Navigating the world of automotive diagnostics can be daunting, especially when you’re faced with a plethora of OBD2 scanner types. If you’re in the market for an OBD II scanner and seeking clarity amidst the options, you’ve come to the right place. This guide is designed to demystify the different types of OBD scan tools available, ensuring you can confidently select the one that perfectly aligns with your specific needs. To further refine your selection process, we highly recommend exploring our resource on essential steps to consider before buying an OBD scanner, offering additional insights into making an informed decision.
The most critical step in purchasing an OBD scan tool is pinpointing your exact requirements. Are you a car enthusiast looking for personal diagnostics, a mobile mechanic, or managing a professional workshop? Your needs will vary significantly depending on whether you require basic data monitoring, trouble code reading, or advanced diagnostics and programming capabilities. These needs are primarily dictated by the car brands you work with, and the features you expect from your OBD scan tools for cars.
For instance, a mechanic specializing in Japanese vehicles might prioritize a professional diagnostic OBD scan tool with deep coverage of brands like Toyota, Honda, and Nissan. Conversely, a mobile mechanic focusing on general repairs might not need a high-end scan tool with extensive ECU coding if their work is primarily field-based. Remember, the most expensive OBD II scanner type isn’t always the optimal choice for your situation.
Before diving into the types, it’s crucial to confirm your vehicle’s OBD compatibility. While a 16-pin OBD port is standard on most modern cars, it doesn’t automatically guarantee OBDII compliance. Refer to our OBD2 Australia Compatibility List to verify your vehicle’s compatibility. As a general rule, vehicles newer than 2012, even if not on the list, are highly likely to be OBD2 compliant.
Let’s explore the diverse landscape of Obd Ii Scanner Types:
1. Engine OBD2 Code Readers
Engine code readers represent the entry point into OBDII diagnostics. These basic OBD II scanner types are specifically designed to diagnose engine-related trouble codes. If your ‘Check Engine Light’ illuminates, these tools can identify the issue, explaining why the light is on. They empower you to read, understand, clear, and reset engine fault codes and extinguish the Check Engine Light. When selecting an engine code reader, consider factors like price, brand reputation, and the inclusion of enhanced Mode 6 features. Mode 6 capability allows for in-depth testing, including fuel system, emissions, and oxygen sensor health checks.

2. Bluetooth/WiFi OBD2 Scanners for Smartphones
Bluetooth and WiFi OBD2 scanners offer a wireless bridge between your vehicle’s computer and your smartphone or tablet. Utilizing the OBD2 diagnostic port, these OBD II scanner types transmit car data to your Android or iPhone devices. Key differentiators include device compatibility (iOS, Android), connection type (Bluetooth, WiFi), app compatibility, and data transmission speed. Our range encompasses everything from basic Bluetooth OBD2 engine scanners to advanced AFR wideband smartphone gauges and battery testers. Typically, these are excellent for real-time monitoring of various diagnostic parameters and trip data. For comprehensive diagnostics beyond the engine, ensure the accompanying app explicitly advertises multi-system or bi-directional capabilities.

3. OBD2 Gauges & Monitors
OBD2 gauges and monitors share similarities with engine code readers but excel in real-time data visualization. Instead of relying on a handheld screen for codes, these OBD II scanner types display OBD2 data as live gauges directly in your vehicle. Popular among drivers who want continuous monitoring of crucial parameters like temperature and pressure sensors, OBD2 gauges can also display speed, fuel economy, and trip statistics. They provide a convenient way to leverage OBD2 data for safer and more economical driving habits. These are particularly useful for performance enthusiasts and those keen on tracking vehicle health in real-time.

4. Multi-System OBD Scan Tools
Multi-system scan tools elevate diagnostic capabilities beyond just the engine. These OBD II scanner types enable you to diagnose a broader spectrum of vehicle systems, including ABS (Anti-lock Braking System), SRS (Supplemental Restraint System/Airbags), transmission, body control modules, and more. Depending on the specific tool, coverage can range from several systems to comprehensive ‘all-system’ diagnostics, and may include both OBD2 and older OBD1 vehicles. Some multi-system tools even extend to heavy diesel vehicles. Many feature additional service reset functions like oil service reset, steering angle sensor (SAS) reset, DPF (Diesel Particulate Filter) regeneration, and more. If you require these advanced service functions, filter your options accordingly to narrow down your choices.

5. Single-Make OBD Scan Tools
For professionals or serious DIYers focused on specific car brands, single-make OBD scan tools offer a cost-effective solution. These professional OBD II scanner types provide deep diagnostic capabilities comparable to all-brand scanners but are tailored to one to five specific vehicle manufacturers. Single-make tools deliver efficient and comprehensive diagnostics for your chosen brands, granting access to most systems and necessary service/reset functions. They are ideal for specialized workshops, dealerships, or individuals who require multi-system diagnostics without the investment of a universal, all-cars scan tool. For example, a mechanic specializing in BMW and Mercedes-Benz could opt for a single-make scanner covering these two brands, achieving in-depth diagnostics without paying for coverage they won’t use.

6. Professional OBD Scan Tools
Professional OBD scan tools represent the pinnacle of diagnostic capability. These are the best OBD II scanner types for workshops and mechanics demanding comprehensive diagnostics, extensive Australian market car coverage, and advanced bi-directional, coding, and programming functions. Professional scanners often incorporate enhanced hardware features to further expand diagnostic potential. These features may include online databases and support, customer management systems, integrated oscilloscopes for advanced signal analysis, faster processing for quicker scan times, and more. Investing in a professional-grade tool equips workshops to handle complex diagnostic challenges and offer a wider range of services.

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 OBD II scanner types execute crucial maintenance tasks, including 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 programming, DPF regeneration, and numerous other maintenance procedures. These tools are essential for workshops aiming to efficiently perform routine maintenance and complex service procedures in-house.
8. OBD1 to OBD2 Cable Adapters
OBD1 to OBD2 cable adapters bridge the gap between older, pre-OBD2 vehicles and modern OBD scanners. These cables and adapters facilitate connection to vehicles utilizing manufacturer-specific OBD ports that predate the standardized OBD2 format. While the adapter ensures physical connectivity, you still require an OBD scanner capable of interpreting the specific diagnostic protocols and parameters used by the older vehicle. These adapters are vital for workshops servicing a mix of classic and modern vehicles, allowing them to leverage their OBD2 scan tools on a wider range of cars.
