Solution

1. Preparation

Ensure all repairs have been completed and the underlying issue is resolved.
Gather tools: OBD-II scanner, safety gloves, and safety glasses.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port, typically located under the dashboard near the steering column.
Turn the ignition to the "ON" position without starting the engine.
Follow the scanner’s prompts to read any existing error codes.
If codes are present, ensure they are cleared before proceeding.

3. Disconnect the Battery

Using a socket wrench, disconnect the negative terminal of the battery first to avoid shorting.
Wait for approximately 15-30 minutes to allow the vehicle’s computer to reset.
Optionally, you can press the brake pedal for 10-15 seconds to help discharge any remaining electrical charge.

4. Reconnect the Battery

Reconnect the negative terminal of the battery and tighten it securely.
Ensure all connections are clean and free of corrosion.

5. Perform Drive Cycle

Start the vehicle and allow it to idle for a few minutes.
Take the vehicle for a short drive, ensuring to include various driving conditions (idling, acceleration, cruising).
Monitor the dashboard to confirm if the check engine light remains off.
