Solution

1. Preparation

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

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port (usually located under the dashboard near the steering wheel).
Turn the ignition to the "ON" position without starting the engine.
Follow the scanner's instructions to retrieve any stored error codes and note them down.

Investigate and repair any identified issues as per the error codes retrieved.
Ensure all repairs are completed to prevent the check engine light from re-illuminating.

With the OBD-II scanner still connected, navigate to the function that allows for clearing or resetting error codes.
Select the option to clear the codes and follow the on-screen prompts.
Confirm that the codes have been successfully cleared.

5. Verify

Disconnect the OBD-II scanner.
Start the engine and check if the check engine light is off.
