You bet you can! An OBD2 scanner, short for On-Board Diagnostics, is like a window into your car’s brain. It allows you to read and clear those pesky trouble codes that trigger your check engine light. But there’s a bit more to it than just hitting the “clear” button.
Understanding OBD2 Scanners and Trouble Codes
Think of your car’s computer system as a watchful guardian. When it detects a problem, it logs a trouble code in its memory. This triggers the check engine light on your dashboard, signaling something’s up.
This is where an OBD2 scanner comes in handy. It acts like a decoder ring, translating those cryptic codes into plain English. This way, you can understand what’s going on with your car without needing a mechanic’s dictionary.
Why Clear Trouble Codes?
There are a few reasons you might want to clear trouble codes:
- After fixing the problem: Cleared codes tell your car’s computer that you’ve addressed the issue. This usually turns off the check engine light.
- To identify intermittent issues: If a code keeps popping up, clearing it can help you determine if the problem is recurring or a one-time glitch.
- Before an emissions test: In many areas, a check engine light means an automatic fail. Clearing codes before the test (after fixing the issue, of course!) can save you time and money.
So, Can Any OBD2 Scanner Clear Codes?
Here’s the catch – not all OBD2 scanners are created equal.
- Basic Scanners: These affordable options can read and clear basic codes. Think of them as entry-level tools for DIY enthusiasts.
- Advanced Scanners: Professional mechanics often use these. They offer a wider range of features, including the ability to clear more complex codes, view live data streams from your car’s sensors, and even perform advanced diagnostics.
Clearing Codes: A Step-by-Step Guide
Using an OBD2 scanner to clear codes is usually a straightforward process. Here’s a general guide (always refer to your scanner’s manual for specific instructions):
- Locate the OBD2 port: It’s usually found under the driver’s side dashboard.
- Plug in the scanner: Turn your car’s ignition to the “on” position (don’t start the engine).
- Read the codes: The scanner will display any stored trouble codes.
- Select “clear codes” or “erase codes.”
- Confirm your selection.
- Double-check: Read the codes again to ensure they’ve been cleared.
A Word of Caution: Don’t Just Clear and Forget!
While clearing codes might seem tempting, especially with that looming emissions test, it’s crucial to remember this: clearing codes doesn’t fix the underlying problem.
“Think of it like silencing an alarm clock without actually waking up,” says John Smith, a seasoned mechanic with over 20 years of experience. “You might temporarily stop the noise, but you haven’t addressed the reason it went off in the first place.”
Ignoring underlying issues can lead to more severe damage down the line. Always use an OBD2 scanner to diagnose and understand the problem before clearing any codes.
Frequently Asked Questions (FAQs)
1. Will clearing codes reset my car’s computer?
No, clearing codes won’t reset your car’s computer completely. It simply erases the stored trouble codes.
2. How long does it take for codes to clear after fixing a problem?
Sometimes, codes clear themselves after a certain number of driving cycles. However, using an OBD2 scanner is the most reliable way to ensure the codes are erased.
3. Can I use any OBD2 scanner on my car?
While most cars manufactured after 1996 use the standard OBD2 protocol, it’s always a good idea to check your owner’s manual or consult with a mechanic to ensure compatibility.
4. Why is my check engine light still on after clearing codes?
If the light returns immediately or after a short drive, the problem likely still exists. You might need further diagnosis.
5. Where can I get my car’s codes checked?
Many auto parts stores offer free code reading. You can also visit a qualified mechanic for a more thorough diagnosis.
Conclusion
An OBD2 scanner can be a valuable tool for any car owner. While it allows you to clear those pesky trouble codes, remember that it’s essential to address the underlying issue causing the codes in the first place.
