Frequently Asked Questions About OBD2 Scanners
What exactly is an OBD2 Scanner?
Mechanics use OBD2 scanners to diagnose car problems by connecting to the car’s OBD port and accessing data from the onboard computer. These scanners read error codes, indicating detected issues. Advanced models also monitor real-time data and predict potential future problems.
What is the OBD2 Port?
The On-Board Diagnostics Version Two (OBD2) port is a standardized port found in most modern vehicles. It has been standard in cars sold in the United States since 1996, Canada since 1998, the European Union since 2004, and in New Zealand, Australia, and Mexico since 2006. This port allows connection to the car’s computer for diagnostics and other purposes.
You can find your OBD2 port location using resources like this guide for North American cars or this worldwide guide.
What is a DTC?
DTC stands for Diagnostic Trouble Code. These are error codes generated by a car’s OBD system when it detects a problem. OBD2 scanners read these codes to help users understand the nature of the issue. While many DTCs are standardized across car brands, some manufacturers use unique, proprietary codes.
Understanding DTC Meanings
DTCs may seem cryptic, but they follow a logical structure. The first character indicates the affected vehicle system: Powertrain (P), Body (B), Chassis (C), or Network (N). The second character is a number, ‘0’ for generic codes and ‘1’ for manufacturer-specific codes.
The third character specifies the subsystem:
- 1: Fuel and air metering
- 2: Injector circuit fuel and air metering
- 3: Ignition system or misfire
- 4: Auxiliary emissions
- 5: Vehicle speed controls and idle control
- 6: Computer auxiliary outputs
- 7, 8, 9: Transmission and gearbox
- A, B, C: Hybrid propulsion
The fourth and fifth characters pinpoint the specific fault, ranging from 0 to 99. OBD2 scanners can often provide descriptions of these codes, and online resources like Google can also be helpful in deciphering them. It’s important to remember that not all DTCs indicate critical problems; some may signal minor issues like a slightly elevated engine temperature.
Choosing the Right OBD2 Scanner for You
Using an OBD2 scanner is the most effective way to understand your car’s health and diagnose problems. It’s the same technology used by mechanics, giving you access to valuable information. When selecting an OBD2 scanner in NZ, consider these factors:
Types of Scanners:
- Handheld OBD2 scanners: Feature an integrated screen and cable.
- Wireless OBD2 scanners: Connect to smartphones or tablets via Bluetooth.
Both types offer high-performance options under $200 NZD, with some available for under $50 NZD. Key criteria for choosing the best OBD2 scanner include:
- Easy Setup: Quick and straightforward setup is crucial for frequent use.
- Fault Explanation: Scanners should explain fault codes clearly for DIY repairs or mechanic communication.
- I/M Readiness Check: Essential for pre-WOF checks in NZ, ensuring your car will pass emissions and safety inspections.
- Accuracy: Reliable and accurate results are paramount.
- Size and Weight: Portability is important for on-the-road diagnostics.
- Live Data: Real-time data monitoring is helpful for tracking intermittent issues.
- Graphs: Visual data representation enhances understanding.
- Warranty: Look for scanners with good warranties, ideally lifetime warranties for long-term value.
Consider whether you prefer a wireless scanner for smartphone connectivity or a handheld unit with its own display. Lifetime warranties and software updates ensure your scanner remains current. For handheld scanners, prioritize screen size and clarity. Rugged designs are beneficial for durability. Extra features like multimeters or manufacturer-specific code reading can also be valuable. With a wide range of options available under $100 NZD, OBD2 scanners offer excellent value, potentially saving you significant mechanic costs.
How We Test OBD2 Scanners
We rigorously test OBD2 scanners using a 2014 Audi A4 Allroad over several weeks in various driving conditions. Testing includes:
- VIN Verification: Ensuring each scanner correctly identifies the vehicle identification number (VIN).
- Connectivity Testing: For wireless scanners, we test Bluetooth and Wi-Fi connections with devices like iPads, Microsoft Surfaces, and Samsung Galaxy phones. Handheld scanners are tested for direct OBD port connection.
- Cable Length and Wireless Range: Measuring cable length for handheld scanners and wireless range for Bluetooth models.
- Live Data Monitoring: Monitoring engine performance and vital systems during car operation.
- Fault Code Testing: Simulating a fault by disconnecting the engine oil temperature sensor to assess fault code detection and detail.
- Fault Resolution and Code Clearing: Verifying the scanner’s ability to clear fault codes after issue resolution.
- Road Testing: Evaluating the scanner’s ability to display real-time operating data like engine speed, timing, and coolant temperature in different formats (numbers, graphs, gauges).
Our testing process ensures we evaluate OBD2 scanners comprehensively, providing you with reliable recommendations for the New Zealand market.
