OBD2 Scanners – Find the Right Diagnostic Tool for Your Car
OBD2 scanners can help you read fault codes, view live data and diagnose problems across different vehicle systems. The right diagnostic tool depends on the vehicles you work on, the functions you need and whether you prefer a standalone scanner or a smartphone-based solution.
Which OBD2 Scanner Do You Need?
There is no single scanner that is best for every vehicle or user. Start by choosing the type of diagnostic tool that matches how you plan to use it.
Single-Brand Diagnostic Scanners
Single-brand diagnostic scanners are designed for users who mainly work on vehicles from one manufacturer. Compared with basic universal code readers, they can provide broader access to manufacturer-specific systems and service functions on supported vehicles.
- Best suited to one vehicle brand or manufacturer group
- Full-system diagnostics on supported vehicles
- Live data and freeze-frame information
- Service and maintenance functions depending on the scanner
- A good choice when manufacturer-specific coverage matters

Bluetooth and App-Based OBD Scanners
Bluetooth diagnostic tools connect the vehicle to a smartphone or tablet instead of using a dedicated handheld display. They can be a compact and convenient option, but diagnostic capability varies significantly between basic OBD2 adapters and manufacturer-specific platforms.
- Uses a smartphone or tablet as the interface
- Compact and easy to keep in the vehicle
- Can provide live data and fault-code functions
- Some platforms offer manufacturer-specific diagnostics, coding and adaptations
