Solution

1. Preparation

• Ensure the vehicle is parked on a level surface.
• Turn off the ignition and remove the key.
• Gather necessary tools and equipment.

2. Scan for Error Codes

• Tools Required: OBD-II scanner
• Connect the OBD-II scanner to the vehicle's diagnostic port, usually located under the dashboard near the steering column.
• Turn the ignition to the "ON" position without starting the engine.
• Follow the on-screen prompts on the scanner to read and record any error codes.

3. Address Underlying Issues

• If error codes indicate a specific issue (e.g., faulty sensor, misfire, etc.), perform necessary repairs or component replacements according to the manufacturer’s specifications.

4. Clear Error Codes

• With the OBD-II scanner still connected, navigate to the "Erase Codes" or "Clear Codes" function.
• Confirm the action, and the scanner will clear the error codes from the vehicle's memory.

5. Verify Reset

• Turn the ignition off for 10 seconds, then turn it back on.
• Check the scanner to ensure no codes reappear and that the check engine light is off.
