3. What is an OBD-II Scanner?
If you’ve ever wondered how technicians figure out what the problem is with your car, it’s not because they strip the whole thing down and figure it out by hand. Instead they plug a diagnostic scanner into your car’s OBD port to access information from the onboard computer.
These OBD-II scanners, at their most basic, are able to read and identify error codes flagged by your car – which has already realized something is wrong. More advanced models are also able to monitor your car’s systems in real-time, and in some cases predict where future problems may occur.
4. Comprehensive Guide to Selecting the Best OBD2 Scan Tool Under $100
An OBD2 scanner is a tool that connects to your vehicle’s onboard computer to read diagnostic trouble codes (DTCs). These codes can help you identify the source of a problem, whether it’s a minor issue or a more serious concern.

6. What is the OBD-II port?
The On-board Diagnostics Version Two (OBD-II) port is the standard port on almost all passenger vehicles sold in the United States since 1996, in Canada since 1998, in the European Union since 2004, and in Australia, Mexico and New Zealand since 2006.
This port is where you plug into the car and interface with the onboard computer. A variety of devices can be plugged into the OBD-II port including OBD-II scanners, insurance black boxes, and more recently dash cams.
7. What is a DTC?
DTC is short for Diagnostic Trouble Code, which is the error code a car’s OBD system generates when it spots an issue. These are the codes read by OBD-II scanners that allow the user to figure out what’s going on under the hood. There are a lot of standardized DTC codes that are the same across different makes and models of vehicle, though some manufacturers employ their own DTCs that are unique to one or more of their vehicles
8. What do DTCs actually mean?
If you’re unfamiliar with how DTCs are written, then they probably look like complete gibberish – a random selection numbers and letters that mean very little to you. Fortunately there is some logic, which will give you an idea of what errors the car has detected.
The first letter confirms which of the car’s main systems is experiencing the issue. Those are the Powertrain (P), Body (B), Chassis (C) and Network (N). The second is a number designating whether this is a generic code (0) or a manufacturer specific code (1).
The third character then identifies exactly which system is experiencing the issue.
- 1 is fuel and air metering
- 2 is an injector circuit specific fuel and air metering code
- 3 is the ignition system or a misfire
- 4 is an auxiliary emissions code
- 5 concerns vehicle speed controls and idle control systems
- 6 is for computer auxiliary outputs
- 7, 8 and 9 are for transmission and gearbox faults
- A, B and C are for hybrid-specific propulsion faults
The fourth and fifth character then confirms the exact fault, and can be any number between 0 and 99.
OBD-II scanners are able to describe what these error codes mean, though more advanced models will be able to give you more information. It may require some time on Google, and as you can imagine there are a lot of possible DTC errors you may encounter. Over 5,000, in fact.
9. Key Features to Look For
- Compatibility: Ensure the scan tool supports Mercedes-Benz vehicles.

10. Before You Buy: Compatibility with Your Mercedes-Benz Model
Before purchasing an OBD2 scan tool, verify that it’s compatible with your specific Mercedes-Benz model. Compatibility information is typically available on the product’s website or packaging. This ensures that the tool can accurately read and interpret data from your vehicle’s computer.
11. Types of OBD2 Scan Tools
11.1. Code Readers
Code readers are the most basic type of OBD2 scan tools. They can read and clear DTCs, but they typically don’t offer advanced features like live data or graphing. Code readers are a good option for those who just want to be able to diagnose basic problems.
11.2. Scan Tools
Scan tools are more advanced than code readers. They can read and clear DTCs, but they also offer features like live data, graphing, and the ability to perform some basic tests. Scan tools are a good option for those who want to be able to diagnose more complex problems.
11.3. Professional Scan Tools
Professional scan tools are the most advanced type of OBD2 scan tools. They offer all of the features of code readers and scan tools, plus they can perform more advanced tests, such as bidirectional control and component testing. Professional scan tools are a good option for mechanics and other automotive professionals.
12. Benefits of Using an OBD2 Scan Tool
- Saves Money: Diagnose problems yourself and avoid expensive mechanic fees.
- Identifies Issues Early: Catch potential problems before they become major repairs.
- Empowers You: Gain a better understanding of your vehicle’s health.
- Facilitates Informed Decisions: Make informed decisions about repairs and maintenance.
- Ensures Vehicle Readiness: Check if your car is ready for emissions tests.
13. Maintenance Tips for Mercedes-Benz
Regular maintenance is essential for keeping your Mercedes-Benz in top condition.
13.1. Routine Inspections
Regularly inspect your vehicle for any signs of wear and tear. Check the tires, lights, and fluid levels.
13.2. Oil Changes
Follow the manufacturer’s recommendations for oil changes. Using the right type of oil is crucial for engine performance and longevity.
13.3. Brake Maintenance
Keep your braking system in good condition. Replace brake pads and rotors as needed.
13.4. Tire Care
Ensure your tires are properly inflated and rotated regularly. This improves fuel efficiency and extends tire life.
14. Understanding OBD2 Codes
OBD2 codes are five-character codes that indicate a specific problem with your vehicle. The first character indicates the system that’s affected:
- P = Powertrain
- B = Body
- C = Chassis
- U = Network
The second character indicates whether the code is generic (0) or manufacturer-specific (1). The remaining characters indicate the specific problem.
15. Where to Buy OBD2 Scan Tools
- Online Retailers: Amazon, eBay, and other online retailers offer a wide selection of OBD2 scan tools.
- Auto Parts Stores: Local auto parts stores like AutoZone and Advance Auto Parts also carry OBD2 scan tools.
- Specialty Tool Stores: Stores that specialize in tools and equipment may offer a wider selection of high-quality OBD2 scan tools.
16. How to Choose the Best OBD-II scanner for you
If you’re looking for insights into how your vehicle is working or what’s wrong under the hood, there’s no better way than to plug in one of the best OBD-II scanners and read the results.
After all, it’s how your car dealer or repair shop would figure out what’s wrong with your car when you drive (or are towed) in. Why shouldn’t you have the same information? Not all the best OBD-II scanners are created equal. There are two general types of devices.
Handheld OBD-II scanners come with their own screen and cable to plug into the car’s OBD port. Wireless OBD2II scanners plug into the port, but then connect via Bluetooth to a smartphone or tablet to display their findings.
Whichever type you choose, there are several high-performance OBD-II scanners that cost less than $200. A couple are less than $30. What’s important to remember is that the best OBD-II scanners provide the right mix of size, weight and the ability to read your car’s fault codes and live data. The most important criteria are:
- Easy setup. If it takes forever to set up the scanner, you probably won’t use it to diagnose a problem early.
- Faults and explanations. The best OBD-II scanners not only tell you the faults your car has but also can explain the meaning so you can either fix it yourself or tell a mechanic.
- I/M Readiness check. A good scanner will run the major engine and emissions tests to see if you’ll pass your state’s inspection.
- Accuracy. A scanner is worthless if its results aren’t accurate, because the only thing worse than no information is incorrect information.
- Size and weight. If the scanner is heavy and bulky, chances are it’ll stay in your toolbox and not in the car to help you on the road.
- Live data. By tapping into the car’s engine speed, timing and other parameters, the right scanner can help track down an intermittent problem.
- Graphs. Numbers are good, but a visual representation of it is much better, particularly if you’re comparing before and after.
- Warranty. You expect your car to last at least eight or 10 years, so why shouldn’t your OBD-II scanner? That said, the best offer a lifetime warranty that should outlast your ride.
