Are you in the market for an OBD2 scanner and feeling overwhelmed by the sheer variety of options? Choosing the right OBD scan tool can be daunting, given the diverse types and price points available. This guide is designed to clarify the different categories of OBD2 scanners, helping you pinpoint the perfect tool for your specific needs, whether for personal car maintenance, professional automotive work, or managing a repair workshop. For further assistance in your selection process, we highly recommend reviewing 5 Essential Steps To Consider Before Buying an OBD Scanner.
The most crucial step in buying an OBD scan tool is identifying your exact requirements. What do you need the scanner for? Basic data monitoring, reading and diagnosing engine trouble codes, or more complex diagnostics and programming? Your needs will dictate the necessary car coverage, features, and functions of the OBD2 scanner.
Consider this: a mechanic specializing in European vehicles might prefer a professional diagnostic scanner focused solely on European brands. Similarly, a mobile mechanic may not require advanced ECU coding capabilities if their work primarily occurs outside a fully equipped shop. Remember, the most expensive scanner isn’t always the best fit for you.
Before diving into the types, ensure your vehicle is OBD2 compatible. While a 16-pin OBD port is common, it doesn’t guarantee OBD2 compliance. Consult our OBD2 Australia Compatibility List to verify your vehicle. If your car isn’t listed but is newer than a 2012 model, it’s likely OBD2 compatible.
Here’s a breakdown of common OBD2 scanner types:
1. Engine OBD2 Code Readers
Engine code readers are entry-level OBD2 scanners specifically designed for diagnosing engine-related issues. These tools are ideal for understanding why your “Check Engine” light is illuminated. If the problem originates within the engine system, the OBD2 scanner will identify the fault code, explain the issue, and allow you to clear the code, turning off the Check Engine light. When choosing an engine code reader, consider factors like price, brand reputation, and the inclusion of enhanced Mode 6 features. Mode 6 capability provides access to comprehensive testing, including fuel system checks, emission system analysis, and oxygen sensor tests.
2. Bluetooth/WiFi OBD2 Scanners for Smartphones
Bluetooth and WiFi OBD2 scanners offer a wireless connection between your vehicle’s computer and your smartphone (Android or iPhone) via the OBD2 port. These scanners vary in compatibility with devices and apps, connection type (Bluetooth or WiFi), and data transfer speeds. Our range includes Bluetooth & WiFi OBD2 engine scanners, AFR Wideband smartphone gauges, and battery testers/monitors for smartphones. Generally, these scanners excel at real-time monitoring of various diagnostic parameters and trip data. For diagnostic purposes, most apps primarily focus on engine diagnostics unless specified as multi-system or bi-directional capable.

3. OBD2 Gauges & Monitors
OBD2 gauges and monitors resemble engine code readers and other basic OBD2 scanners, but instead of relying on a separate handheld device for display, they present OBD2 data as real-time gauges directly in your vehicle. These tools are popular among drivers who want to continuously monitor crucial vehicle parameters like temperature and pressure sensors. OBD2 gauges can also display speed, fuel consumption, trip information, and associated costs. They are an excellent way to leverage OBD2 data for safer and more efficient driving habits.

4. Multi-System OBD Scan Tools
Multi-system scan tools expand diagnostic capabilities beyond just the engine, allowing you to diagnose various vehicle systems, including ABS, SRS, Body Control Modules, Transmission, and more. Depending on the specific scan tool, coverage can range from several systems to all vehicle systems, and may include OBD2 vehicles only or both OBD2 and older OBD1 vehicles. Some multi-system scanners also support heavy diesel vehicles. Many offer additional service reset functions like oil service resets, Steering Angle Sensor (SAS) resets, Diesel Particulate Filter (DPF) regeneration, and more. If you require these service functions, ensure you filter your options accordingly to narrow your search.

5. Single-Make OBD Scan Tools
For professionals or enthusiasts who need advanced features and functions but prefer not to invest in a scanner covering all vehicle brands, single-make scan tools are an ideal solution. These tools are designed to offer in-depth diagnostics for specific vehicle brands (typically 1 to 5 brands), providing access to most systems and necessary service/reset functions. Single-make scanners are perfect for personal use, specialized workshops, or dealerships that require multi-system diagnostic capabilities within a limited range of vehicle brands, without the expense of an all-makes scanner.

6. Professional OBD Scan Tools
Professional OBD scan tools represent the top tier of diagnostic equipment, designed for workshops and mechanics demanding comprehensive diagnostic capabilities, broad Australian market vehicle coverage, and advanced bi-directional control, coding, and programming functions. These scanners often include additional hardware features that enhance diagnostic capabilities, such as online search and support integration, customer management systems, automotive oscilloscopes, faster scanning speeds, and more.

7. Service Reset OBD Scan Tools
Service reset OBD scan tools are engineered to perform advanced service functions across a wide range of vehicles. Beyond basic code reading, these tools offer functionalities like oil service and mileage interval resets, Electronic Parking Brake (EPB) service, brake bleeding, battery replacement and programming, Tire Pressure Monitoring System (TPMS) functions, throttle body alignment, immobilizer functions, DPF regeneration, and many others.
8. OBD1 to OBD2 Cable Adapters
OBD1 to OBD2 cables and adapters facilitate the connection of your OBD scanner to older vehicles equipped with manufacturer-specific OBD ports, which predate the standardized OBD2 port. While these adapters enable physical connection, your scan tool must still be compatible with the specific diagnostic protocols and parameters of the older vehicle. These adapters bridge the gap, allowing modern scanners to interface with a broader range of vehicles.
