Solution
1. Preparation
  • Tools Required: OBD-II scanner, socket set (if disconnecting battery), safety gloves.
  • Safety Warning: Ensure the vehicle is turned off and in park. If disconnecting the battery, wear safety gloves to protect against accidental shocks.
2. Scan for Error Codes
  • Connect the OBD-II scanner to the vehicle's OBD-II port, usually located under the dashboard on the driver's side.
  • Turn the ignition to ON and follow the scanner's prompts to retrieve any error codes.
3. Address Underlying Issues
  • Note any error codes and diagnose the issues. Repair any identified problems (e.g., faulty sensors, leaks).
4. Reset Check Engine Light
  • Disconnect Battery:

    • Use a socket set to loosen the negative battery terminal bolt.
    • Carefully remove the cable and set it aside.
    • Wait for at least 5 minutes to ensure the vehicle’s systems reset.
  • Reconnect Battery:

    • Reattach the negative battery terminal and tighten the bolt securely.
5. Use OBD-II Scanner (Optional)
  • If preferred, use the OBD-II scanner to clear codes by selecting the "Clear Codes" or "Erase Codes" option.
6. Ignition Cycle (Alternative)
  • Turn the ignition switch to the ON position without starting the engine.
  • After a few seconds, turn it back to OFF.
  • Repeat this process three times to reset the check engine light.
