Gather necessary tools and parts.
Disconnect the battery to ensure safety.
Allow the vehicle to cool down if it has been running.

2. Identify and Address Warning Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Retrieve and document any error codes.
Refer to the vehicle’s service manual to understand the specific codes and their implications.

3. Inspect and Replace Components (as needed)

Based on the error codes:
- For engine-related codes: Check and replace faulty sensors (e.g., O2 sensor, MAF sensor) as indicated.
- For brake system codes: Inspect brake fluid level and brake pads; replace any worn components.
- For battery codes: Test and replace the battery if it shows low voltage or failure.

4. Clear Error Codes

After repairs, use the OBD-II scanner to clear all error codes from the vehicle's computer.
Reconnect the battery.

5. Final Check

Start the engine and monitor for any persistent warning lights.
Conduct a short test drive to ensure all systems are functioning properly.
