Solution
1. Preparation
  • Ensure the vehicle is parked on a level surface and turned off.
  • Gather tools, including an OBD-II scanner, multimeter, and necessary hand tools.
2. Retrieve Diagnostic Codes
  • Connect the OBD-II scanner to the vehicle’s diagnostic port (usually located under the dashboard).
  • Turn the ignition to the "ON" position without starting the engine.
  • Follow the scanner instructions to read and document any error codes.
3. Inspect Electrical System
  • Battery Check:

    • Use a multimeter to measure battery voltage (should be around 12.6V when fully charged).
    • Inspect battery terminals for corrosion and ensure a tight connection.
  • Alternator Check:

    • Start the engine and measure voltage at the battery (should be between 13.5V and 14.5V).
    • If out of range, consider testing or replacing the alternator.
4. Check Fluid Levels
  • Open the hood and check oil, coolant, and brake fluid levels.
  • Top off any low fluids as necessary and check for leaks.
5. Address Faulty Warning Lights
  • Based on the retrieved DTCs, address specific issues:
    • For brake system warnings, inspect brake pads, rotors, and fluid levels.
    • For engine-related warnings, inspect air filters, fuel injectors, and sensors.
