Solution
1. Preparation
  • Gather necessary tools: OBD-II scanner, multimeter, basic hand tools (socket set, screwdriver).
  • Ensure the vehicle is parked on a level surface with the engine off.
2. Scan for Error 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 retrieve and record any error codes.
3. Address Identified Issues
  • If error codes indicate specific components (e.g., oxygen sensor, brake system), proceed to diagnose and repair these individual components.
  • For example, if a code indicates a faulty oxygen sensor:
    • Disconnect the battery before working on electrical systems.
    • Remove the faulty sensor using a socket wrench and replace it with a new one.
    • Reconnect the battery and clear the error codes with the scanner.
4. Fluid Checks and Top-ups
  • Open the hood and check engine oil, coolant, brake fluid, and transmission fluid levels.
  • Top up any low fluids with the appropriate type as specified in the owner’s manual.
5. Visual Inspection
  • Inspect battery terminals for corrosion; clean with a wire brush if necessary.
  • Ensure all doors, trunk, and hood are fully closed to reset any related sensors.
