codes

Connect the OBD-II scanner to the OBD-II port (usually located under the dashboard near the driver’s seat).
Turn the ignition key to the "ON" position without starting the engine.
Follow the scanner instructions to read and record any stored error codes.

3. Clear Error Codes

On the scanner menu, navigate to the option to "Erase Codes" or "Clear Codes."
Confirm the action and wait for the scanner to indicate that the codes have been cleared.

4. Battery Disconnect Method (Optional)

Tools Required: Wrench set.
If preferred, disconnect the negative terminal of the battery using a wrench.
Wait for approximately 5-10 minutes to ensure the system resets completely.
Reconnect the negative terminal and ensure it is secure.

5. Verify Reset

Start the vehicle and check if the check engine light is off.
If the light remains illuminated, re-scan for error codes to ensure the issue has been resolved.
