Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the battery to ensure safety during repairs.
  • Allow the engine to cool if it has recently been running.
2. Scan for Error Codes
  • Connect the OBD-II scanner to the vehicle's diagnostic port.
  • Turn the ignition to the ON position without starting the engine.
  • Record any error codes displayed and refer to a service manual for code definitions.
3. Inspect Gas Cap
  • Remove the gas cap and inspect for cracks or damage.
  • Clean the sealing surface on the filler neck.
  • Reinstall the gas cap, ensuring it clicks securely.
4. Check Fluid Levels
  • Open the hood and check engine oil level using the dipstick; add oil if necessary.
  • Inspect the coolant reservoir and top off with the recommended coolant type if low.
5. Visual Inspection of Components
  • Look for any frayed or cracked hoses, especially vacuum lines.
  • Check the condition of belts for signs of wear.
  • Inspect electrical connectors for corrosion or damage.
6. Battery and Electrical System Check
  • Use a multimeter to measure battery voltage; it should read around 12.6 volts.
  • Ensure all battery connections are tight and free from corrosion.
7. Clear Codes and Test Drive
  • If repairs were made, use the OBD-II scanner to clear the codes.
  • Start the engine and take the vehicle for a test drive to see if the check engine light returns.
