13. Frequently Asked Questions
What is an OBD-II Scanner?
An OBD-II scanner is a device used to access information from a car’s onboard computer via the OBD port. It reads and identifies error codes, monitors systems in real-time, and can predict future problems.
What is the OBD-II Port?
The On-Board Diagnostics Version Two (OBD-II) port is a standard port found in most passenger vehicles sold since 1996 in the United States, 1998 in Canada, 2004 in the European Union, and 2006 in Australia, Mexico, and New Zealand. It allows devices to interface with the onboard computer.
What is a DTC?
DTC stands for Diagnostic Trouble Code, an error code generated by a car’s OBD system when it detects an issue. These codes are read by OBD-II scanners to help users understand what’s happening under the hood.
What do DTCs Actually Mean?
DTCs use a standardized format to indicate the type and location of a problem. The first letter indicates the system (Powertrain, Body, Chassis, or Network), followed by a number (0 for generic, 1 for manufacturer-specific). Subsequent characters identify the specific issue and fault.
14. How to Choose the Best OBD-II Scanner for You
Choosing the best OBD-II scanner depends on your needs and budget. Consider these factors:
- Easy Setup: The scanner should be easy to set up for quick diagnostics.

- I/M Readiness Check: The ability to run engine and emissions tests is crucial.
- Accuracy: Accurate results are essential for effective diagnostics.
- Size and Weight: A compact and lightweight scanner is easier to use and store.
- Live Data: Real-time monitoring of engine parameters helps track intermittent issues.
- Graphs: Visual data representation enhances analysis.
- Warranty: A long warranty ensures the scanner’s longevity.
Handheld scanners have their own screen and cable, while wireless scanners connect to smartphones via Bluetooth. Consider a scanner with lifetime warranty or software updates to stay current with automotive technology.
15. How We Test OBD-II Scanners
To test OBD-II scanners, we connect them to a vehicle’s OBD-II port and verify they can report the vehicle identification number (VIN). For wireless scanners, we establish connections with devices like Apple iPads and Samsung Galaxy phones. We monitor the engine and vital systems while the car is running.
We also test the accuracy of the scanners by disconnecting engine sensors and observing whether the scanner correctly identifies the issue and provides accurate data. Performance is assessed by driving the car and monitoring operating data, such as engine speed and coolant temperature.
