1. Preparation
  • Gather tools: OBD-II scanner, socket set, and safety gloves.
  • Ensure the vehicle is parked on a flat surface and the engine is off.
2. Use OBD-II Scanner
  1. Locate the OBD-II port (typically under the dashboard near the steering column).
  2. Connect the OBD-II scanner to the port.
  3. Turn on the vehicle's ignition without starting the engine.
  4. Follow the scanner's instructions to read and record any trouble codes.
3. Clear Trouble Codes
  1. After addressing any identified issues, navigate to the 'Erase Codes' option on the scanner.
  2. Confirm the action to clear the codes.
  3. Disconnect the scanner from the OBD-II port.
4. Battery Reset (Optional)
  1. Open the hood and locate the battery.
  2. Using a socket set, disconnect the negative (-) terminal first, followed by the positive (+) terminal.
  3. Wait for at least 5 minutes to ensure the ECU resets.
  4. Reconnect the positive (+) terminal first, then the negative (-) terminal.
