Ever walked into a mechanic’s shop and felt intimidated by the jargon? You’re not alone! The automotive world is full of complex terms, and sometimes it feels like you need a dictionary just to understand what’s wrong with your car. One phrase that often pops up in online forums and discussions is “AAS degree on an OBD2 scan tool.” It sounds impressive, but what does it actually mean? Let’s break it down.
Unraveling the Mystery: AAS Degrees and Scan Tools
The AAS Degree: Education for Automotive Technicians
An AAS degree stands for an Associate of Applied Science. It’s a two-year college degree that provides focused training in a specific field. For aspiring automotive technicians, an AAS degree in Automotive Technology is a valuable asset.
Imagine Sarah, a young woman passionate about cars since she was a kid, tinkering with her dad in their garage in suburban Chicago. Sarah enrolls in an AAS program at a community college. She dives deep into subjects like:
- Engine repair and performance: Understanding the intricate workings of engines, from combustion cycles to fuel injection systems.
- Brake systems: Learning about disc and drum brakes, hydraulics, and ABS technology.
- Electrical systems: Mastering the complex network of wires, sensors, and computers that control modern vehicles.
- OBD2 diagnostics: This is where our scan tools come in! Sarah learns how to use these tools to diagnose problems, read error codes, and monitor vehicle performance.

The OBD2 Scan Tool: Your Car’s Translator
OBD2 stands for On-Board Diagnostics, generation two. It’s a standardized system that allows external devices, like scan tools, to communicate with your car’s computer. Think of it as a translator between you and your car.
Picture this: You’re driving down Highway 1 along the California coast, enjoying the breathtaking views, when suddenly your “Check Engine” light pops up. Your trusty OBD2 scan tool can help you understand why:
- Reading error codes: The scan tool can retrieve Diagnostic Trouble Codes (DTCs) stored in your car’s computer. These codes act like clues, pointing to potential issues.
- Live data streaming: Imagine watching your car’s vital signs in real-time. Scan tools can display data from various sensors, like engine speed, coolant temperature, and oxygen sensor readings.

Connecting the Dots: Why the Confusion?
So, where does the idea of an “AAS degree on a scan tool” come from? It seems to stem from a misunderstanding of how these two elements relate to each other.
Here’s the key takeaway: An OBD2 scan tool itself doesn’t have an AAS degree. It’s a tool, not a graduate! However, a skilled technician with an AAS degree in Automotive Technology would have received extensive training on how to effectively use an OBD2 scan tool for accurate diagnosis and repair.
Think of it like this: A high-quality paintbrush doesn’t automatically make you a talented artist. It takes years of practice, training, and understanding of techniques to create a masterpiece. Similarly, an OBD2 scan tool is a powerful tool in the hands of a knowledgeable technician, but it’s not a substitute for proper education and experience.
Navigating the World of OBD2 Scan Tools: Your Questions Answered
What should I look for when buying an OBD2 scan tool?
Choosing the right scan tool depends on your needs and expertise.
- For basic DIY maintenance: A simple code reader can help you check and clear engine codes.
- For more advanced diagnostics: Look for features like live data streaming, ABS and airbag system access, and the ability to perform bi-directional controls (sending commands to your car’s modules).
It’s always a good idea to research different models, read reviews, and compare features before making a purchase.
Can an OBD2 scan tool fix my car?
While an OBD2 scan tool can help you identify potential problems, it can’t magically fix them. It’s an essential diagnostic tool, but the actual repairs often require mechanical expertise and specialized tools.
Do I need a professional-grade scan tool?
Professional-grade scan tools offer advanced features and functionalities that are more suited for experienced mechanics and technicians. While they might seem tempting, they can be expensive and complex to use for the average car owner.

- P0300: Random/Multiple Cylinder Misfire Detected
- P0171: System Too Lean (Bank 1)
- P0172: System Too Rich (Bank 1)
How often should I use an OBD2 scan tool?
It’s a good practice to scan your car for codes periodically, even if there are no warning lights illuminated. This can help you catch potential issues early on.
Can an OBD2 scan tool tell me the remaining life of my car battery?
While some advanced scan tools might provide battery voltage readings, they cannot accurately predict the remaining life of your battery.
