5. Understanding OBD-II Scanners and DTCs

Delving into the technical aspects can help you better utilize these tools.

5.1 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. These scanners read and identify error codes, monitor car systems in real-time, and predict future problems.

5.2 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. It’s where you plug into the car and interface with the onboard computer. According to the Environmental Protection Agency (EPA), this standardization was mandated to ensure all vehicles could be easily tested for emissions compliance.

5.3 What is a DTC?

DTC stands for Diagnostic Trouble Code, the error code generated by a car’s OBD system when it spots an issue. These codes are read by OBD-II scanners to help users figure out what’s going on under the hood.

5.4 What do DTCs Actually Mean?

DTCs consist of a letter and numbers that indicate the system and specific issue. The first letter confirms which of the car’s main systems is experiencing the issue: Powertrain (P), Body (B), Chassis (C), and Network (N). The second character designates whether it’s a generic code (0) or a manufacturer-specific code (1).

The third character identifies the specific system experiencing the issue:

• 1: Fuel and air metering
• 2: Injector circuit specific fuel and air metering code
• 3: Ignition system or a misfire
• 4: Auxiliary emissions code
• 5: Vehicle speed controls and idle control systems
• 6: Computer auxiliary outputs
• 7, 8, and 9: Transmission and gearbox faults
• A, B, and C: Hybrid-specific propulsion faults

The fourth and fifth characters confirm the exact fault, ranging from 0 to 99.

6. How We Test OBD-II Scanners

To test the best auto scanner for the money, we follow a comprehensive testing process.

6.1 What is Our Testing Methodology?

Our testing involves connecting each scanner to a vehicle’s OBD-II port to report the car’s VIN. For wireless scanners, we connect via Bluetooth or Wi-Fi to an Apple iPad Pro, Microsoft Surface, or Samsung Galaxy S9+ phone. Handheld scanners are simply plugged into the OBD-II port for power.

6.2 What Parameters Do We Monitor?

We monitor the engine and vital systems with the car running, and then disconnect the engine’s oil temperature sensor. We check the details provided by the scanner, fix the problem, turn off the check engine light, and erase the error code.

6.3 How Do We Evaluate Performance?

We evaluate performance by assessing whether the scanner can display operating data such as engine speed, timing, and coolant temperature, and whether the data is reported as numbers, graphs, or auto-style gauges.

7. Frequently Asked Questions About OBD-II Scanners

Here are some common questions about OBD-II scanners:

7.1 What is an OBD-II Scanner and How Does It Work?

An OBD-II scanner is a device that connects to your car’s onboard computer via the OBD-II port to read diagnostic trouble codes (DTCs) and access real-time data about your vehicle’s performance. According to a report by the National Institute for Automotive Service Excellence (ASE), understanding these codes can help you diagnose and fix many common car problems.

7.2 What is the Difference Between an OBD-II Scanner and a Code Reader?

While the terms are often used interchangeably, an OBD-II scanner typically offers more advanced features than a basic code reader. Scanners can often display live data, perform advanced tests, and provide more detailed information about the issue.

7.3 Can I Use an OBD-II Scanner on Any Car?

OBD-II scanners are compatible with most cars and trucks sold in the United States after 1996, as the OBD-II standard became mandatory then. However, some older or foreign vehicles may not be compatible.

7.4 Do I Need to Be a Mechanic to Use an OBD-II Scanner?

No, you don’t need to be a mechanic. Many OBD-II scanners are designed to be user-friendly, with clear instructions and easy-to-understand interfaces. However, understanding the diagnostic codes and data requires some basic automotive knowledge.

7.5 How Do I Interpret the Codes That the Scanner Provides?

The codes provided by the scanner, known as Diagnostic Trouble Codes (DTCs), can be looked up in a database or online to determine the issue. Many scanners also provide a brief description of the code’s meaning.

7.6 Can an OBD-II Scanner Fix My Car?

No, an OBD-II scanner can’t fix your car, but it can help you diagnose the problem so you can take the necessary steps to repair it. It identifies the issue, allowing you to address it yourself or take it to a mechanic.

7.7 How Often Should I Use an OBD-II Scanner?

You can use an OBD-II scanner whenever you notice a warning light or suspect there may be an issue with your vehicle. Regular use can help you catch minor problems before they become major repairs.

7.8 Are Wireless OBD-II Scanners as Good as Handheld Ones?

Both wireless and handheld OBD-II scanners have their pros and cons. Wireless scanners offer convenience and can display data on your smartphone or tablet, while handheld scanners are self-contained and don’t rely on external devices.

7.9 What is Live Data, and Why is It Important?

Live data refers to real-time information about your vehicle’s performance, such as engine speed, temperature, and sensor readings. It’s important because it can help you diagnose intermittent problems and monitor your vehicle’s overall health.
