AutoZone, and similar auto parts stores, offer free diagnostic testing, a valuable resource when your car is acting up. Understanding what Things Autozone Use To Check For Car Problems can help you prepare and understand the results. This article dives into the process, providing insights into the tools and tests employed to pinpoint potential issues.

Decoding the AutoZone Diagnostic Check

AutoZone’s free diagnostic check primarily focuses on reading your car’s On-Board Diagnostics (OBD-II) system. This system, standard in most vehicles since 1996, monitors various components and reports any malfunctions through Diagnostic Trouble Codes (DTCs). AutoZone’s code reader accesses these DTCs, revealing what’s potentially wrong.

What Does the OBD-II Scanner at AutoZone Actually Check?

The OBD-II scanner used at AutoZone primarily checks for emissions-related problems and some powertrain issues. It’s important to note that it doesn’t provide a complete diagnosis of all possible car problems.

• Emissions Systems: The scanner checks components like the catalytic converter, oxygen sensors, and evaporative emissions system. These play a vital role in controlling pollutants.
• Powertrain: The scanner looks at the engine, transmission, and related components, checking for issues affecting performance and drivability. This includes things like misfires, fuel system problems, and transmission errors.

Understanding the Limitations of AutoZone’s Diagnostic Check

While a free diagnostic check at AutoZone can be helpful, it’s crucial to understand its limitations. It won’t identify mechanical problems like worn brakes, suspension issues, or problems with the cooling system.

• Focus on Codes: The check primarily focuses on retrieving and interpreting DTCs. It doesn’t perform physical inspections or in-depth testing.
• Not a Substitute for Professional Diagnosis: Think of it as a starting point, not a definitive diagnosis. A qualified mechanic can perform a comprehensive inspection to identify the root cause of the problem.

How to Prepare for an AutoZone Diagnostic Check

Getting ready for an AutoZone diagnostic check is simple. Just make sure your car is accessible and the check engine light is on. If the light isn’t on, there may not be any stored codes for the scanner to retrieve.

What to Expect After the Check

After the check, an AutoZone employee will provide you with a printout of the DTCs found. They can explain what the codes mean in general terms. Remember, they are not mechanics, so they cannot provide specific repair advice.

“A DTC is a clue, not the entire story,” says John Peterson, a veteran automotive technician with 25 years of experience. “It points you in the right direction but requires further investigation to pinpoint the exact issue.”

Taking the Next Steps After an AutoZone Diagnostic Check

Once you have the DTCs, you have a few options. You can research the codes online, consult a repair manual, or take your car to a qualified mechanic for further diagnosis and repair.

“Don’t automatically assume the worst when you see a code,” advises Sarah Miller, a certified ASE Master Technician. “Many issues can trigger the same code, so a proper diagnosis is essential.”

Understanding what things AutoZone use to check for car problems empowers you to make informed decisions about your vehicle’s maintenance and repair.
