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. Mechanics use these scanners to figure out what’s wrong with your car, reading and identifying error codes. More advanced models can monitor your car’s systems in real-time and predict future problems.

According to the Environmental Protection Agency (EPA), OBD-II systems have been standardized since 1996 to monitor the performance of a vehicle’s emission control systems.

9. What is the OBD-II port?

The On-Board Diagnostics Version Two (OBD-II) port is a standardized port found on almost all 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. It allows devices like OBD-II scanners, insurance black boxes, and dash cams to interface with the onboard computer.

If you’re unsure where an OBD-II scanner plugs in, you can find resources online that show the OBD-II port location on North American cars or worldwide.

10. What is a DTC?

DTC stands for Diagnostic Trouble Code, which is the error code a car’s OBD system generates when it spots an issue. These codes are read by OBD-II scanners, allowing the user to figure out what’s going on under the hood. Some DTC codes are standardized across different vehicles, while others are specific to individual manufacturers.

11. What do DTCs actually mean?

DTCs are composed of a letter and numbers that indicate the car’s system experiencing the issue and the specific fault.

• The first letter indicates the system: Powertrain (P), Body (B), Chassis (C), or Network (N).
• The second character designates whether the code is generic (0) or manufacturer-specific (1).
• The third character identifies the specific system: fuel and air metering (1), injector circuit (2), ignition system or misfire (3), auxiliary emissions (4), vehicle speed controls and idle control systems (5), computer auxiliary outputs (6), transmission and gearbox faults (7, 8, and 9), and hybrid-specific propulsion faults (A, B, and C).
• The fourth and fifth characters confirm the exact fault, ranging from 0 to 99.

OBD-II scanners can describe what these error codes mean, with more advanced models providing additional information.

There are over 5,000 possible DTC errors, but not all indicate critical issues. Some may simply warn you that the engine temperature is a little too high.

12. How to choose the best OBD-II scanner for you?

Choosing the best OBD-II scanner involves considering several factors, including the type of device (handheld or wireless), ease of setup, fault explanations, I/M readiness check, accuracy, size, weight, live data, graphs, and warranty.

• Easy Setup: A scanner that is easy to set up will encourage frequent use for early problem diagnosis.
• Faults and Explanations: The best scanners not only identify faults but also explain their meaning, helping you decide whether to fix the issue yourself or consult a mechanic.
• I/M Readiness Check: A good scanner will run major engine and emissions tests to determine if your car will pass inspection.
• Accuracy: Accurate results are crucial, as incorrect information can lead to misdiagnosis and unnecessary repairs.
• Size and Weight: A compact and lightweight scanner is more likely to be kept in your car for on-the-road diagnostics.
• Live Data: Access to live data, such as engine speed and timing, can help track down intermittent problems.
• Graphs: Visual representations of data can make it easier to compare performance before and after repairs.
• Warranty: A good warranty, preferably lifetime, ensures that your scanner will last as long as your car.

13. How are OBD-II scanners tested?

OBD-II scanners are tested by connecting them to a vehicle’s OBD-II port and verifying that they can report the car’s vehicle identification number (VIN). Wireless scanners are connected to devices via Bluetooth or Wi-Fi. The scanner’s ability to monitor engine and vital systems, provide accurate data, and clear error codes is then evaluated.

According to a study by the National Institute for Automotive Service Excellence (ASE), the accuracy of OBD-II scanners is critical for effective vehicle diagnostics and repair.

14. What information is provided during OBD-II scanner testing?

During OBD-II scanner testing, several key pieces of information are monitored and evaluated:

• Vehicle Identification Number (VIN): Verifying that the scanner can accurately read and report the car’s VIN is the first step in ensuring compatibility and proper function.
• Engine Data: Monitoring engine data such as speed, timing, and coolant temperature provides insights into the car’s performance and helps identify potential issues.
• Error Codes: Identifying and interpreting error codes is a primary function of OBD-II scanners, allowing users to diagnose problems and take appropriate action.
• Live Data: Displaying live data in real-time helps track intermittent issues and assess the impact of repairs.
• I/M Readiness: Checking the car’s readiness for inspection and maintenance (I/M) tests ensures compliance with emissions standards.

By thoroughly testing these aspects, the effectiveness and reliability of OBD-II scanners can be assessed.
