What OBD2 Scanner Can Clear Codes: A Comprehensive Guide

When your car’s “Check Engine” light turns on, it can be a stressful experience. You might be wondering what’s wrong with your vehicle, and how much it’s going to cost to fix. Fortunately, an OBD2 scanner can help you diagnose the problem and even clear the codes, potentially saving you time and money. But not all OBD2 scanners are created equal. Some can only read and clear codes, while others offer more advanced features like live data readings and even reprogramming capabilities.

In this guide, we’ll explore the different types of OBD2 scanners, their features, and how to choose the right one for your needs. We’ll also answer the question: can all OBD2 scanners clear codes?

What is an OBD2 Scanner?

OBD2, short for On-Board Diagnostics II, is a standardized system used in vehicles manufactured since 1996. It allows you to access diagnostic information stored in your car’s computer, including fault codes that indicate problems with your vehicle’s engine, transmission, and other systems.

An OBD2 scanner is a device that plugs into the OBD2 port located under your car’s dashboard, typically near the steering column. It then communicates with the car’s computer to read and interpret these diagnostic codes.

What OBD2 Scanner Can Clear Codes?

While most OBD2 scanners can read codes, not all of them can clear them. Here’s a breakdown:

Basic OBD2 Scanners: These are the most affordable and simplest type of scanner. They can read codes and display them on their screen, but they often lack the ability to clear codes. This is because they don’t have the necessary software or communication protocols to interact with the car’s computer to clear the codes.

Advanced OBD2 Scanners: These scanners are equipped with more advanced software and communication capabilities. They can read, clear, and reset codes, as well as perform other functions like reading live data, resetting service lights, and even reprogramming certain vehicle systems.

Professional-Grade OBD2 Scanners: These scanners are designed for professional mechanics and automotive technicians. They have the most advanced features and can perform complex diagnostics, such as reprogramming engine control modules (ECMs), calibrating sensors, and troubleshooting electrical circuits.

How to Clear Codes Using an OBD2 Scanner

Here’s how to clear codes using an OBD2 scanner capable of doing so:

Plug the scanner into the OBD2 port. This is usually located under the dashboard, near the steering column.
Turn the ignition key to the “ON” position. You may need to turn the key a second time to access the scanner’s menu.
Select the “Clear Codes” option. This option may be labeled differently depending on the scanner you’re using.
Confirm the code clearing process. Some scanners will prompt you to confirm the code clearing process.
Turn the ignition key off and back on. This will reset the car’s computer and clear the codes.
Check if the “Check Engine” light turns off. The light may remain on for a short period before turning off.

Tips for Choosing the Right OBD2 Scanner

Here are some factors to consider when choosing an OBD2 scanner:

Your budget: Basic OBD2 scanners are very affordable, while advanced scanners can be more expensive.
Your needs: If you only need to read and clear codes, a basic scanner may suffice. However, if you want more advanced features, you’ll need to invest in a more sophisticated model.
Compatibility: Ensure the scanner is compatible with your car’s make and model.
Features: Consider the features that are most important to you, such as live data reading, service light resetting, and reprogramming capabilities.
Ease of use: Choose a scanner with an intuitive interface and clear instructions.

What to Do After Clearing Codes

After you’ve cleared the codes, it’s important to drive the car for a few days to allow the car’s computer to monitor for any further issues. If the “Check Engine” light comes back on, it means the problem hasn’t been resolved and you’ll need to take your car to a mechanic for further diagnosis.

“Clearing codes without addressing the underlying problem is like putting a Band-Aid on a broken leg,” says Dr. Michael Evans, a renowned automotive engineer. “It may provide temporary relief, but it won’t fix the issue.”

To ensure your car’s continued health and safety, it’s crucial to address the underlying issue that triggered the warning light.

FAQs

1. What is the best OBD2 scanner for clearing codes?

2. Can I use an OBD2 scanner to clear codes for any car?

Most OBD2 scanners work with vehicles manufactured since 1996. However, some newer vehicles may require a more advanced scanner.

3. Can clearing codes damage my car?

Clearing codes without addressing the underlying problem won’t damage your car. However, it’s essential to address the root cause of the issue to ensure your car’s safety and performance.

4. How often should I clear codes?

You only need to clear codes when your car’s “Check Engine” light is on. Clearing codes without a problem won’t do anything beneficial and may even mask a more serious issue.

5. Can I clear codes myself, or do I need to take my car to a mechanic?

You can clear codes yourself using an OBD2 scanner. However, if you’re unsure about the problem, it’s always best to consult a professional mechanic for diagnosis and repair.

6. Will clearing codes affect my car insurance?

Clearing codes shouldn’t affect your car insurance. Your insurance company will only be concerned about the underlying issue that caused the “Check Engine” light to come on.

7. What are some of the common reasons why my “Check Engine” light might come on?

The “Check Engine” light can come on for a variety of reasons, including:

Loose gas cap: This is one of the most common reasons for the light to come on.
Faulty oxygen sensor: The oxygen sensor monitors the amount of oxygen in the exhaust stream.
Bad spark plugs: Spark plugs ignite the fuel-air mixture in the engine.
Catalytic converter problems: The catalytic converter reduces harmful emissions.
Mass airflow sensor issues: The mass airflow sensor measures the amount of air entering the engine.

If you’re unsure about the cause of the “Check Engine” light, it’s always best to consult a professional mechanic for diagnosis and repair.
