Solution

1. Preparation

Gather necessary tools: OBD-II scanner, vehicle owner’s manual.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the battery if further inspection or repairs are needed to avoid electrical shorts.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's OBD port (usually located under the dashboard near the driver's seat).
Turn the ignition to the "On" position without starting the engine.
Follow the scanner prompts to retrieve and record the trouble codes.

3. Address Identified Issues

Based on the trouble codes retrieved, perform necessary repairs (e.g., replacing a faulty sensor, fixing a vacuum leak).
Ensure all repairs are completed before proceeding to clear the codes.

4. Clear the Codes

With the OBD-II scanner still connected, navigate to the “Erase Codes” or “Clear Codes” option in the scanner menu.
Confirm the action to clear all stored trouble codes.

5. Test the Vehicle

Start the engine and allow it to idle for a few minutes.
Take the vehicle for a short drive (10-15 minutes) to ensure the Check Engine Light does not reappear.
Monitor vehicle performance during the drive.
