- Keep the scanner connected to the port.
- Navigate to the option for clearing or erasing codes.
- Follow the scanner’s instructions to clear the codes.
And that’s it! The check engine light should turn off. Easy, right? This is super useful because it tells you if the problem is fixed. If the light stays off, you’re good to go. If it comes back on, you might have more work to do.
Using an OBD2 scanner is like having a cheat sheet for your car. It makes diagnosing and fixing problems so much easier. Trust me, once you use one, you’ll wonder how you ever managed without it.

Common Issues And Troubleshooting
Many car owners use an OBD2 scanner to diagnose vehicle issues. Yet, users often face common issues and troubleshooting challenges. Understanding these challenges can help resolve them quickly.
Scanner Connection Problems
Sometimes, the OBD2 scanner won’t connect to the vehicle. First, check the scanner’s power. Ensure the ignition is on. Try plugging the scanner firmly into the port. If it still won’t connect, inspect the OBD2 port for damage or debris. A damaged port may need repair or replacement.
Persistent Trouble Codes
Clearing trouble codes doesn’t always solve the problem. Some codes may reappear after clearing. This indicates an ongoing issue. Check the vehicle’s components for faults. Replace faulty parts and clear the codes again. If the problem persists, seek professional help.

When Not To Clear Codes
Clearing codes with an OBD2 scanner can be useful. But it’s not always the best choice. Sometimes, clearing codes can hide serious problems. It is important to know when not to clear codes.
Identifying Serious Issues
Not all codes are minor. Some indicate serious problems. Your car’s computer sets these codes for a reason. Ignoring them can lead to bigger issues. For instance, a code might show a problem with the engine. Clearing it won’t fix the issue. The problem remains and might get worse.
Always check the code meaning first. Understand the potential causes. This helps you decide if it’s safe to clear the code. If in doubt, do not clear it. Better safe than sorry.
Consulting A Professional Mechanic
Sometimes, you need expert help. A professional mechanic can diagnose the problem. They have tools and experience to find the root cause. Clearing codes without fixing the issue can mislead them. This makes their job harder and can cost you more in the long run.
Consult a mechanic if you’re unsure about a code. They can provide a proper fix. Once the problem is resolved, they can clear the code correctly. This ensures your car runs smoothly.
