Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off and the keys removed from the ignition.

Tools Required:

OBD-II scanner
Socket set
Torque wrench (if needed for repairs)

2. Scan for Trouble Codes

Connect the OBD-II scanner to the vehicle's diagnostic port, located under the dashboard near the driver's seat.
Turn the ignition key to the "ON" position without starting the engine.
Follow the scanner’s instructions to read and record any stored trouble codes.

3. Clear the Codes

Using the OBD-II scanner, navigate to the function for clearing trouble codes.
Follow the prompts on the scanner to erase the codes from the vehicle's computer.
Confirm that the codes have been cleared successfully.

4. Test Drive the Vehicle

Start the engine and allow it to reach operating temperature.
Take the vehicle for a short drive to ensure that the check engine light does not reappear.

5. Monitor for Recurrence

After the test drive, check the dashboard to confirm that the check engine light remains off.
If the light reappears, further diagnostic and repair work will be necessary.
