8. Frequently Asked Questions

Here are some frequently asked questions about OBD-II scanners to help you better understand their functions and benefits:

8.1. What is an OBD-II Scanner?

An OBD-II scanner is a diagnostic tool that plugs into your car’s OBD port to access information from the onboard computer, allowing you to read and identify error codes, monitor systems in real-time, and predict potential problems. These scanners provide valuable insights into your vehicle’s condition, helping you make informed decisions about maintenance and repairs.

8.2. 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.

8.3. 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.

8.4. What Do DTCs Actually Mean?

DTCs are error codes generated by your car’s OBD system to indicate specific issues, consisting of a letter and four numbers that provide information about the system and nature of the problem. 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 describe what these error codes mean, with more advanced models providing more information.

8.5. How to Choose the Best OBD-II Scanner for You

To choose the best OBD-II scanner for your needs, consider whether you prefer a handheld device with its own screen or a wireless scanner that connects to your smartphone, along with key criteria such as easy setup, fault explanations, I/M readiness check, accuracy, size, weight, live data, graphs, and warranty.

8.6. Easy Setup

If it takes forever to set up the scanner, you probably won’t use it to diagnose a problem early.

8.7. 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.

8.8. 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.

8.9. Accuracy

A scanner is worthless if its results aren’t accurate, because the only thing worse than no information is incorrect information.

8.10. 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.

8.11. Live Data

By tapping into the car’s engine speed, timing and other parameters, the right scanner can help track down an intermittent problem.

8.12. Graphs

Numbers are good, but a visual representation of it is much better, particularly if you’re comparing before and after.

8.13. 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.

8.14. How We Test OBD-II Scanners

To test OBD2 scanners, we connect each scanner to a vehicle’s OBD-II port and measure its ability to report the car’s vehicle identification number (VIN), monitor engine and vital systems, and display operating data accurately. We also evaluate the scanner’s ease of use, setup process, and the quality of the information provided.
