Solution

1. Preparation

Ensure you have access to an OBD-II scanner, socket set, and a wrench.
Park the vehicle on a level surface and turn off the engine.
Gather necessary tools and ensure safety protocols are followed.

2. Scan for Error Codes

Connect the OBD-II scanner to the diagnostic port under the dashboard near the steering column.
Turn the ignition key to the "ON" position without starting the engine.
Follow the scanner instructions to read any stored error codes.
Record any codes for reference.

3. Disconnect the Battery

Using a wrench, loosen the bolt on the negative battery terminal.
Carefully remove the negative cable and ensure it does not touch any metal surfaces.
Allow the vehicle to sit for 10-15 minutes to ensure all systems reset.

4. Reconnect the Battery

Reattach the negative battery cable to the terminal and tighten securely.
Ensure there are no loose connections.

5. Check for Codes Again

Reconnect the OBD-II scanner.
Turn the ignition key to the "ON" position and check to see if any codes remain.
If codes are still present, further diagnosis may be required before the check engine light can be reset successfully.
