9. Frequently Asked Questions about OBD-II Scanners
9.1 What is an OBD-II Scanner?
An OBD-II scanner is a diagnostic tool that mechanics use to identify car problems by plugging into the car’s OBD port and accessing information from the onboard computer. These scanners read and identify error codes, and advanced models monitor car systems in real-time and predict future issues.
9.2 What is the OBD-II Port?
The On-board Diagnostics Version Two (OBD-II) port is a standard port in 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 interfaces with the onboard computer and is used for OBD-II scanners, insurance black boxes, and dash cams.
If you’re unsure where an OBD-II scanner plugs in, here’s how to find your car’s OBD-II port on North American cars. If you’re living elsewhere, here’s how to find your OBD-II/EOBD port worldwide.)
9.3 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. OBD-II scanners read these codes, helping users understand the problem. Standardized DTC codes are consistent across different vehicle makes and models, though some manufacturers use unique DTCs for their vehicles.
9.4 What do DTCs Actually Mean?
DTCs may appear confusing initially, but they follow a logical structure. The first letter indicates the affected 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 specifies the system experiencing the issue:
- 1: Fuel and air metering
- 2: Injector circuit-specific fuel and air metering
- 3: Ignition system or 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 specify the exact fault, ranging from 0 to 99. OBD-II scanners interpret these error codes, with advanced models providing more detailed information. There are over 5,000 possible DTC errors. While some DTCs indicate critical issues, others may simply warn of a slightly high engine temperature.
9.5 What are the Key Search Intents of OBD2 Scanner Users?
OBD2 scanner users typically have five key search intents:
- Finding the Best OBD2 Scanner: Users search for top-rated scanners based on features, price, and compatibility with their vehicle.
- Understanding OBD2 Codes: Users want to decipher diagnostic trouble codes (DTCs) to identify and fix car problems.
- Troubleshooting Car Issues: Users seek scanners that help diagnose and resolve specific issues like engine misfires or sensor failures.
- Performing Maintenance Checks: Users need scanners to monitor vehicle health, check emissions readiness, and perform routine maintenance.
- Comparing OBD2 Scanner Brands: Users compare different brands like Topdon, Launch, and Ancel to make an informed purchase.
10. How to Choose the Best OBD-II Scanner for You
To gain insights into your vehicle’s operation and identify potential issues, using one of the best OBD-II scanners is an excellent approach. It’s the same method dealerships and repair shops use. There are two main types of devices:
- Handheld OBD-II scanners: Feature their own screen and cable for connecting to the car’s OBD port.
- Wireless OBD2II scanners: Connect to the OBD port and transmit data to a smartphone or tablet via Bluetooth.
High-performance OBD-II scanners are available for under $200, with some costing less than $30. Key factors to consider include:
- Easy Setup: Quick setup ensures frequent use for early problem diagnosis.
- Faults and Explanations: The best scanners provide fault codes and clear explanations for effective repairs.
- I/M Readiness Check: Ensures your car passes state inspections by running engine and emissions tests.
- Accuracy: Accurate results are crucial for effective diagnostics.
- Size and Weight: Compact and lightweight scanners are more likely to be kept in the car for on-the-road assistance.
- Live Data: Access to engine speed, timing, and other parameters helps track intermittent issues.
- Graphs: Visual representations of data are more effective than numbers.
- Warranty: A lifetime warranty ensures the scanner lasts as long as your car.
Additional considerations include whether you prefer a scanner that connects to your phone or a handheld unit with its own display, longevity, lifetime warranty or software updates, screen size, and durability. Some models offer extras like an electrical multimeter, manufacturer-specific codes, and PDF export capabilities. These sophisticated devices are priced similarly to professional-level scanners, making them a valuable investment.
11. How We Test OBD-II Scanners
To evaluate OBD2 scanners, we use a 2014 Audi A4 Allroad over several weeks, both in the garage and on the road. We connect each scanner to the car’s OBD-II port to verify its ability to report the vehicle identification number (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 powered directly through the OBD-II port.
We measure the cord length of handheld scanners and the wireless range of others. With the car running, we monitor the engine and vital systems, then disconnect the engine’s oil temperature sensor. We check the scanner’s details, fix the problem, turn off the check engine light, and erase the error code.
During road tests, we assess the scanner’s ability to display operating data such as engine speed, timing, and coolant temperature, noting whether the data is presented as numbers, graphs, or gauges.
Regardless of the OBD-II scanner used, understanding fault codes is essential. All fault codes have four numbers and a letter prefix:
- Powertrain (P)
- Body (B)
- Chassis (C)
- Undefined (U)
Of the approximately 5,000 diagnostic fault codes, some are generic (air temperature, throttle position) and start with a 0. Others are specific to carmakers and start with a 1, indicating a special piece of hardware or a more in-depth analysis. For example, a P0098 code typically indicates an issue with the engine’s intake air temperature sensor, while a Ford with a P1112 specialty fault code means the intake air temperature sensor is reporting values intermittently and should be replaced.
