Product Description


OBDLink Wi-Fi is our latest, most advanced scan tool that supports all OBD-2 compliant vehicles. In addition to operating wirelessly via WiFi, it includes a built-in USB interface.

The package includes everything you need to diagnose your vehicle's problems and access performance parameters. OBDLink features the industry-leading data throughput to capture more graph points and faster screen updates.

The free feature-packed OBDwiz diagnostic software (for Windows) included with the scan tool allows you to:

  • Turn off check engine light, and erase stored diagnostic information
  • Read and erase stored, pending, and permanent trouble codes (both generic and manufacturer-specific)
  • Access freeze frame information
  • Display, graph, and log 90+ real-time parameters
  • Create custom digital dashboards
  • Measure and display fuel economy
  • And much more!

Premium diagnostic software, such as ScanXL and ScanMaster, offers a myriad of additional features including Dynometer, multi-language support, and data manipulation tools . ScanXL’s Enhanced Diagnostics Add-ons offer support for thousands of enhanced manufacturer-specific parameters, as well as ABS and other proprietary systems.
