8. 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. These scanners read and identify error codes, monitor car systems in real-time, and predict future problems. According to the Environmental Protection Agency (EPA), OBD-II systems have been mandatory on all cars sold in the US since 1996 to monitor emissions-related components.
9. What Is the OBD-II Port?
The On-Board Diagnostics Version Two (OBD-II) port is a standardized port found on most passenger vehicles sold in the United States (since 1996), Canada (since 1998), the European Union (since 2004), and Australia, Mexico, and New Zealand (since 2006). This port allows you to interface with the onboard computer, and various devices, including OBD-II scanners, insurance black boxes, and dash cams, can be plugged into it.
10. 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, read by OBD-II scanners, help users understand what’s happening under the hood. Standardized DTC codes are consistent across different vehicle makes and models, although some manufacturers use unique DTCs.
11. What Do DTCs Actually Mean?
DTCs consist of a letter and numbers indicating the car’s system experiencing the issue. The first letter identifies the system: Powertrain (P), Body (B), Chassis (C), or Network (N). The second character is a number indicating whether the code is generic (0) or manufacturer-specific (1). The third character identifies the specific system experiencing the issue, such as fuel and air metering (1), injector circuit (2), or the ignition system (3). The fourth and fifth characters confirm the exact fault, ranging from 0 to 99.

13. How Are Car OBD-II Scanners Tested?
Car OBD-II scanners are tested by connecting them to a vehicle’s OBD-II port, checking for vehicle identification number (VIN) reporting, and measuring cord length or wireless range. The engine is monitored, and vital systems are observed to ensure the scanner displays operating data accurately. The scanner’s ability to report data as numbers, graphs, or gauges is also assessed.
